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).
