• 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
