6.7.1 Start frequency/Stop frequency
: Start frequency setting
: Stop frequency setting
• Function
The frequency set with the parameter 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 2.0Hz (max. 5Hz) is recommended. The occurrence of an overcurrent can be suppressed by setting
this frequency below the rated slippage of the motor. If 0 speed torque is needed ( = ), set ,
at 0.0Hz.
