Note 1: 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 2: Must be conducting to 0V (usually GND) for PMAC to consider itself not into this limit. Automatic limit function can be disabled with Ix25.

Note 3: Functional polarity for homing or other trigger use of HOMEn controlled by Encoder/Flag Variable I9n2. HMFLn selected for trigger by Encoder/Flag Variable I9n3. Must be conducting to 0V (usually GND) to produce a 0 in PMAC software.
