When Jumper J1 is placed in the "TRQ" position, the drive will control motor torque as a
linear function of main potentiometer setting. If the motor load exceeds the torque
setting, the motor will stall, the Overload LED will light, and the drive will apply a constant
preset torque based on the potentiometer setting. The Overload LED will light when the
load torque approaches the current limit set point. The torque limits are set via jumper J4
and the CL trimpot.
