Because of the true 4 quadrant method of output switching,
the output switches will PWM between the ICOMMAND POSITIVE
and ICOMMAND NEGATIVE states, with the average percentage
based on ICOMMAND being a positive voltage and a negative
voltage. With a zero voltage ICOMMAND, the output switches will
modulate with exactly a 50% duty cycle between the
ICOMMAND POSITIVE and ICOMMAND NEGATIVE states.
