Using the /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 signal.

Status Conditions Description
ON
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 setting).
OFF
The circuit between CN1-1 and 2 is
open.
CN1-1 is at high level.
Servomotor output torque is not being limited.
(Internal torque reference is less than the limit
setting).
