This parameter adjusts the rising time of motor torque at time of restarting. Adjust this parameter to
inertia moment of the load.

Note) Even if these functions are used, a motor may free run according to load conditions. In this case,
please use the auto restart function together.
Note) These functions do not operate at the time of torque control or position control.
Note) Usual slowdown time comes at the time of notes = and =.
The time for which the motor keeps running
varies with the inertial of the machine operated
and the loading conditions. So, conduct a test
to determine the time before using this function.
Using this function in conjunction with the retry
function enables the inverter to restart without
making a fault stop.
The power ride-through control ( = ) is
exercised for about 100 [ms]. (A inverter which
Applicable Motor capacity is 22kW or less is
able to continue to control the motor a few
seconds.)

Function
1) Regenerative power ride-through control
When instant electric power failure occurs during operation, this function makes
operation continue using the regeneration energy from a motor.
2)Deceleration stop
When instant electric power failure occurs during operation, this function stops the
motor quickly compulsorily. A forcible stop is carried out in (Deceleration
time) using the regeneration energy from the motor. (Deceleration time changes with
control.) After a compulsive stop, it maintains a stop state until operation instruction
is once turned off.
