5-3-10 Torque limit of speed control mode
In speed mode, the motor torque limit input contact TLMT could be used to select one of the two methods
below:
(1) Internal toque limit: Using default Cn010 (CCW Torque command limit ) and
Cn011(CW Torque command limit ).
(2) External analog command: Using two separate analog voltage command signals at input terminals
PIC(CN1-27) to limit CCW torque and NIC(CN1-28) to limit CW torque.
As shown in the table below:

Please check 5-6-1 to set the required high /Low signal levels ( PNP/NPN) selection.
Caution!
To use external analog torque command limit , If analog torque command limit is greater than
internal torque command limit, the internal torque command limit has the priority over external
analog torque command limit.
Internal Torque command limit is set as below.
