Description of Fault Codes
‑63‑
Cause:
The brake circuit is faulty.
Cause
Confirming Method
Solution
When braking is used, P‑
MOS open circuit occurred
on the brake circuit.
Ensure the brake cable is
connected, check if the fault
persists after the servo drive
is powered off and on again.
1. Turn off the brake switch
H02.16.
2. Replace the motor.
● E631.3: N‑MOS open circuit
Cause:
The brake circuit is faulty.
Cause
Confirming Method
Solution
When braking is used, N‑
MOS open circuit occurred
on the brake circuit.
Ensure the brake cable is
connected, check if the fault
persists after the servo drive
is powered off and on again.
1. Turn off the brake switch
H02.16.
2. Replace the motor.
● E631.4: P‑Mos short‑circuited
Cause:
The brake circuit is faulty.
Cause
Confirming Method
Solution
The P‑Mos is short‑circuited.
Ensure the brake cable is
connected, check if the fault
persists after the servo drive
is powered off and on again.
Replace the servo drive.
● E631.5: N‑Mos short‑circuited
Cause:
The brake circuit is faulty.
Cause
Confirming Method
Solution
The N‑Mos is short‑circuited.
Ensure the brake cable is
connected, check if the fault
persists after the servo drive
is powered off and on again.
Replace the servo drive.
● E640.0: IGBT junction temperature too high
Cause:
The IGBT junction temperature reaches the fault threshold defined by H0A.18.
