11. Protection Functions

To improve reliability, the drive incorporates some built-in protections features.

Priority

Time(s) of

Blink

Sequence wave of red LED

Description

1st

Over-current protection activated when peak
current exceeds the limit.

2nd

Over-voltage protection activated when drive
working voltage is greater than 60VDC

3nd

Reserved.

When above protections are active, the motor shaft will be free or the red LED blinks. Reset the drive by repowering it
to make it function properly after removing above problems.
