Jon,

Not to change the subject but does this amplifier specification appear to be
fully compatable with your pwm controller ?

It looks like it probably would work. One area of concern is the
100 Ohm current limit resistors. That might require about 34 mA
of drive, which seems excessive. Also, the + of the opto input is
tied to +5 V. The PWM controller drives the output high for ON,
not low. I guess you could put an inverter between the PWM controller
and the servo amp.

On the other hand, we make our own servo amps for brush and brushless
motors, and they are pretty inexpensive, and rated for higher voltage than
these AMC amps.
