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.
