H54 Acceleration Time (Jogging)
H55 Deceleration Time (Jogging)
H54 and H55 specify the acceleration and deceleration times for jogging operation, respectively. The
acceleration time is the one required for accelerating from 0.00 to the maximum speed (r/min) and
the deceleration time, for decelerating from the maximum speed to 0.00 (r/min).
- Data setting range: 0.00 to 99.9 (s)
 For details, refer to function code C20.
H56 Deceleration Time for Forced to Decelerate
H56 specifies the deceleration time for forced deceleration. The deceleration time is the one required
for decelerating from the maximum speed to 0.00 (r/min).
- Data setting range: 0.00 to 99.9 (s)

Forced to decelerate
The DRS command can be assigned to a general-purpose, programmable input terminal by setting
"66." The DRS should be ON when the inverter is running. Turning the DRS OFF makes the inverter
decelerate with the deceleration time specified by H56 and then shuts down the inverter output when
reaching the stop speed.
Once the
DRS
goes OFF, the inverter no longer runs (that is, the forced-to-decelerate mode will not
be canceled) until the run command goes OFF and the inverter output is shut down. The operation
scheme is shown below.
