Torque Mode Radio Button
Selecting this radio button will put your drive in Torque mode and activates the Full Scale
Torque and the Torque Limit data entry boxes. In Torque mode the drive develops torque in
proportion to the voltage received on the Analog Input. The Analog Input is scaled to the
Analog Torque Command by the Full Scale Torque, Analog Input Full Scale and Analog
Input Zero Offset parameters.

Pulse/Pulse Radio Button
Selecting this radio button puts your drive in Pulse/Pulse interpretation. In Pulse/Pulse mode,
pulses received on the A channel are interpreted as positive changes to the Pulse Position
Input, and pulses received on the B channel are interpreted as negative changes to the Pulse
Position Input.
Pulse/Direction Radio Button
Selecting this radio button puts your drive in Pulse/Direction interpretation. In Pulse
Direction mode, pulses are received on the A channel, and the direction is received on the B
channel. If the B is high, pulses received on the A are interpreted as positive changes to the
Pulse Position Input. If the B is low, pulses received on the A are interpreted as negative
changes to the Pulse Position Input.
Pulse/Quadrature Radio Button
Selecting this radio button puts your drive in Pulse/Quadrature interpretation. If Pulse
Quadrature is selected, a full quadrature encoder signal is used as the command. When B
leads A encoder counts received are interpreted positive changes to the Pulse Position Input.
When A leads B encoder counts received are interpreted as negative changes to the Pulse
Position Input. All edges of A and B are counted, therefore one revolution of a 2048 line
encoder will produce a 8192 count change on the Pulse Position Input.
