Note: Set these parameters so that the start frequency H is higher than the stop frequency H .
If the H -set frequency is lower than the H -set frequency, the reference frequency must be
higher than the H-set frequency to start the motor.
If both H and H are set to Hz, the motor will start even if the frequency set is 0.0Hz.

Function
The frequency set with the parameter 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 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 (RV=,
), set H, H at 0.0Hz.
• At start up : frequency set with H is put out immediately.
• At stop : The output frequency drops to 0Hz immediately by the frequency set with
H.
