6.7.1 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.

When the frequency command signal
reaches the B point, the invert er
