3.4 TORQUE/SPEED ANALOG OUTPUTS
Torque and Speed DAC Outputs provide an analog output proportional to the torque and speed of
the system. They are available on the Accessory Torque-Speed Output Connector (as seen in Figure
2–6 Accessory Torque-Speed Output) and are updated every 2 milliseconds. Both of the outputs
have a user definable Scale Factor found under the SHIFT/AUX SETUP key sequence.
3.4.1 torqUe DaC SCaLe faCtor
Torque DAC Scale Factor is scaled in displayed torque units/volt.
Example:
If the displayed torque units are set to oz.in. and the Torque DAC scale is set to 1 unit/volt,
then 1 oz.in. will result in 1 volt at the torque output.
3.4.2 SpeeD DaC SCaLe faCtor
Speed DAC Scale Factor is scaled in rpm/volt.
Example:
If the Speed DAC scale is set to 1000 rpm/volt, then 1000 rpm will result in 1 volt at the
speed output.
