Consider the following changes to tune/improve the performance of the drive/system.

8.1  Torque Control Mode

The drive can control the torque (current) of the motor, instead of the speed (volts), by 

allowing an external input to clamp the current demand. NOTE: The speed loop then 

provides the current demand, and hence the speed loop must always be asking for more 

current than the clamp level. This technique gives automatic over-speed limiting.

Establish the correct operating limits by commissioning first in speed mode. Then implement 

torque control by moving the SPEED / 2Q / 4Q link from SPEED to the required TORQUE 

position (2Q or 4Q) and apply an appropriate torque control voltage to T6.

TORQUE/SPEED JUMPER:

 

This is a 3-position jumper controlling the function of Terminal 6 

(AUX). A schematic is shown below:

The 2Q TORQUE 

clamp operates in 1Q 

and 2Q on the positive 

current only.
The 4Q TORQUE 

clamp operates in 

all 4 quadrants on 

positive and negative 

currents.
The 4Q TORQUE mode 

can be used for load 

sharing by inputting 

the modulus current 

signal from SP69 on a 

master drive.
