LCD Display
Description
output terminals or relay (OUT-31–35 or OUT-36) to ‗35
(FanExChange)‘ to receive the fan replacement warning output
signals.
Low Battery
Displayed when the RTC battery voltage drops to or below 2 V. To
receive a warning output signal, set PRT-90 (Low Battery) to ‗Yes‘.
Broken Belt
Displayed when PRT-91 is set to warning and the inverter becomes
on the condition of broken belt.
Load Tune
Displayed when the values of ‗AP2-03 and AP2-04‘ are more than
the values of ‗AP2-09 and AP2-10‘ and the function of load tunning
is not normal.
PareWrite Fail
Displayed when the function of smart copier is not normal.
Rs Tune Err
Displayed when the function of Rs tunning is not normal . For
example, auto tunning is performed without wiring the motor.
Lsig Tune Err
Displayed when the function of Lsigma tunning is not normal . For
example, auto tunning is performed without wiring the motor.
9.2 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.
The inverter load is greater than the
rated capacity.
Replace the inverter with a model
that has increased capacity.
