• Using /P-CL and /N-CL Signals
This section describes how to use input signals /P-CL and /N-CL as torque limit input sig-
nals.

1CN-45
1CN-46

/P-CL
/N-CL
→ Input /P-CL 1CN-45
Forward External Torque Limit
Input (Speed Selection 1)
For Speed/Torque
Control and
Position Control
→ Input /N-CL 1CN-46
Reverse External Torque Limit
Input (Speed Selection 2)
For Speed/Torque
Control and
Position Control
These signals are for forward and reverse exter-
nal torque (current) limit input.
This function is useful in forced stopping.
P CL
ON: 1CN-45 is at
low level.
Torque restriction applies during forward rotation. Limit value:
Cn-18
P-CL
OFF: 1CN-45 is at
high level.
Torque restriction does not apply during forward
rotation. Normal operation status.
N CL
ON: 1CN-46 is at
low level.
Torque restriction applies during reverse rotation. Limit value:
Cn-19
N-CL
OFF: 1CN-46 is at
high level.
Torque restriction does not apply during reverse
rotation. Normal operation status.
The signal shown on the above are output while torque is being restricted.
Note This function is changed to another function depending on the setting of memory
switch Cn-2B (see below).
