Internal Set Speed Control

This section describes operation using speed control with the internal set speeds.
This function enables an operation to be executed at a controlled speed. The speed, direction, or both are
selected in accordance with a combination of input signals from an external source. Servomotor speed settings
are made beforehand using the parameters in the SERVOPACK. Because the speed is controlled with a param-
eter in the SERVOPACK, an external pulse generator or a reference generator that controls speed is not
needed.

When using the external input signal pins as factory settings, the functions of /P-CON, /P-CL, and /N-CL change to the
functions of /SPD-D, /SPD-A, and /SPD-B, respectively.
