(6) Command speed acceleration time, Command speed deceleration
time
Set the acceleration time for the speed to increase from "0" to reach the speed
limit value at speed-torque control and deceleration time taken to stop from the
speed limit value at speed-torque control during speed control or continuous
operation to torque control.

The command value to the servo amplifier is stored
at the command speed (#8004+20n, #8005+20n).
When the rotation direction is changed due to the command speed change
during speed control, the operation is as follows.
• A deceleration is made to 0 [r/min] according to the setting value of command
speed deceleration time. After that, an acceleration is made to the command
speed according to the setting value of command speed acceleration time.
