6.6 Operation frequency
6.6.1 Starting frequency
H : Starting frequency setting
• Function
The frequency set with H is put out as soon as operation is started.
Use the H 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.

6.6.2 Run/stop control with frequency setting signals
H : Operation starting frequency
H : Operation starting frequency hysteresis
• Function
The Run/stop of operation can be controlled simply with frequency setting signals.

the frequency setting signal has reached
point B.
Deceleration begins when the frequency
setting signal decreases below point A.
