6.6.1 Starting frequency
 : Starting frequency
 Function
The frequency set with  is put out as soon as operation is started.
Use the  parameter when a delay in response of starting torque according to the
acceleration/deceleration time is probably affecting operation. Setting the starting frequency to a
value from 0.5 to 3Hz is recommended. The occurrence of an overcurrent can be suppressed by
setting this frequency below the rated slippage of the motor.

 Function
The Run/stop of operation can be controlled simply with frequency setting signals.

When the frequency command signal
reaches the B point, the inverter
operates.
When decelerating, operation stops
when the frequency setting signal is less
than point A.
