Using /CLT Signal
The following section describes the use of the contact output signal /CLT as a torque limit
output signal.
This signal indicates whether servomotor output torque (current) is being limited.
Settings: Pn402 (Forward Torque Limit)
Pn403 (Reverse Torque Limit)
Pn404 (Forward External Torque Limit): /P-CL input only
Pn405 (Reverse External Torque Limit): /N-CL input only
When the /CLT signal is used, the following parameter must be used to select the output sig-
nal.

ON Status The circuit between CN1-
*1 and *2 is closed.
CN1-*1 is at low level. Servomotor output torque is being limited.
(Internal torque reference is greater than the limit set-
ting.)
OFF Status The circuit between CN1-
*1 and *2 is opened.
CN1-*1 is at high level. Servomotor output torque is not being limited.
(Internal torque reference is less than the limit setting.)
