Fault Name Causes & Countermeasures
1. The fault may be from Driver Board side.
Switch off the power supply and remove the FRC in case of wire
interface. Check the cable on both the sides for proper crimping.
Insert the cable properly and check again. If the fault persists,
proceed for the next step.
In case of fiber optic interface, remove all the fiber optic cables,
check them and insert them again properly. Check again. If the
fault persists, proceed for the next test.
2. IGBT Gate Driver board may have problem.
Replace the IGBT Gate Driver board and check again. Take anti-
static precautions while changing the board.
3. Check the SMPS supply voltage.
1. Check the encoder wiring.
2. Check the proper earthing of encoder.
3. Problem in auto tuning parameter. Enter the correct motor
parameter and repeat the procedure for auto tuning.
1. Check the encoder wiring.
2. Check the proper earthing of encoder.
3. Problem in auto tuning parameter. Enter the correct motor
parameter and repeat the procedure for auto tuning.
Inverter or diode unit in case of parallel inverter.
Replace it if necessary.
2. The ambient temperature may have risen.
Lower the ambient temperature (less than 50 °C for 400 V series or
less than 40 ° C for 500 V / 600 V series).
3. The carrier frequency may be set too high.
4. The thermistor is not connected or loosely connected at J16 of
PCA-2014A and TB1 of PCA-2013A / TB-1 to TB7 of PCA-2049A
respectively. Disconnect the thermistor and ensure that the
thermistor shows resistance greater than 2.2 k , but less than 60
k . Reconnect thermistor properly.
J15 of PCA-2013A.
Switch off the unit and remove the cable. Check for proper crimping
of cable on both sides. If found abnormal, replace the cable and
check again.
2. One or more current sensor has failed.
Remove connector J11 to J15 and reset the fault. If the fault can be
reset, find out which current sensor has failed.
3. If after removing connector J11 to J15, the problem persists,
replace PCA- 2013A.
1. Check whether the sensors are connected properly or not. If the
sensor of one or more Inverter Unit is not connected, this fault may
come.
2. There may be problem with the driver board or fiber optic cable.
Check the driver board and fiber optic connections. If required
replace it.
3. There may be loose connection of the fiber optic cable or problem
with the Fiber Optic Interface Board PCA-96A. Checks the
connection with of the fiber optic cables are if required change the
PCA-96A.
4. Check the current sensor connections at Driver Interface Board
PCA-2013A/ PCA-2049A or at adapter board PCA-185. If required,
change the board.
