Description
Auto Tuning and no signal is input during the encoder test.
Signals are released if ENC Tune is set among the functions of
OUT31~33.
Enc Dir Check An alarm is signified if No. 3 Enc Test is selected from BAS-20
Auto Tuning and the setting is wrongly changed between
encoder phase A and B during the encoder test or the rotation
direction is reverse. Signals are released if ENC Dir is set among
the functions of OUT31~33.
Lost Keypad An alarm is signified if the operating command is keypad or any
problem is detected with the communication between the keypad
and the main body of the inverter in Keypad JOG Mode with
PRT-11 Lost KPD Mode set 0. As the output signal, No. 29 Lost
Keypad is selected among the functions of OUT31~33.
Check Line PLZ An alarm is signified if the communication error is detected
between Control CPU and Keypad. It might be occurred from the

4.2 Troubleshooting Fault Trips
When a fault trip or warning occurs due to a protection function, refer to the following table
for possible causes and remedies.
Type
Cause
Remedy
Over Load
The load is greater than the motor’s
rated capacity.
Ensure that the motor and inverter
have appropriate capacity ratings.
The set value for the overload trip level
(PRT-21) is too low.
Increase the set value for the
overload trip level.
Under Load
There is a motor-load connection
problem.
Replace the motor and inverter with
models with lower capacity.
The set value for underload level (PRT-
24) is less than the system’s minimum
load.
Reduce the set value for the
underload level.
Over
Current1
Acc/Dec time is too short, compared to
load inertia (GD
2
).
Increase Acc/Dec time.
