The J8 connector is used to connect PMAC to the first four channels (Channels 1, 2, 3, and 4) of servo
amps, flags, and encoders.
Note 1:
In standalone applications, these lines can be used as +5V power supply inputs to power PMAC's
digital circuitry. However, if a terminal block is available on a version of PMAC, it is preferable to bring
the +5V power in through the terminal block.
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). In this case, jumper (E18
- 21, E24 - 27) for channel should hold input at 2.5V.
Note 4:
+ 10V, 10mA max, referenced to analog common (AGND).
Note 5:
Leave floating if not used. Do not tie to AGND. In this case, AGND is the return line.
Note 6:
Functional polarity controlled by jumper(s) E17. Choice between AENA and DIR use controlled
by Ix02 and Ix25.
Note 7:
Functional polarity controlled by variable Ix25. Must be conducting to 0V (usually AGND) to
produce a '0' in PMAC software. Automatic fault function can be disabled with Ix25.
Note 8:
Pins marked
-LIMn
should be connected to switches at the positive end of travel. Pins marked
+LIMn
should be connected to switches at the negative end of travel.
Note 9:
Must be conducting to 0V (usually AGND) for PMAC to consider itself not into this limit.
Automatic limit function can be disabled with Ix25.
Note 10:
Functional polarity for homing or other trigger use of HMFLn controlled by Encoder/Flag
Variable 2 (I902, I907, etc.) HMFLn selected for trigger by Encoder/Flag Variable 3 (I903, I908, etc.).
Must be conducting to 0V (usually AGND) to produce a '0' in PMAC software.
