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 the servomotor output torque (current) is
being limited.

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).
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.

Note: Multiple signals allocated to the same output circuit are output using OR logic. Set other output signals to a
value other than the one allocated to the /CLT signal in order to use just the /CLT output signal. See 5.3.4
Output Circuit Signal Allocation.
