PMAC Reset
Low is Reset. See note 11
Note
Note 8:
Pins marked
PLIMn
should be connected to switches at
the
positive
end of travel. Pins marked
MLIMn
should be
connected to switches at the
negative
end of travel.
Note 9
: Must be conducting to 0V (usually GND) for PMAC to
consider itself not into this limit. Automatic limit function can
be disabled with Ixx24.
Note 10
: Functional polarity for homing or other trigger use of
HOMEn controlled by Encoder/Flag Variable I70n2. HMFLn
selected for trigger by Encoder/Flag Variable I70n3. Must be
conducting to 0V (usually GND) to produce a 0 in PMAC
software.
Note 11
: Even if it is not used but connected, long cabling may
pull this line low and cause PMAC to unintentionally reset.

Overtravel Limits and Home Switches
When assigned for the dedicated uses, these signals provide important safety and accuracy functions.
PLIMn and MLIMn are direction-sensitive over-travel limits that must conduct current to permit motion
in that direction. If no over-travel switches will be connected to a particular motor, this feature must be
disabled in the software setup through the PMAC Ixx24 variable.
Wiring the Limits and Flags
PMAC expects a closed-to-ground connection for the limits to not be considered on fault. This
arrangement provides a failsafe condition. Usually, a passive normally close switch is used. If a
proximity switch is needed instead, use a 5 to 24V normally closed to ground NPN sinking type sensor.
