POSSIBLE CAUSE
1. Motor characterization failed during
characterization process. See
Monitor menu » Controller: Motor
Characterization Error for cause:
0 = sequencing error. Normally caused
by turning off Motor Characterization
Test Enable before running the test.
1 = encoder signal seen but step size not
auto-detected; set up Encoder Steps
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 or
both channels missing
9 = motor parameters out of
characterization range
20 = Sin/Cos sensor not found
21 = phasing not detected
22 = Sin/Cos sensor characterization
failure
23 = started characterization procedure
while motor rotating.
1. Encoder Steps parameter does not
match the actual motor encoder.
2. The Motor_Type parameter value is out
of range.
SET / CLEAR CONDITIONS
Set: Motor characterization failed during the motor
characterization process.
Normally caused by turning off
Motor_Characterization_Test_Enable before
running test. Needs controller reset.
Clear: Correct fault; cycle KSI, or VCL reset.
Set: Detected wrong setting of the Encoder Steps
parameter.
Clear: Ensure the Encoder Steps parameter
matches the actual encoder; cycle KSI.
Set: Motor_Type parameter is set to an illegal
value.
Clear: Set Motor_Type to correct value and cycle
KSI.
