The Motor Resistance is the factory default motor compensation. Typical programmed value is .05 Ohms. •
The Motor Voltage for each motor should increase evenly. •
If the voltage is not even, verify that a Veer Compensation has not been programmed into the chair. •
If the Motor Voltages are still not even, the Motor Controller may be defective. Verify that there are no faults •
recorded in the Fault section of the Quickie iQ or HHP.
The Motor Current should be even for both motors when the Motor Voltages are equal. A typical value for •
the Rhythm or Groove motors with the gear box disengaged is 4 to 6 amps. Cold motors may indicate higher
current.
Excessive current may be caused by bad bearings, defective or shorted motor windings, or a dragging park •
brake.
The Motor RPM should be even for both motors when the Motor Voltages are equal. •
If the Motor RPMs are not equal and the wheelchair contains IntelliDrive, suspect a bad motor encoder or •
motor controller.
