Setting Level 2: External Torque Limit
A contact input signal is used to enable the torque (current) limits 
previously set in parameters. Torque limits can be set separately for 
forward and reverse rotation.

This is the external torque (current) limit input for forward and reverse 
rotation. 
Check input signal allocation status when using this function (see 5.3.3 
Input Circuit Signal Allocation). Default settings are given in the table

Description
CN1-45 at low level when ON
Use forward torque limit.
Limit: Pn404
/P-CL
CN1-45 at high level when OFF
Do not use forward torque 
limit. Normal operation. 
—
CN1-46 at low level when ON
Use reverse torque limit.
Limit: Pn405
/N-CL
CN1-46 at high level when OFF
Do not use reverse torque 
limit. Normal operation.
