Internal Set Speed Control

You can set motor speeds in three parameters in the SERVOPACK and then perform speed
control by using external input signals to select the motor speed and direction. Because the
speed is controlled with parameters in the SERVOPACK, an external pulse generator or a refer-
ence generator is not required to control the speed.

Note: You must allocate the /SPD-D, /SPD-A, and /SPD-B signals to use them. You can use the following parame-
ters to allocate the signal to a terminal.
