If PID is performed while the operation is started when [AH-75] PID soft-start function selection and
[AH-81] PID start abnormal judgment implement selection are set to 01, this error occurs when the PID
feedback value does not reach [AH-82] PID start abnormality judgment level after the elapse of [AH-80]
soft-start time.
E107 Over-speed Error
Occurrence Estimated cause(s) Exemplar measures to be taken
Error occurred
during operation.
Recheck the setting of
electronic gear. Re-examination of operation condition or correction of load
condition may improve the situation.
Improper encoder setting Check the setting of encoder constant and the like.

Error occurred
during operation.
The target value is too
low. Re-examination of [AH-76] PID soft-start target level may
improve the situation.
Wires are disconnected.
Input PID feedback data may not be appropriate. Check the
wiring and [db-44] PID1 feedback monitor.
