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: I
f
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).
