Setting up a Homing Search Move

To do a homing search move, first check your position-capture I-variables (I902 and I903 in our
example). Make sure they are set up to capture the position where you want your home position. With a
bare motor, we can probably only use the third channel of the encoder. Set I902 to 1 to force a capture on
the rising edge of the third channel.

Next, set your homing speed with I123 (in units of counts/millisecond). Changing the sign of I123
changes the direction of the homing move. Homing accel/decel is controlled by I120 and I121 (which also
affect jog moves). Now you can command a homing move with the

HM

command, and the motor will

move as specified until the proper signal edge(s) is found, then decelerate to a stop and come back to the
position of the trigger, plus or minus an offset amount determined by I126.

Connecting Machine I/O

Caution:

PMAC-Pack is designed such that you never need to change jumpers on the
PMAC card to configure I/O as sinking or sourcing. Jumpers E1, E2 , and E7 on
the PMAC-Lite Card should never be changed from pins 1-2.

PMAC-Pack’s JOPT INPUT and JOPT OUTPUT connectors provide eight general-purpose digital inputs
and eight general purpose digital outputs. Each I/O point is opto-isolated and designed for direct
connection to 12 to 24V I/O.

For basic familiarization with PMAC-Pack’s machine I/O, you can use a 2- position switch and an LED,
moving on to actual I/O connection when satisfied that you can control their logic.

General Purpose Digital Outputs

Sinking Outputs (Standard)

Caution:

As default, E4 and E5 are both set to pins 1 and 2. Having PMAC-Pack Backplane
Jumpers E4 and E5 set wrong can damage the IC!

PMAC-Pack is shipped as standard with a ULN2803A sinking (open collector) output IC for the eight
outputs. These outputs can sink up to 100 mA, and utilize internal 3.3Kohm pull up resistors to go high. A
typical interface is shown in Figure 2- 6.

The user can provide a high side voltage (+12 to +24V) into +V (pin 2) of the JOPTO OUT connector,
and allow this to pull up the outputs by connecting pins 1 and 2 of the PMAC-Pack Backplane Jumper
E4. Backplane jumper E5 must also connect pins 1 and 2 for ULN2803A sinking output.
