Type Signal Connector Pin
No.
Signal Status Meaning
Input /P-CL Must be allo-
cated.
ON (closed) Applies the for-
ward external
torque limit. The
torque is limited
to the smaller of
the settings of
Pn402
*1
and
Pn404.
OFF (open) Cancels the for-
ward external
torque limit. The
torque is limited
to the setting of
Pn402
*1
.
Input /N-CL Must be allo-
cated.
ON (closed) Applies the
reverse external
torque limit. The
torque is limited
to the smaller of
the settings of
Pn403
*2
and
Pn405.
OFF (open) Cancels the
reverse external
torque limit. The
torque is limited
to the setting of
Pn403
*2
.
*1. Pn483 is used for a Linear Servomotor.
*2. Pn484 is used for a Linear Servomotor.
You must allocate the /P-CL and /N-CL signals to use them. You can use
the following parameters to allocate the signal to a terminal.
– Pn50B = n.  X  (/P-CL (Forward External Torque Limit Input)
Signal Allocation)
– Pn50B = n.X
 (/N-CL (Reverse External Torque Limit Input)
Signal Allocation)
Refer to the following section for details.
Ä Chap. 7.2.2 ‘Input Signal Allocations’ page 196
The parameters that are related to setting the torque limits are given below.
If the setting of Pn402 (Forward Torque Limit), Pn403 (Reverse Torque Limit), Pn404
(Forward External Torque Limit), or Pn405 (Reverse External Torque Limit) is too low, the
torque may be insufficient for acceleration or deceleration of the Servomotor.
