Using Contact Input Speed Control
Follow steps 1 to 3 below to use the contact input speed control function.
1. Set contact input speed control as shown below.
The speed can be controlled via contact inputs.
Meanings for the following signals change when the contact input speed control
function is used.
Note: 1. 0: OFF (high level); 1: ON (low level)
2. /P-CON, /P-CL and /N-CL functions differ from those in the table above when Pn000.1 is set to 3, 4, 5, or
6. The function is switched automatically when Pn50A. 0 is set to 0.
3. The /SPD-D, /SPD-A, and /SPD-B signals can be used only when signals are allocated to the input circuits.
See 5.3.3 Input Circuit Signal Allocation.
