6. 7. 1 Setting the starting frequency and the end
frequency
<F240: Start frequency>
<F243: End frequency>
■ Function
The frequency set for <F240: Start frequency> is instantly output at startup.
This parameter is used when the delayed response of starting torque caused by the acceleration/
deceleration time affects the frequency.
When the output frequency is decreased to the frequency set for <F243: End frequency>, the
frequency instantly becomes 0 Hz when stopping.
■ Parameter setting
■ Setting method
Use the parameters when the delayed response of starting torque caused by the acceleration/
deceleration time affects the frequency. For the setting values, 0.1-3.0 Hz (5 Hz or less) is
recommended. Overcurrent can be reduced by setting the value to the motor rated slippage or less.
Set the values so that <F240: Start frequency> is higher than <F243: End frequency>.
When <F240> is lower than <F243>, no operation is performed by any frequency command lower
than <F243>.
