6.6 Operation frequency
6.6.1 Starting frequency
: Starting frequency setting
• 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.

The inverter begins accelerating after
the frequency setting signal has reached
point B.
Deceleration begins when the frequency
setting signal decreases below point A.
