The J8 connector is used to connect PMAC to the first 4 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 your 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.
