• Using /CLT Signal
This section describes how to use contact output signal /CLT as a torque limit output sig-
nal.

Torque Limit Output For Speed/Torque
Control and
Position Control
This signal indicates whether motor output torque (current) is being restricted.
ON status: The circuit between 1CN-*1
and 1CN-*2 is closed.
1CN-*1 is at low level.
Motor output torque is being restricted.
(Internal torque reference is greater than the
preset value.)
OFF status: The circuit between 1CN-*1
and 1CN-*2 is open.
1CN-*1 is at high level.
Motor output torque is not being restricted.
(Internal torque reference is equal to or below
the preset value.)
Preset Value: Cn-08 (TLMTF)
Cn-09 (TLMTR)
Cn-18 (CLMIF) : P-CL input only
Cn-19 (CLMIR) : N-CL input only
