Faults are indicated on the CDC-VMA console by a code from
0 to 8.
With the PEGASE VMA 10 software the faults are indicated
clearly in the fault window.
The table below can be used to analyse faults and specifies
any checks which should be performed.

TROUBLESHOOTING
- check if the motor is overloaded
(orange LED illuminated)
- check the set rating and the motor power
- make sure that the boost adjustment (P11) has not been modified
- check the mains supply voltage
- check that the deceleration ramp is long enough for applications with high inertia
- check that there is no short circuit occurring from a motor winding or on the
connections
- check the motor insulation
- check that the deceleration ramp is long enough for applications with high inertia
- check the set rating and the motor power
- internal product fault
- check if the motor is overloaded or has stalled (green LED flashing)
- check the mains supply voltage
- make sure that the VARMECA 10 is not affected by interference
- internal product fault
- communication fault between the EEPROM and the controller - product fault
- very sudden overcurrent (possible causes: see OVERCURRENT fault)
- IGBT power module overheating. Check that the unit is not operating at an
ambient temperature which is too high
- IGBT power module fault. Internal product fault
- Check the connection cable.
- Check that the VARMECA 10 is correctly supplied.
- Check the connection cable.
- Check that the VARMECA 10 is correctly supplied.
- Check that the serial port is correctly configured.
