2. Grounding capacitor disconnecting switch and taps

E6581158

Warning

The grounding capacitor disconnecting tap is provided with a protection cover. To avoid shock hazards,

always attach the cover after connecting or disconnecting the capacitor to or from the tap.

Mandatory

1
Every single-phase 240V/three-phase 500V model has a built-in high-attenuation noise filter, which is

grounded through a capacitor.

If you want to disconnect the capacitor from the grounding line to reduce the amount of leakage current,

you can do so easily using the switch or tap. Keep in mind, however, that disconnecting the capacitor

from the grounding line causes the inverter to become non-compliant with the EMC directive. Also note

that the inverter must always be turned off before the capacitor is disconnected or reconnected.

Note) In case of three phase 500V-4.0kW model, if you disconnect the capacitor from ground, set the parameter of carrier frequency f300 to 4kHz or less with motor cable length 30m or less.

1.4 Notes on the application

E6581158

1.4.1 Motors

When the VF-S11 and the motor are used in conjunction, pay attention to the following items.

1

Warning

Use an inverter that conforms to the specifications of power supply and three- phase induction motor

being used. If the inverter being used does not conform to those specifications, not only will the three-

phase induction motor not rotate correctly, but it may cause serious accidents through overheating and Mandatory
fire.

Comparisons with commercial power operation.
The VF-S11 Inverter employs the sinusoidal PWM system. However, the output voltage and output current are not perfect sine waves, they have a distorted wave that is close to sinusoidal waveform. This is why compared to operation with a commercial power there will be a slight increase in motor temperature, noise and vibration.

Operation in the low-speed area
When running continuously at low speed in conjunction with a general purpose motor, there may be a decline in that motor’s cooling effect. If this happens, operate with the output decreased from rated load. To carry out low-speed operation continuously at the rated torque, we recommend to use a inverter rated motor or a forced cooled motor designed for use with an inverter. When operating in conjunction with a inverter rated motor, you must change the inverter’s motor overload protection level to VF motor use (QNO).

Adjusting the overload protection level
The VF-S11 Inverter protects against overloads with its overload detection circuits (electronic thermal). The electronic thermal’s reference current is set to the inverter’s rated current, so it must be adjusted in line with the rated current of the general purpose motor being used in combination.

High speed operation at and above 60Hz
Operating at frequencies greater than 60Hz will increase noise and vibration. There is also a possibility this will exceed the motor’s mechanical strength limits and the bearing limits so you should inquire to the motor’s manufacturer about such operation.

Method of lubricating load mechanisms
Operating an oil-lubricated reduction gear and gear motor in the low-speed areas will worsen the lubricating effect. Check with the manufacturer of the reduction gear to find out about operable gearing area.

A-12

E6581158

Low loads and low inertia loads
The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of 50 % or under of the load percentage, or when the load’s inertia moment is extremely small. If that happens reduce the carrier frequency.

Occurrence of instability

Unstable phenomena may occur with the load and motor combinations shown below.

Combined with a motor that exceeds applicable motor ratings recommended for the inverter

1

Combined with special motors

For 600V class or 500V class with long cable

To deal with the above lower the settings of inverter carrier frequency.

Combined with couplings between load devices and motors with high backlash

When using the inverter in the above combination, use the S-pattern acceleration/deceleration function,

or when vector control is selected, adjust the speed control response/stability factor or switch to V/f

control mode.

Combined with loads that have sharp fluctuations in rotation such as piston movements

In this case, adjust the response time (inertial moment setting) during vector control or switch to V/f

control.

Braking a motor when cutting off power supply
A motor with its power cut off goes into free-run, and does not stop immediately. To stop the motor quickly as soon as the power is cut off install an auxiliary brake. There are different kinds of brake devices, both electrical and mechanical. Select the brake that is best for the system.

Load that produces regenerative torque
When combined with a load that produces regenerative torque, the overvoltage or overcurrent protection function may be activated to trip the inverter. For this kind of situation, you must install a dynamic braking resistor that complies with the load conditions, or increase deceleration time.

A-13

E6581158

Braking motor
When using a braking motor, if the braking circuit is directly connected to the inverters’s output terminals, the brake cannot be released because of the lowered starting voltage. Therefore, when using a braking motor, connect the braking circuit to the inverter’s power supply side, as shown in the figure below. Usually, braking motors produce larger noise in low speed ranges.

Note: In the case of the circuit shown on the below, assign the function of detecting low-speed signals

to the RY and RC terminals. Make sure the parameter f130 is set to 4 (factory default setting).

Measures to protect motors against surge voltages
In a system in which a 500V-class inverter is used to control the operation of a motor, very high surge voltages may be produced. When applied to the motor coils repeatedly for a long time, may cause deterioration of their insulation, depending on the cable length, cable routing and types of cables used. Here are some examples of measures against surge voltages. (1) Lower the inverter’s carrier frequency. (2) Set the parameter f316 (Carrier frequency control mode selection) to 2 or 3. (3) Use a motor with high insulation strength. (4) Insert an AC reactor or a surge voltage suppression filter between the inverter and the motor.

1.4.2 Inverters

Protecting inverters from overcurrent
The inverter has an overcurrent protection function. The programmed current level is set to the inverter’s maximum applicable motor. If the motor used has a small capacity, the overcurrent level and the electronic thermal protection must be readjusted. If adjustment is necessary, see 5-13, and make adjustments as directed.
Inverter capacity
Do not use a small-capacity (kVA) inverter to control the operation of a large-capacity motor (two-class or more larger motor), no matter how light the load is. Current ripple will raise the output peak current making it easier to set off the overcurrent trip.

A-14

E6581158
Power factor correction capacitor
Power factor correction capacitors cannot be installed on the output side of the inverter. When a motor is run that has a power factor correction capacitor attached to it, remove the capacitors. This can cause inverter malfunction trips and capacitor destruction.

Operating at other than rated voltage
Connections to voltages other than the rated voltage described in the rating label cannot be made. If a connection must be made to a power supply other than one with rated voltage, use a transformer to raise or lower the voltage to the rated voltage.

INVn

There is no fuse in the inverter’s main circuit. Thus, as the diagram above shows, when more than one inverter is used on the same power line, you must select interrupting characteristics so that only the MCCB2 will trip and the MCCB1 will not trip when a short occurs in the inverter (INV1). When you cannot select the proper characteristics install a circuit interrupting fuse between the MCCB2 and the INV1.

If power supply distortion is not negligible
If the power supply distortion is not negligible because the inverter shares a power distribution line with other systems causing distorted waves, such as systems with thyristors or large-capacity inverters, install an input reactor to improve the input power factor, to reduce higher harmonics, or to suppress external surges.

A-15

Disposal
If an inverter is no longer usable, dispose of it as industrial waste.
1.4.3 What to do about the leak current

E6581158

Warning

1

Current may leak through the inverter’s input/output wires because of insufficient electrostatic capacity on the motor with

bad effects on peripheral equipment.

The leakage current’s value is affected by the carrier frequency and the length of the input/output wires. Test and adopt

the following remedies against leak current.

(1) Effects of leak current across ground
Leakage current may flow not just through the inverter system but also through ground wires to other systems. Leakage current will cause earth leakage breakers, leakage current relays, ground relays, fire alarms and sensors to operate improperly, and it will cause superimposed noise on the CRT screen or display of incorrect current detection with the CT.

Remedies:
1.If there is no radio-frequency interference or similar problem, detach the built-in noise filter capacitor, using the grounding capacitor disconnecting switch or tap. (See 1.3.2-2)
2.Reduce PWM carrier frequency. The setting of PWM carrier frequency is done with the parameter H. Although the electromagnetic noise level is reduced, the motor acoustic noise is increased.
3. Use high frequency remedial products for earth leakage breakers.

(1) Thermal relays The high frequency component of current leaking into electrostatic capacity between inverter output wires will increase the effective current values and make externally connected thermal relays operate improperly. If the wires are more than 50 meters long, it will be easy for the external thermal relay to operate improperly with models having motors of low rated current (several A(ampere) or less), especially the 500V and 600V class low capacity (3.7kW or less) models, because the leak current will increase in proportion to the motor rating.
Remedies:
1.Use the electronic thermal built into the inverter. (See 5.13) The setting of the electronic thermal is done using parameter QNO, VJT.
2.Reduce the inverter’s PWM carrier frequency. However, that will increase the motor’s magnetic noise. The setting of PWM carrier frequency is done with the parameter H. (See 6.12)
3.This can be improved by installing 0.1µ~0.5µF – 1000V film capacitor to the input/output terminals of each phase in the thermal relay.

E6581158

(2) CT and ammeter

If a CT and ammeter are connected externally to detect inverter output current, the leak current’s high

frequency component may destroy the ammeter. If the wires are more than 50 meters long, it will be

easy for the high frequency component to pass through the externally connected CT and be

superimposed on and burn the ammeter with models having motors of low rated current (several

A(ampere) or less), especially the 500V and 600V class low capacity (3.7kW or less) models, because

the leak current will increase in proportion to the motor’s rated current.

1

Remedies:

1.Use a meter output terminal in the inverter control circuit. The load current can be output on the meter output terminal (FM). If the meter is connected, use an ammeter of 1mAdc full scale or a voltmeter of 7.5V-1mA full scale. 0-20mAdc (4-20mAdc) can be also output. (See 5.5)
2.Use the monitor functions built into the inverter. Use the monitor functions on the panel built into the inverter to check current values. (See 8.1.1)

The space shown in the diagram is the minimum allowable space. Because air cooled equipment has cooling fans built in on the top or bottom surfaces, make the space on top and bottom as large as possible to allow for air passage. Note: Do not install in any location where there is high humidity or high temperatures and where there are
large amounts of dust, metallic fragments and oil mist.
Calorific values of the inverter and the required ventilation
About 5% of the rated power of the inverter will be lost as a result of conversion from AC to DC or from DC to AC. In order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the interior of the cabinet must be ventilated and cooled.
The amount of forcible air-cooling ventilation required and the necessary heat discharge surface quantity when operating in a sealed cabinet according to motor capacity are as follows.
Notes 1) The heat loss for the optional external devices (input reactor, DC reactor, radio noise reduction filters,
etc.) is not included in the calorific values in the table 2) Case of 100% Load Continuation operation.

Panel designing taking into consideration the effects of noise
The inverter generates high frequency noise. When designing the control panel setup, consideration must be given to that noise. Examples of measures are given below. · Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the
same conduit, do not run them parallel, and do not bundle them. · Provide shielding and twisted wire for control circuit wiring. · Separate the input (power) and output (motor) wires of the main circuit. Do not place them in the same
conduit, do not run them parallel, and do not bundle them.
· Ground the inverter ground terminals ( ). · Install surge suppressor on any magnetic contactor and relay coils used around the inverter. · Install noise filters if necessary.

A-22

· Install EMC plate and use shielded wires.

· When transporting or carrying, do not hold by the front panel covers. The covers may come off and the unit will drop out resulting in injury.

2.1 Cautions on wiring

Prohibited Mandatory

Danger
· Never remove the front cover when power is on or open door if enclosed in a cabinet. The unit contains many high voltage parts and contact with them will result in electric shock.
· Turn power on only after attaching the front cover or closing door if enclosed in a cabinet. If power is turned on without the front cover attached or closing door if enclosed in a cabinet. This can result in electric shock or other injury.
· Electrical construction work must be done by a qualified expert. Connection of input power by someone who does not have that expert knowledge may result in fire or electric shock.
· Connect output terminals (motor side) correctly. If the phase sequence is incorrect, the motor will operate in reverse and that may result in injury.
· Wiring must be done after installation. If wiring is done prior to installation that may result in injury or electric shock.
· The following steps must be performed before wiring. (1) Shut off all input power. (2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit. (3) Use a tester that can measure DC voltage (800VDC or more), and check to make sure that the voltage to the DC main circuits (across PA-PC) is 45V or less. If these steps are not properly performed, the wiring will cause electric shock.
· Tighten the screws on the terminal board to specified torque. If the screws are not tightened to the specified torque, it may lead to fire.

(motor side) terminal.

2

Prohibited

This could cause a fire.

Preventing radio noise
To prevent electrical interference such as radio noise, separately bundle wires to the main circuit’s power terminals (R/L1, S/L2, T/L3) and wires to the motor terminals (U/T1, V/T2, W/T3).

Control and main power supply
The control power supply and the main circuit power supply for the VFS11 are the same. (See 6.19.3) If a malfunction or trip causes the main circuit to be shut off, control power will also be shut off. When checking the cause of the malfunction or the trip, use the trip holding retention selection parameter.

Wiring
· Because the space between the main circuit terminals is small use sleeved pressure terminals for the connections. Connect the terminals so that adjacent terminals do not touch each other.
· For ground terminal use wires of the size that is equivalent to or larger than those given in table 10.1 and always ground the inverter (240V voltage class: D type ground, 500V class: C type ground). Use as large and short a ground wire as possible and wire it as close as possible to the inverter.
· For the sizes of electric wires used in the main circuit, see the table in 10.1. · The length of the main circuit wire in 10-1 should be no longer than 30 meters. If the wire is longer than
30 meters, the wire size (diameter) must be increased.

2.2 Standard connections

Prohibited

Danger
· Do not connect input power to the output (motor side) terminals (U/T1, V/T2, W/T3). Connecting input power to the output could destroy the inverter or cause a fire.
· Do not insert a resistor between DC terminals (between PA/+ and PC/-, or between PO and PC/-). It could cause a fire. See 6.13.4 for the connection of a resistor.
· First shut off input power and wait at least 10 minutes before touching wires on equipment (MCCB) that is connected to inverter power side. Touching the wires before that time could result in electric shock.

SINK (Negative) logic/SOURCE (Positive) logic (When the inverter’s internal power supply is used)
Current flowing out turns control input terminals on. These are called sink logic terminals. (Type: -AN/-WN). The general used method in Europe is source logic in which current flowing into the input terminal turns it on (Typ: -WP). Sink logic is sometimes referred to as negative logic, and source logic is referred to as positive logic. Each logic is supplied with electricity from either the inverter’s internal power supply or an external power supply, and its connections vary depending on the power supply used.
