1. Motor characterization failed
during characterization
process. See Monitor
menu » Controller: Motor
Characterization Error for
cause:
0=none
1=encoder signal seen, but
step size not determined; set
Encoder Step Size manually
2=motor temp sensor fault
3=motor temp hot cutback
fault
4= controller overtemp cutback
fault
5=controller undertemp
cutback fault
6=undervoltage cutback fault
7=severe overvoltage fault
8=encoder signal not seen, or
one both channels missing
9=motor parameters out of
characterization range.
Set: Motor characterization
failed during the motor
characterization process.
Clear: Correct fault; cycle KSI.
