35 OUTPUT WIRING Possible power wiring error detected. When the drive is not running it
monitors for an improper connection between the drive input power and the
drive output. Check for and correct:
• Proper input wiring – line voltageis NOT connected to drive output.
• The fault can be erroneously declared if the input power is a delta
grounded system and motor cable capacitance is large. This fault can be
disabled using parameter 3023
WIRING FAULT.
