The signal shown on the right is output while torque is being restricted.
Note This function is changed to another function depending on the setting of bit 2 of
memory switch Cn-02 (see below).
To use input signals P-CL and N-CL as torque limit input signals, set the following
memory switch to 0.
Contact Input Speed Control
Cn-02 Bit 2
Selection
Prohibits the contact input speed control function.
If the contact input speed control function is used,
the contents of the input signals shown below will
change.
After this memory switch is reset, the meanings of the following signals will
also change:
Monitor mode (Un-05) bit 7 and bit 8
Setting Meaning
Does not use
the contact

function.
Uses the contact

control function.
Torque restriction applies during forward rotation.
Torque restriction does not apply during forward
rotation. Normal operation status.
Torque restriction applies during reverse rotation.
Torque restriction does not apply during reverse
rotation. Normal operation status.
