Torque Limit in Position, Speed and Fully-Closed Controls
For the torque limit in torque control, always select No. 1 Torque Limit (Pn013).
The torque limit under torque feed-forward selection is enable only during speed control when the
set value is 1 to 3.
PCL signal is assigned to the terminal 16 in CN1. For details, refer to “Torque Command Input 2
(TREF2) and Forward Torque Limit Input (PCL)” (P. 3-37).
NCL signal is assigned to the terminal 18 in CN1. For details, refer to "Reverse Torque Limit Input
(NCL)" (P. 3-37).
Pn521 set
value
Explanation
0
Forward operation: Set by PCL (0 to 10 V)
Reverse operation: Set by NCL (−10 to 0 V)
1 Limit in both forward and reverse operation: Set by Pn013
2
Forward operation: Set by Pn013
Reverse operation: Set by Pn522
