Cause / Remedy
•
Check and correct duty cycle
•
Check if motor name plate information has been entered correctly –
if not, then re-perform quick commissioning using correct data. Most
common incorrect parameter is P0309 (motor efficiency). If this
value is too low, the calculated temperature will be incorrect.
•
Perform Motor ID P1910=1 on a cold motor
•
Check that motor weight is correct (P0344 – correct if necessary)
•
If temperature sensors are fitted, check r0035 to see if they are
realistic, if not check that you have the correct type of sensor.
•
DC Link over current – check the following; Chopper short circuit,
braking resistor resistance too low, ground fault on output, IGBT
failure (disconnect motor leads and try to run – if fault still occurs
then IGBT failure has occurred)
•
I/O board not properly seated – remove and re-clip into position.
•
Poor Grounding on motor leads – check and improve if necessary.
•
Check that motor is connected.
•
Check that ALL motor data is correct for wiring designation
(Wye/Delta) – Re-perform quick commissioning to correct this if
necessary.
•
Signal wire broken – check and correct
•
Signal out of range – check and correct
•
External fault signal activated – reset active external fault
•
Cable length limits must not be exceeded
•
Motor cable and motor must have no short-circuits or earth faults
•
Motor parameters must match the motor in use
•
Value of stator resistance (P0350) must be correct
•
Motor must not be obstructed or overloaded
•
Increase the ramp-up-time.
•
Reduce the boost level (V/f control: P1311 & P1312, Vector control:
P1610 & P1611)
•
Motor power (P0307) must correspond to inverter power (r0206)
•
Supply voltage (P0210) must lie within limits indicated on drive
name plate
•
DC-link voltage controller must be enabled (P1240) and
parameterized properly
•
Ramp-down time (P1121) must match inertia of load
•
Required braking power must lie within specified limits
•
Supply voltage (P0210) must lie within limits indicated on rating
plate
•
Supply must not be susceptible to temporary failures or voltage
reductions
•
Enable kinetic buffering (P1240 = 2)
•
Load conditions and duty cycle must be appropriate
•
Fan must turn when inverter is running
•
Pulse frequency (P1800) must be set to default value
•
Ambient temperature could be higher than specified for the inverter
•
Load duty cycle must lie within specified limits
