Over the years, RepairZone technicians have seen many different reasons for Indramat Power Supply failures, especially TVD Series, but some Failure codes are seen far more often. Some of these issues can be a simple quick fix, and some may need a technician to conduct serious inquiries:
Digital Power Supply Display:
-Equipment temperature is too high, if the drive load is not reduced the system will shut down.
When our technicians see this code it is usually a simple fix, it is usually because the unit is not plugged in correctly. So check your plugs first.
LED Diagnostic Displays:
Please Note: Diagnostic displays are only valid if lamp,,24V, plus/minus 15V” is completely lit up.
2. AUX. VOLT (Green fault light off)
-Surcan doesn’t have Auxiliary mains power to run interface card.
-Supply Module fuses defective
Drives will continue only as long as there is sufficient power in the link circuit. Check fuses, the connection and the controller. Do not run drives for longer periods of time at full load because the fan switched off.
3. EARTH CON. (Red fault light on)
-Ground leak in supply module, power wiring, motor, motor cable or drive module.
First you will want to isolate it to be sure the fault is in the drive, not the motor or cable. If it happens to be a ground leak that item will need to be replaced.
4. Tacho (Green fault light off)
-Faulty connection or break in the motor feedback cable
-Excessive motor speed
-Motor feedback defective
-Servo drive module defective
-Fault in BLC signals
Check the connections and replace.
5. BS (Red fault light on)
-Drawing excessive current and the unit will shut down
-Short-circuit or ground leak in cable or connection
-short circuit or ground fault in motor
Hit the reset key once, if the fault does not occur again immediately DO NOT repeatedly hit the reset key as it may cause further damage to motor and drive modules. If reset does not work you may need to replace the cable, drive module, or the servo motor.
