Check the pulse-applied time.
The pulse-applied time can be short.
Set the pulse-applied time longer.
Setting parameter:SP142
1) The pulse-applied time (0 to 350)
2) For low-speed coil:1)+1000
3) The polarity of magnetic pole estimate:
Reverse polarity is "-"
After the adjustment, perform the magnetic
pole detection control again.

The alarm also occurs after the pulse-applied
time is set.
Replace the unit.
Alarm No.

When using dedicated wiring STO function
Is the parameter setting (SV113,SP229/bit8)
correct?
Set SV113,SP229/bit8.
When using dedicated wiring STO function,
set to "1 ".
The error is detected during the servo ON.
Input the STO signal after turning the servo
OFF.
The error is detected during the servo OFF. Remedy the wiring and signal for STO cable.

Check the wiring and setting environment.
1) Correctly grounded?
2) Any noise generating devices around the unit?
3) Are the speed/position encoder cables correctly
shielded?
1) The grounding is incomplete.
Correctly ground.

◯
2) The alarm occurs easily when a specific
device operates.
Use noise measures on the device described
on the left.
3) The cable is not correctly shielded.
Correctly shield the cable.
No abnormality is found in particular.
Replace the drive unit.
