4.2 Soft Startup/Shutdown Time
When the controller starts from stop , the motor speed can be gradually increased
to the set value to prevent the motor and the controller from being impacted.
Soft Startup Time (t): When the controller starts from the stopped state, the time
required for the motor speed to smoothly increase from 0 to the set speed is called
the soft startup time.

When the controller is stopped from the running state, the motor speed
can be gradually reduced to 0 to prevent the motor and controller from
being impacted.
Soft Shutdown Time ( ): When the controller stops from the running
state, the time required for the motor speed to smoothly decrease from
the set value to 0 is called the soft shutdown time.
The operation method and parameter range of the soft shutdown time are
consistent with the soft startup time.
