5.6 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.
5.6.1 Basic Settings for Speed Control with an Internal Set Speed
This section describes the basic settings for the internal set speeds.
(1) Signal Setting
The following input signals are used to switch the operating speed.
Factory-set Input Signal Allocations: /P-CON, /P-CL, and /N-CL
Changing Input Signal Allocations: /SPD-D, /SPD-A, and /SPD-B
(2) Parameter Setting
Select the speed control with an internal set speed with Pn000.1.
