Precautions for Correct Use
The status information displayed on the inverter in the event of an alarm may not match the
apparent operation of the motor.
For example, under PID control or in applications where the frequency is input via the analog
signal, the inverter may accelerate and decelerate slightly in a repetitive manner due to fluctua-
tion of the analog signal etc. even though the motor may appear to rotate at a constant speed.
The inverter in a trip state can be reset in either of the following two methods.
•
Press the STOP/RESET key on the Digital Operator.
This key can be used to reset a trip error when the STOP Key Selection (b087) is set to 00 (Enabled)
or 02 (Only resetting enabled).
•
Input the reset signal via the control circuit terminal block.
Set one of the Multi-function Input 1 to 7 Selection (C001 to C007) to 18 (RS: Reset).
The above reset methods may not be effective depending on the trip factor.
In such cases, cycle the power supply.
