Pulse Outputs
Section 5-3
ORIGIN SEARCH:
ORG(889)
ORG(889) performs an origin search or origin return operation. The required
PLC Setup parameters must be set before performing an origin search or ori-
gin return operation.
Origin Search
Positions the system to the origin based on the origin proximity input and ori-
gin input signals.
Origin Return
Returns the system from its present position to the pre-established origin.
MODE CONTROL: INI(880)
In addition to the various interrupt and high-speed counter functions, INI(880)
can be used to change the pulse output PV or stop the pulse output.
Note
This section explains the functions related to pulse outputs only. For details on
the INI(880) instruction’s high-speed counter or interrupt functions, refer to 5-1
Interrupt Functions or 5-2 High-speed Counters.
