Description of Warning Codes
‑20‑
Cause
Confirming Method
Solution
The homing method value is
too large.
Check the homing method
value (object dictionary
6098h).
Change the value of 6098h.
● E631.4: P‑Mos short‑circuited
Cause:
The brake circuit is faulty.
Cause
Confirming Method
Solution
When braking is used, the P‑
MOS short 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. Replace the servo drive.
2. Turn off the brake switch
H02.16.
● E631.5: N‑Mos short‑circuited
Cause:
The brake circuit is faulty.
Cause
Confirming Method
Solution
When braking is used, the N‑
MOS short 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. Replace the servo drive.
2. Turn off the brake switch
H02.16.
● E730.0: Encoder battery warning
Cause:
The voltage of the absolute encoder battery is lower than 3.0 V.
Cause
Confirming Method Solution
The voltage of the absolute
encoder battery is lower
than 3.0 V.
Measure the battery voltage.
Use a new battery with the
matching voltage.
Note
E731.0 and E733.0 can trigger E730.0. See E731.0 and E733.0 for other solutions.
● E730.1: Inovance 2nd encoder battery voltage low
Cause:
Inovance 2nd encoder battery voltage is lower than 3.0 V.
Cause
Confirming Method
Solution
Inovance 2nd encoder
battery voltage is too low.
Measure the battery voltage.
Use a new battery with the
matching voltage.
