Amplifier Connection (Brush DC Motor or Motor Commutated by the
Amplifier)
PMAC-Pack interfaces to the system amplifiers through the "SERVO" port. Pinouts are shown in Figure
2-3. Each Axis has a SERVO port which serves to communicate amplifier command signals (Torque or
Velocity), the amplifier enable signal, and amplifier fault signal. If PMAC is not performing the
commutation for the motor, only one analog output channel is required to command the motor. This
output channel can be either single-ended or differential, depending on what the amplifier is expecting.
Single-Ended Command Signal
For a single-ended command using PMAC channel 1, connect DAC1 (pin 5) to the command input on the
amplifier. Connect the amplifier's command signal return line to PMAC's AGND line (pin 4).
Note:
In this setup, leave the DAC1/ pin (pin 6) floating; do not ground it.
Differential Command Signal
For a differential command using PMAC channel 1, connect DAC1 (pin 5) to the plus-command input on
the amplifier. Connect DAC1/ (pin 6) to the minus command input on the amplifier. PMAC's AGND (pin
4) should still be connected to the amplifier common.

Amplifier Enable Signal (AENA/)
Most amplifiers have an enable/disable input that permits complete shutdown of the amplifier regardless
of the voltage of the command signal. PMAC's AENA/line is meant for this purpose. AENA/ is pin3. This
signal is an open collector output with internal 3.3K pull up resistor to 15Vdc and requires a pull up
resistor. For early tests, you may wish to have this amplifier signal under manual control. The polarity of
the signal is controlled by PMAC-Lite jumper(s) E17. The default is low-true (conducting) enable, which
is the safest polarity because a PMAC shutdown will automatically disable the amplifiers.
