Chapter 10 Troubleshooting the Drive
SW OverCurrent 36 The drive output current has exceeded the software current
limit.
Check for excess load, improper DC boost setting. DC brake volts set too
high.
UnderVoltage 4
DC bus voltage fell below the minimum value of: 305V DC
input.
Enable/disable with inverter Fault Config 1(238).
Monitor the incoming AC line for low voltage or power interruption.
UserSet1 Chksum 101 The checksum read from the user set does not match the
checksum calculated.
These faults can be cleared by writing a nonzero value to
inverter Save To User Set (199).
Re-save user set using inverter Save To User Set (199).
UserSet2 Chksum 102
UserSet3 Chksum 103
