Motor-driven outputs are intended to drive conventional motors. These outputs
can deliver several amps of current. The outputs use PWM for speed control. The
output voltage values must be -6 to +6 VDC or -12 to +12 VDC. Speed is controlled
by varying the duty cycle of the output. Since the outputs are PWM, you should
evaluate performance with an oscilloscope, not a digital voltmeter.
