Axis Parameter Area
Section 4-4
Bit 08 to 11: Origin Detection Method
This setting specifies the origin detection method.
Bit 12 to 15: Origin Search Direction
This setting specifies the direction for detecting the origin input signal during
an origin search.
4-4-3
Operation Modes
The four operation modes are described below. The following abbreviations
are used in the wiring diagrams:
DCRI: Error counter reset input
DCRO: Error counter reset output
IC:
Input common
OACI:
Origin adjustment command input
OACO: Origin adjustment command output
OPI:
Origin proximity input
OS:
Origin input signal
PCSI:
Positioning completed signal input
PCSO: Positioning completed signal output
2
Single-direction mode
Detects origin while operating in designated origin search direction.
(Does not reverse.) Error stop at limit input for designated origin search
direction.
3
Reverse mode 3 (supported for unit version 2.3 or later)
Basic functions are the same as with reverse mode 2. When the direc-
tion is reversed at the origin proximity input signal, however, the origin
search operation will continue at the origin search proximity speed until
the origin input signal. (In reverse mode 2, when the direction is
reversed at the origin proximity input signal, operation continues by
accelerating toward the origin search high speed.) Use this mode to
reduce shock to mechanical systems.
Setting
Explanation
0
Takes origin input signal after origin proximity input signal turns ON (
↑
)
and OFF (
↓
).
1
Takes origin input signal after origin proximity input signal turns ON (
↑
).
2
Takes origin input signal without using origin proximity input signal.
3
Takes origin input signal after limit input signal turns ON (
↑
) and OFF
(
↓
), or OFF (
↓
), without using origin proximity input signal. (Enabled
only for single-direction mode.)
Setting
Explanation
12
Origin search direction
Use to specify the direction for detecting the origin input signal
during an origin search.
0: CW, 1: CCW
13
Origin search preset (supported for unit version 2.3 or later)
After the origin search has been executed and successfully com-
pleted, the present position can be set to any position.
0: Not set (default). Same function as previously.
1: Set. Set the position where the origin signal was detected to
any desired position. The desired position is set in advance in
the position parameter in the operating data area (for one axis,
words l + 8 and l + 9).
14 to 15
Not used.
