IDE Hall
current
detection
fault
1. The current
sensoring or hall
device get damaged.
1. Ask for service from
supplier
ECE ③
Encoder
fault
1. Encoder signal
wires are connected
reversely.
1. Check whether the
encoder signal is correctly
connected.
2. Encoder signal
wires get damaged.
2. Check whether the
encoder wiring is broke.
3. Encoder damaged. 3. Change the encoder.
4. Dual-way encoder
detected motor
direction is not match
with drive direction.
4. Change the encoder
direction (F3.16) or alter
motor wiring sequence.

current limit
fault
1. Load too large or
motor blocked to stall
2. Drive power rating
too small
3. Drive output circuit
loop grounded or SC.
1. Decrease the load and
check motor and mechanical
part status
2. Choose higher power drive
3. Remove the external fault
EF2
Terminal
close fault
1. The FWD or REV
terminals close and
get power on. But
drive is set to not
allow the restart after
power failure
recovery.
1. Disconnect the FWD or
REV terminal first and then
power on the drive.
2. Close the fault detection
function for closed terminal
fault (FC.11=0)
