3) How to Set Level 2: External Torque Limit

First, use a contact input signal to make the torque
(current) limit value set in the user constant valid.
Torque limit can be set separately for forward and
reverse rotation.
To use this function, always set bit 2 of memory
switch Cn-02 to 0 (standard setting). The contact
input speed control function cannot be used.
ON: 1CN-11 is at
low level.
P-CL P CL
OFF: 1CN-11 is at
high level.
ON: 1CN-12 is at
low level.
N-CL N CL
OFF: 1CN-12 is at
high level.
This torque restriction
function outputs the signal
shown on the right.
Examples of Use:
D Forced stopping
D Holding workpiece by robot
Sets a torque limit value when torque is restricted by external contact input.
This function is valid when bit 2 of memory switch Cn-02 is set to 0.
Torque restriction applies during forward rotation.
Torque restriction does not apply during forward
rotation.
Torque restriction applies during reverse rotation.
Torque restriction does not apply during reverse
rotation.
