Table 7-1: Troubleshooting Guide
PROBLEM: Voltage is not present at the filter input terminals.
Possible cause: Power to the filter is turned off or shut down.
Solution:
Turn power on; check drive errors.
Possible cause: One or more external line fuses are blown.
Solution: Verify the continuity of line fuses in all phases. Replace as necessary.
Possible cause: Damage to drive – dV E-Series interconnect cables.
Solution: Replace damaged cables.
Possible cause: Drive setup parameters are incorrect.
Solution: Verify motor current, voltage, and shutdown parameters are valid.
PROBLEM: dV E-Series filter runs Hot
Possible cause:
Normal operation, reactor > 150° C and resistors > 300° C.
Solution:
Caution: Parts are very hot and may cause burns. Follow installation
guidelines for clearance and check for adequate air flow.
Possible cause: Motor coil damage: windings shorted.
Solution: Replace motor; inspect wiring.
Possible cause:
Heat buildup within enclosure.
Solution Provide clearance and venting for filter components.
Possible cause: Heat buildup within enclosure.
Solution Check carrier frequency and overload settings.
Possible cause:
Multiple motor applications create complex loading and resonances with
dV E-Series filter.
Solution:
dV E-Series filters can be paralleled for higher current ratings. Contact
