Use the INC/DEC keys, or the numeric keys followed by ENT to change MACHINE
POSITION and/or MACHINE OFFSET.
Description Because the PL-1746 is a programmable device, it can be set to display a position of
“zero” at any point in the machine cycle. Usually, the machine is jogged to the begin-
ning of a cycle, and MACHINE POSITION is set to zero at this point. This function
eliminates the need to adjust the physical coupling between the machine and resolver
in order to change the displayed machine position. The MACHINE OFFSET can also
be set directly by entering it's value.
Set MACHINE POSITION or MACHINE OFFSET before doing any PULSE or GROUP
OFFSET programming.
Note: When direction of motion reverses, one circular unit out of 4096 will be skipped.
This prevents position transducer jitter.
