Inverter Positioning
Section 5-3
ORIGIN SEARCH:
ORG(889) ORG(889) performs an origin search or origin return operation.
• Origin Search:
Pulses are output to establish the origin based on origin proximity input
and origin input signals.
• Origin Return:
The positioning system is returned to the origin.
The parameters for pulse output 0 or pulse output 1 must be set in advance in
the PLC Setup to perform either an origin search or origin return operation.
MODE CONTROL: INI(880) INI(880) changes the present value of inverter positioning or stops position-
ing.
F First word of
starting fre-
quency F (lower 4 dig-
its) Starting Frequency in Hz
Pulse output 0 or 1: 0000 0000 to 0001 86A0
hex (0 to 100 kHz)
J models: 0000 0000 to 0000 4E20 hex (0 to 20
kHz)
F+1 (upper 4
digits)

Operand Description
P Port specifier 0020 hex: Inverter positioning 0
0021 hex: Inverter positioning 1
C Control data 0002 hex: Changes the PV of the internal pulse
output.
0003 hex: Stops internal pulse output. Position-
ing will continue and the output value will not be
cleared.
0004 hex: Stops inverter positioning. Internal
pulse output will be stopped, positioning will be
stopped, and the output value will be cleared.
The next operation will not be accepted until the
error counter is cleared.
