4.8.3 Enabling Motor Operation (Terminal 27)
A jumper wire may be required between terminal 12 (or 13) and terminal 27 for the adjustable frequency drive to operate when using factory default programming values.
· Digital input terminal 27 is designed to receive an
24 V DC external interlock command. In many applications, the user wires an external interlock device to terminal 27
· When no interlock device is used, wire a jumper
between control terminal 12 (recommended) or 13 to terminal 27. This provides an internal 24 V signal on terminal 27.
· No signal present prevents the unit from operating. · When the status line at the bottom of the LCP
reads AUTO REMOTE COAST, this indicates that the unit is ready to operate but is missing an input signal on terminal 27.
· When factory installed optional equipment is wired
to terminal 27, do not remove that wiring
NOTICE!
The adjustable frequency drive cannot operate without a signal on terminal 27 unless terminal 27 is re-programmed.
4.8.4 Voltage/Current Input Selection (Switches)

NOTICE!
Remove power to the adjustable frequency drive before changing switch positions.
1. Remove the local control panel (see Figure 4.14). 2. Remove any optional equipment covering the
switches. 3. Set switches A53 and A54 to select the signal type.
U selects voltage, I selects current.

4.8.6 RS-485 Serial Communication
Up to 32 nodes can be connected as a bus, or via drop cables from a common trunk line to one network segment. Repeaters can divide network segments. Each repeater functions as a node within the segment in which it is installed. Each node connected within a given network must have a unique node address across all segments.
· Connect RS-485 serial communication wiring to
terminals (+)68 and (-)69.
· Terminate each segment at both ends, using either
the termination switch (bus term on/off, see Figure 4.14) on the adjustable frequency drives, or a biased termination resistor network.
· Connect a large surface of the shield to ground, for
example with a cable clamp or a conductive cable connector.
· Apply potential-equalizing cables to maintain the
same ground potential throughout the network.
· Use the same type of cable throughout the entire
network to prevent impedance mismatch.

Programming motor data After selecting PM motor in 1-10 Motor Construction, the PM motor-related parameters in parameter groups 1-2 Motor Data, 1-3 Addl. Motor Data and 1-4* are active. The necessary data can be found on the motor nameplate and in the motor data sheet. Program the following parameters in the listed order
1. 1-24 Motor Current 2. 1-26 Motor Cont. Rated Torque 3. 1-25 Motor Nominal Speed 4. 1-39 Motor Poles

5. 1-30 Stator Resistance (Rs) Enter line to common stator winding resistance (Rs). If only line-line data are available, divide the lineline value by 2 to achieve the line to common (starpoint) value. It is also possible to measure the value with an ohmmeter, which will also take the resistance of the cable into account. Divide the measured value by 2 and enter the result.
6. 1-37 d-axis Inductance (Ld) Enter line to common direct axis inductance of the PM motor. If only line-line data are available, divide the lineline value by 2 to achieve the line-common (starpoint) value. It is also possible to measure the value with an inductance meter, which will also take the inductance of the cable into account. Divide the measured value by 2 and enter the result.
7. 1-40 Back EMF at 1000 RPM Enter line-to-line back EMF of PM Motor at 1000 RPM mechanical speed (RMS value). Back EMF is the voltage generated by a PM motor when no drive is connected and the shaft is turned externally. Back EMF is normally specified for nominal motor speed or for 1000 RPM measured between two lines. If the value is not available for a motor speed of 1000 RPM, calculate the correct value as follows: If back EMF is, e.g., 320 V at 1800 RPM, it can be calculated at 1000 RPM as follows: Back EMF = (Voltage / RPM)1000 = (320/1800)1000 = 178. This is the value that must be programmed for 1-40 Back EMF at 1000 RPM.
Test Motor Operation
1. Start the motor at low speed (100 to 200 RPM). If the motor does not turn, check installation, general programming and motor data.
2. Check if start function in 1-70 PM Start Mode fits the application requirements.
Rotor detection This function is the recommended choice for applications where the motor starts from standstill, e.g., pumps or conveyors. On some motors, an acoustic sound is heard when the impulse is sent out. This does not harm the motor.

Motor speed is below the value set in 4-52 Warning Speed Low. In Auto On mode, the adjustable frequency drive will start the motor with a start signal from a digital input or serial communication. In 1-71 Start Delay, a delay starting time was set. A start command is activated and the motor will start after the start delay time expires. Start forward and start reverse were selected as functions for two different digital inputs (parameter group 5-1* Digital Inputs). The motor will start in forward or reverse depending on which corresponding terminal is activated. The adjustable frequency drive has received a stop command from the LCP, digital input or serial communication. An alarm occurred and the motor is stopped. Once the cause of the alarm is cleared, the adjustable frequency drive can be reset manually by pressing [Reset] or remotely by control terminals or serial communication.

Trip lock

An alarm occurred and the motor is stopped. Once the cause of the alarm is cleared, power must be cycled to the adjustable frequency drive. The adjustable frequency drive can then be reset manually by pressing [Reset] or remotely by control terminals or serial communication.

Table 7.4 Operation Status

NOTICE!
In auto/remote mode, the adjustable frequency drive requires external commands to execute functions.

7.2 Warning and Alarm Types
Warnings A warning is issued when an alarm condition is impending or when an abnormal operating condition is present and may result in the adjustable frequency drive issuing an alarm. A warning clears by itself when the abnormal condition is removed.
Alarms Trip An alarm is issued when the adjustable frequency drive is tripped, which means that the adjustable frequency drive suspends operation to prevent adjustable frequency drive or system damage. The motor will coast to a stop. The adjustable frequency drive logic will continue to operate and monitor the adjustable frequency drive status. After the fault condition is remedied, the adjustable frequency drive can be reset. It will then be ready to start operation again.
Resetting the adjustable frequency drive after trip/trip lock A trip can be reset in any of four ways:
· Press [Reset] on the LCP · Digital reset input command · Serial communication reset input command · Auto reset
Trip lock Input power is cycled. The motor coasts to a stop. The adjustable frequency drive continues to monitor the adjustable frequency drive status. Remove input power to the adjustable frequency drive, correct the cause of the fault, and reset the adjustable frequency drive.

7.3 List of Warnings and Alarms
The warning/alarm information below defines each warning/ alarm condition, provides the probable cause for the condition, and details a remedy or troubleshooting procedure.
WARNING 1, 10 Volts low The control card voltage is below 10 V from terminal 50. Remove some of the load from terminal 50, as the 10 V supply is overloaded. Max. 15 mA or minimum 590 .
A short circuit in a connected potentiometer or improper wiring of the potentiometer can cause this condition.
Troubleshooting Remove the wiring from terminal 50. If the warning clears, the problem is with the wiring. If the warning does not clear, replace the control card.
WARNING/ALARM 2, Live zero error This warning or alarm only appears if programmed in 6-01 Live Zero Timeout Function. The signal on one of the analog inputs is less than 50% of the minimum value programmed for that input. Broken wiring or faulty device sending the signal can cause this condition.
Troubleshooting Check connections on all the analog input terminals. Control card terminals 53 and 54 for signals, terminal 55 common. MCB 101 terminals 11 and 12 for signals, terminal 10 common. MCB 109 terminals 1, 3, 5 for signals, terminals 2, 4, 6 common).
Check that the frequency converter programming and switch settings match the analog signal type.
Perform Input Terminal Signal Test.
WARNING/ALARM 4, Mains phase loss A phase is missing on the supply side, or the line voltage imbalance is too high. This message also appears for a fault in the input rectifier on the adjustable frequency drive. Options are programmed at 14-12 Function at Mains Imbalance.
Troubleshooting Check the supply voltage and supply currents to the adjustable frequency drive.

WARNING 5, DC link voltage high The intermediate circuit voltage (DC) is higher than the highvoltage warning limit. The limit is dependent on the frequency converter voltage rating. The unit is still active.
WARNING 6, DC link voltage low The intermediate circuit voltage (DC) is lower than the lowvoltage warning limit. The limit is dependent on the frequency converter voltage rating. The unit is still active.
WARNING/ALARM 7, DC overvoltage If the intermediate circuit voltage exceeds the limit, the adjustable frequency drive trips after a time.
Troubleshooting Connect a brake resistor
Extend the ramp time
Change the ramp type
Activate the functions in 2-10 Brake Function
Increase 14-26 Trip Delay at Inverter Fault
If the alarm/warning occurs during a power sag, use kinetic backup (14-10 Line Failure)
WARNING/ALARM 8, DC under voltage If the intermediate circuit voltage (DC link) drops below the under voltage limit, the frequency converter checks if a 24 V DC back-up supply is connected. If no 24 V DC back-up supply is connected, the frequency converter trips after a fixed time delay. The time delay varies with unit size.
Troubleshooting Check that the supply voltage matches the frequency converter voltage.
Perform input voltage test.
Perform soft charge circuit test.
WARNING/ALARM 9, Inverter overload The frequency converter is about to cut out because of an overload (too high current for too long). The counter for electronic, thermal inverter protection issues a warning at 98% and trips at 100%, while giving an alarm. The frequency converter cannot be reset until the counter is below 90%. The fault is that the frequency converter has run with more than 100% overload for too long.
Troubleshooting Compare the output current shown on the LCP with the frequency converter rated current.
Compare the output current shown on the LCP with measured motor current.

Display the Thermal Drive Load on the LCP and monitor the value. When running above the frequency converter continuous current rating, the counter increases. When running below the frequency converter continuous current rating, the counter decreases.

Table 8.10 Line Power Supply 3 x 525­690 V – Normal overload 110% for 1 minute, P37K-P90K

1. For type of fuse, see 8.8 Fuse Specifications. 2) American Wire Gauge. 3) Measured using 5 m shielded motor cables at rated load and rated frequency. 4) The typical power loss is at normal load conditions and expected to be within ±15% (tolerance relates to variety in voltage and cable conditions). Values are based on a typical motor efficiency. Lower efficiency motors will also add to the power loss in the adjustable frequency drive and vice versa. If the switching frequency is raised from nominal, the power losses may rise significantly. LCP and typical control card power consumption values are included. Further options and customer load may add up to 30 W to the losses. (Though typically only 4 W extra for a fully loaded control card or options for slot A or slot B, each). Although measurements are made with state-of-the- art equipment, some measurement inaccuracy must be allowed for (±5%). 5) The three values for the max. cable cross-section are for single core, flexible wire and flexible wire with sleeve, respectively. Motor and line cable: 300 MCM/150 mm2. 6) A2+A3 may be converted to IP21 using a conversion kit. See also Mechanical mounting and IP21/Type 1 Enclosure kit in the Design Guide. 7) B3+4 and C3+4 may be converted to IP21 using a conversion kit. See also Mechanical mounting and IP21/Type 1 Enclosure kit in the Design Guide.

AC line voltage low/line drop-out: During low AC line voltage or a line drop- out, the adjustable frequency drive continues until the intermediate circuit voltage drops below the minimum stop level, which typically corresponds to 15% below the adjustable frequency drive’s lowest rated supply voltage. Power-up and full torque cannot be expected at AC line voltage lower than 10% below the adjustable frequency drive’s lowest rated supply voltage.

All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals. 1) Terminals 27 and 29 can also be programmed as output. 2) Except Safe Torque Off input Terminal 37. 3) See for further information about terminal 37 and Safe Torque Off. 4) When using a contactor with a DC coil inside in combination with Safe Torque Off, it is important to make a return way for the current from the coil when turning it off. This can be done by using a freewheel diode (or, alternatively, a 30 or 50 V MOV for quicker response time) across the coil. Typical contactors can be bought with this diode.
