6.11 Operation frequency
6.11.1 Starting frequency/ Stop frequency
f240 : Starting frequency
f243 : Stop frequency setting
Function
The frequency set with is put out instantly when operation is started.
Use the parameter when a delay in response of starting torque due to the
acceleration/deceleration time may affect the operation. Setting the starting frequency to a value from
0.5 to 3.0Hz is recommended. The occurrence of an overcurrent can be avoided by setting this
frequency below the rated slippage of the motor.
When starting: Frequency set with f240 is output instantly.
When stopping: Output frequency turns to be 0Hz instantly with the frequency set with f243.

Title Function Adjustment range Default setting
f240
Starting frequency 0.1-10.0 (Hz) 0.5
f243
Stop frequency setting
0.0: Same as f240
0.1-30.0 (Hz)
0.0
Note: Set these parameters so that the starting frequency f240 is higher than the stopping frequency f243.
If the f240–set frequency is lower than the f243–set frequency, the inverter doesn’t start when the
frequency command is f243–set frequency or less.
