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
.
