Err03
Over-current
during
deceleration
1. The main circuit
output is grounded or
short circuited.
2. Motor auto-tuning is
performed improperly.
3. The load is too
heavy.
4. The deceleration
rate is too short.
5. The encoder signal
is incorrect.
8. Check whether the balance
coefficient is correct.
9. Check whether the encoder
wirings are correct. For
asynchronous motor, perform
SFVC and compare the current to
judge whether the encoder works
properly.
10. Check:
•
Whether encoder pulses per
revolution (PPR) is set correctly
•
Whether the encoder signal is
interfered with
•
Whether the encoder cable runs
through the duct independently
•
Whether the cable is too long
•
Whether the shield is grounded
at one end
•
11. Check whether:
•
Whether the encoder is installed
reliably
•
Whether the rotating shaft is
connected to the motor shaft
reliably
•
Whether the encoder is stable
during normal-speed running
12. Check whether UPS feedback
is valid in the non-UPS running
state (Err02).
13. Check whether the acceleration/
deceleration rate is too high (Err02,
Err03).
(End)

Err04
Over-current at
constant speed
1. The main circuit
output is grounded or
short circuited.
2. Motor auto-tuning is
performed properly.
3. The load is too
heavy.
4. The encoder is
seriously interfered
with.
