4 - TROUBLESHOOTING
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.

Checks to make, possible causes
0
NO FAULT
1
MOTOR
OVERHEATING
Red LED illuminated
overheating fault I
2
t
- 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
2
OVERVOLTAGE
Red LED flashing
- check the mains supply voltage
- check that the deceleration ramp is long enough for applications with high inertia
3
OVERCURRENT
Red LED illuminated
- 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
4
LOCKED ROTOR
Red LED illuminated
- check if the motor is overloaded or has stalled (green LED flashing)
5
BUS UNDERVOLTAGE
Red LED flashing
- check the mains supply voltage
6
EEPROM
Red LED illuminated
- make sure that the VARMECA 10 is not affected by interference
- internal product fault
7
SERIAL LINK
Red LED illuminated
- communication fault between the EEPROM and the controller - product fault
8
MODULE FAULT
Red LED illuminated
- 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
FAULTS CAN ONLY BE CLEARED BY SWITCHING OFF THE VARMECA 10.
Fault specific to the use of the CDC-VMA
console
