Preset Value: Cn-08 (TLMTF)
Cn-09 (TLMTR)
Cn-18 (CLMIF) : P-CL input only
Cn-19 (CLMIR) : N-CL input only
Note This function is changed to another function depending on the setting of bit 4 of
memory switch Cn-01.
To use output signals CLT+, CLT- as a torque limit output signal, set the following memory
switch to 0.
This memory switch can also be used to set level 2 torque restriction (described in the
next subsection).

Setting: 0
For Speed/Torque Control
Sets the output conditions for output signals CLT+ (1CN-25) and CLT- (1CN-26).
Setting Meaning
0
Uses CLT+, CLT- output signals as a torque
limit output signal.
Compares the DR2 Servopack internal torque
(current) reference with the preset value.
