5.To repeat the tests for negative (reverse) demands, type:

TORQUE.4=-5

This should cause a demand of -5% of maximum output (-0.5V) to be produced at the DEMAND0 output. Correspondingly, the Spy window’s Velocity display should show a negative value.

6.To remove the demand and stop the test, type:

STOP.4

This should cause the demand produced at the DEMAND0 output to become 0V.

If it is necessary for the motor to turn in the opposite direction for a positive demand, then the DACMODE and ENCODERMODE keywords should be used. The DACMODE keyword can be used to invert the demand output voltage. The ENCODERMODE keyword must also be used to reverse the incoming feedback signal, to correspond with the inverted demand output. Note that if ENCODERMODE had already been used to compensate for a reversed encoder count (as described in step 4. above), it will be necessary to change it back to its original setting to correspond with the inverted demand output set using DACMODE. See the MintMT help file for details of each keyword.
