Alarm Code 95H (Encoder BUSY error)
This is an error detected at receiving section of absolute position detector in start-stop
synchronization.
Operating state when alarm occurred
Possible causes
Operating state

When control power supply is turned on Low High High
Corrective measures
Cause Corrective measures
1 Faulty encoder
Replace servo motor
2 Malfunction due to noise
Check if amplifier earth cable should
be correctly grounded. Check shielding
procedure of encoder cable. Add ferrite
core as a countermeasure against
noise.
3 Incorrect encoder wiring
Review the wiring between encoder
and amplifier

Alarm Code A3H (Encoder overheat)
This is an error detected at receiving section of absolute position detector in start-stop
synchronization.

Corrective measures
Cause Corrective measures
1 Faulty encoder internal circuit Replace servo motor
2
Though motor itself does not
overheat, ambient temperature of
sensor is too high.
Review the cooling method and keep
the encoder ambient temperature
below
3 Motor overheat
Review the cooling method of
servomotor.
