Control
In the Servopack, a speed reference is multiplied
by the preset acceleration or deceleration value to
provide speed control.
When a progressive speed reference is input or
contact input speed control is used, smooth
speed control can be performed. (For normal
speed control, set “0” in each parameter.)
Set the following value in each parameter.
• Cn-07: Time interval from the time the motor starts until it reaches the maximum speed*
• Cn-23: Time interval from the time the motor is running at the maximum speed* until it
stops
* : The maximum speed
