Pin-Out Description for DMC-1700/1800

Outputs
Analog Motor Command	+/- 10 Volt range signal for driving amplifier. In servo mode, motor
	command output is updated at the controller sample rate. In the motor
	off mode, this output is held at the OF command level.
Amp Enable	Signal to disable and enable an amplifier. Amp Enable goes low on
	Abort and OE1.
PWM/STEP OUT	PWM/STEP OUT is used for directly driving power bridges for DC
	servo motors or for driving step motor amplifiers. For servo motors: If
	you are using a conventional amplifier that accepts a +/-10 Volt analog
	signal, this pin is not used and should be left open. The PWM output is
	available in two formats: Inverter and Sign Magnitude. In the Inverter
	mode, the PWM (25kHz) signal is .2% duty cycle for full negative
	voltage, 50% for 0 Voltage and 99.8% for full positive voltage (25kHz
	Switching Frequency). In the Sign Magnitude Mode (Jumper SM), the
	PWM (50 kHz) signal is 0% for 0 Voltage, 99.6% for full voltage and
	the sign of the Motor Command is available at the sign output (50kHz
	Switching Frequency).
