5-2-5 Motor Fails to Operate
The Motor Does Not Operate when the RUN Key on the Digital
Operator is Pressed.
•Operation mode was not selected correctly.
Perform one of the following steps to enable the RUN Key on the Digital Operator.
Set “0” in n02.
If “1” is set in n02, set the local/remote changeover signal to ON. The local/remote
changeover signal can be switched using n08 (multi-function input selection 3).
•The reference frequency is too low.
When the reference frequency is less than 1.5 Hz, the Inverter cannot operate.
Change the reference frequency to 1.5 Hz or more.
The Motor Does not Operate when a Run Command is Input.
•Operation mode is selected incorrectly.
If “0” is set in n02, the motor does not operate even when a run command is input.
Set “1” in n02. If the local/remote changeover signal is set using n08 (multi-function
input selection 3), set the signal to OFF.
•The reference frequency is too low.
When the reference frequency is less than 1.5 Hz, the Inverter does not operate.
Change the reference frequency to 1.5 Hz or more.
The Motor Stops during Acceleration or when a Load is
