Trip
code
Trip Type
Possible causes
Solutions
inverter direction.
LC
Fast current limit
fault
1. Load too large or
motor blocked to
stall
2. Inverter power
rating too small
3. Inverter output
circuit loop
grounded or SC.
1. Decrease the load and
check motor and mechanical
part status
2. Choose higher power
inverter
3. Remove the external fault
EF2
Terminal close
fault
1. The FWD or REV
terminals close and
get power on. But
inverter is set to not
allow the restart
after power failure
recovery.
1. Disconnect the FWD or
REV terminal first and then
power on the inverter.
2. Close the fault detection
function for closed terminal
fault (FC.11=0)
PIDE
PID feedback
error
1.
PID
feedback
offline
1. Check PID feedback line.
2. Disable PID feedback
detection (F8.24=0.0%)
3. Increase PID feedback
offline detection time (F8.25)
OLP2
Overload
pre-alarm error
1.fequency inverter
output current is
higher than set
pre-alarm threshold
1. Disable pre-alarm
function(FC.19=0)
2. Increase pre-alarm
threshold value (FC.02)
3. Increase pre-alarm
detection time(FC.03)
