Bardac drives K340 Single Phase DC Systems Drives

Product Information: Model K340 / K680 / K1220 DC Drive

The Model K340 / K680 / K1220 DC Drive is a speed controller designed for shunt wound or permanent magnet motors. It utilizes speed feedback from the armature voltage or a shaft mounted tach generator. The drive incorporates an accurate current control loop to protect both the drive and the motor. It is a non-isolated component and should only be installed by qualified personnel. Safety precautions should be taken as this component is hazardous. All specifications mentioned in this document are nominal.

Power Rating

K340: 0.55KW (0.5 HP) at 180 Volts DC
K680 : 0.75KW (1.0 HP) at 180 Volts DC
K1220 : 1.8KW (2.0 HP) at 180 Volts DC

Note: The KW/HP ratings are typical motor ratings at or below the available terminal rating of Watts = AV x IA. There are also versions available that work from a 60V/30V AC supply, known as K340/LV60, K680/LV60, and K1220/LV60, suitable for motors rated up to 48V DC.

Maximum Output:

Armature: 200 Volts DC
48V DC for LV60 models
Models K340 / K680 / K1220 : 3.4 / 6.8 / 12.2 Amps
Field: Volts DC = 0.9 x AC supply volts
Field: 1 Amp (0.45 x AC for field connected to F- and N)

Speed Range

40 to 200V (armature volts or tach feedback volts)
LV60 models have an Avf range of 10 – 50V

User Adjustments

Fusing Requirement
Protection must be provided by a correctly rated semi-conductor fuse in the AC supply to the drive. The fuse must have an I2t rating of less than 150 A2s. To satisfy UL requirements for branch circuit short-circuit protection, the specified fuse is a 20A fuse (BUSSMANN FWH020A6F) with a fuseholder 6 X 32mm (CP102071) and a DIN rail clip for the fuseholder (FE101969).

Control Signals

20A fuse (BUSSMANN FWH020A6F)CH00620A
Fuseholder 6 X 32mm CP102071
DIN rail clip for fuseholder FE101969

Suitable for use on a circuit capable of delivering not more than 5000A RMS symmetrical amperes when protected by an aR class fuse.

WARNING
Protection must be provided by a correctly rated semi-conductor fuse, in the AC supply to the drive. The fuse must have an I2t rating of less than 150 A2s.
To satisfy UL requirements for branch circuit short-circuit protection the fuse must be as specified above.

CONTROL SIGNALS
The control signals are NOT isolated from the AC supply. Do not connect them to other instruments.

MECHANICAL
The unit is designed to clip onto a DIN rail. Avoid vibration and ambient temperatures outside –10 and +40C. Protect the unit from pollutants. Ensure there is an adequate supply of clean cool air to ventilate the unit
and the enclosure it is mounted in. (Dissipation in Watts = 5 x Armature Amps).

MOTOR
Foot mounted motors must be level and secure. Protect motors from ingress of foreign matter during installation. Ensure accurate alignmentof motor shaft with couplings. Do not hammer pulleys or couplings onto the motor shaft.

Before running motor, complete the following check list. (Warning isolate the supply first).

Correct insulation between all motor windings and earth. (Disconnect all drive cables prior to testing).
Check inside connection box for foreign objects, damaged terminals etc.
Check that brushes are in good condition, correctly seated and free to move in brush boxes.
Check correct action of brush springs.
Motor vents must be freed of any obstruction or protective covers prior to running.
WARNING for reversing systems. To prevent damage do not transpose the armature connections until the motor has stopped rotating.

Please note this drive does not provide motor over-temperature protection. If required, equip your motor with an external thermal sensor device that can remove the supply when activated by over-temperature.

PRESET POT settings
Set the CURRENT preset to approximately match the motor armaturerating. Fully clockwise is 100% drive rating. (K340
3.4A, K680 6.8A, K1220 12.2A). Fully anticlockwise is 0%. E. g. for a K340unit a midway setting is 50% ie 1.7A. More accurate setting requires a suitable current meter in series with the armature.

Set all the other presets anticlockwise to start off with.
The preferred strategy for initial commissioning is in armature voltage feedback mode described as follows. Set Avf/tach switch ON (left) for armature voltage feedback (AVF) and Spd x 2 switch OFF (right) for 50V max feedback. For systems utilising tach feedback, remove the terminal 6 tach connection.

POWER ON
Check that the Power lamp lights. Increase the external speed pot slowly maximum. The motor should slowly ramp up to around 40V on the motor armature. If the system is to rely on armature voltage feedback you can now set the correct armature voltage and hence speed by using Spd x 2 switch and the Max spd preset (Clockwise to increase speed).

RAMP and MIN SPEED
The up ramp rate can now be set between 20 and 1 seconds. And the Min spd adjusted up to 30%.

IR COMP
Speed droop on heavy loads may occur where armature voltage feedback is used. This is compensated for by clockwise rotation of IR comp. Excessive rotation may lead to instability.
IR Comp is not used with tach feedback, leave preset anticlockwise.

TACH FEEDBACK
With tach feedback it is necessary for the polarity to be negative onterminal 6 with respect to terminal 4, and Avf/tach switch OFF (right). Calculate the maximum feedback voltage from the tach and adjust Spd x 2 switch and Max spd to give the correct speed. ( With Spd x 2 switch OFF (right) Max spd range = 40 to 100V. For Spd x 2 switch ON (left) range = 90 to 200V).

TERMINAL LISTING

WARNING. All terminals are at high potential.
DO NOT TOUCH the terminals or any connected conductor.

+10V output. 2mA max. (Use a 10K Ohm pot for external speed reference).
MIN SPEED. (Connect to minimum end of external speed pot. 5K Ohms preset to common).
SPEED INPUT. 0 to +10V speed input from pot wiper. 39K internal pull down.
COMMON.
RUN. Internal 12K pull up to 12V. Open to stop, close to COMMON to run. WARNING. RUN is anelectronic inhibit function. The field remains energised, and all power terminals ‘live’. RUN mustnot be relied on during hazardous operations.
TACH input. The tach feedback must be negative with respect to COMMON.

A+ Motor armature + Typical form factor 1.5 (load dependant).
A-Motor armature –
F-Motor Field –(No connection required for permanent magnet motors).
F+ Motor Field + (For half wave field volts 0.45 X AC, connect field to F- and N).
N AC supply
L AC supply
Terminal tightening torque 4.4in lb – 0.50Nm

ALARM
Models K680 and K1220 use an internal fan for cooling. The Alarm lamp will come ON and the drive will electronically shut down if the internal fanfails. The field will remain energised, hence if the machine is to be left unattended for long periods it may cause the field to overheat. There is a pair of solder pads adjacent to Terminal 6. If they are linked then the ALARM is inhibited. The unit may be run at currents below 3 Amps without a fan.

JOGGING
For frequent stopping or jogging it is recommended to use T5 RUN input. If you use a mains contactor then connect a spare Normally Open contact on the contactor in series with the RUN input.

AUXILIARY INPUT
In armature voltage feedback the tach input terminal 6 may used a as an auxiliary fast +/- speed trim. (approx 5 -10%)

MECHANICAL DETAILS
The product is enclosed in a stylish DIN rail mounted enclosure with plug in screw terminal connections.

Earthing The terminals are non-isolated hence do not earth. The motor earth should be connected to the system enclosure earth.

WARNING. This product is non-isolated hence all terminals are at dangerous line potential. Ensure connected items (e.g. speed pot, tach etc.) are not earthed and have sufficient dielectric strength to avoid breakdown. Do not touch any part of the unit. Use an insulated tool to adjust the presets. Do not touch when unit is ON.
