Programming 130

Torque limit is activated in both the speed and torque control when operating in open loop vector or flux vector control methods

(A1-02 = 2 or 3). If the multi-function analog input is programmed for “10: Forward Torque Limit”, “11: Reverse Torque

Limit”, “12: Regen Torque Limit”, or “15: FWD/REV Torque Limit”, the Drive uses the lower value of either L7-0x or analog

input torque limit.

Fig. 94 Torque Limit - 4 Quadrant Operation

The following block diagram shows the relationship between torque limit using parameter settings and torque limit using multi-

function analog inputs.
