The J3 connector is used to connect PMAC to the first 4 channels (Channels 1, 2, 3, and 4) of servo amps and encoders.

Note 1: In standalone applications, these lines can be used as +5V power supply inputs to power PMAC’s digital circuitry.

Note 2: Referenced to digital common (GND). Maximum of ±12V permitted between this signal and its complement.

Note 3: Leave this input floating if not used (i.e. digital single-ended encoders).

Note 4: ±10V, 10 mA max, referenced to common ground (GND).

Note 5: Leave floating if not used. Do not tie to GND.

Note 6: Functional polarity controlled by variable Ix25. Must be conducting to 0V (usually GND) to

produce a 0 in PMAC software. Automatic fault function can be disabled with Ix25.
