3.3 LED Light Indication
There are two LED lights for DM56-CAN. The GREEN one is the power indicator which will be always on generally. The
RED one is a protection indicator which will flash 1-2 times in a 3-second period, when protection enabled for a
EM522-CAN. Different number of flashes indicates different protection type ,as shown following table.
Priority

Description
1st
1
Over-current protection activated when peak
current exceeds the limit.
2nd
2
Over-voltage protection activated when drive
working voltage is greater than 90VDC
3rd
8
EEPROM Fault(need to configure parameter )
4th
12
Operational Amplifier Fault (need to configure
parameter )
!
Notice
Notes:
(1) The protections for detecting
.fault of EEPROM fault and Operational Amplifier need to turn on manually
via configuring parameter, read section 4.4 for detail; (2) When one of the protection is active, the motor shaft will be free
and the red LED blinks. Restart the power to make it function properly after removing above problems.
