Motion Parameters
( 26 ) Zero Point Return
A typical example of a zero point return operation is shown below.
Refer to 7.2.3 Zero Point Return (ZRET) on page 7-15 for details.
OW 3C
Zero Point Return Method
Setting Range Setting Unit Default Value
0 to 19 − 0
Description
Set the operation method when the Zero Point Return (ZRET) motion command is executed.
With an incremental encoder, there are 17 different methods that can be performed for the Zero Point Return operation.
Refer to 7.2.3 Zero Point Return (ZRET) on page 7-15 for information on each method.
With an absolute encoder, the axis is returned to the zero point of the machine coordinate system regardless of which
method is being used.
OW 3D
Width of Starting Point Position Output
Setting Range Setting Unit Default Value
0 to 65535 Reference unit 100
Description Set the width in which the Zero Point Position bit (monitoring parameter IW 0C, bit4) will be ON.
OL 3E
Approach Speed
Setting Range Setting Unit Default Value
−2 31 to 2 31 −1
Depends on the
speed unit set in
Function Setting 1
(setting parameter
OW 03, bits 0 to
3)
1000
Description
Set the approach speed for a zero point return operation after the deceleration LS is passed.
The setting unit for this parameter depends on the Speed Unit Selection (OW 03, bits 0 to 3), but the
result of applying the speed unit setting is not shown here.
OL 40
Creep Rate
Setting Range Setting Unit Default Value
−2 31 to 2 31 −1
Depends on the
speed unit set in
Function Setting 1
(setting parameter
OW 03, bits 0 to
3)
500
Description
Set the creep speed for a zero point return operation after the ZERO signal is detected.
The setting unit for this parameter depends on the Speed Unit Selection (OW 03, bits 0 to 3), but the
result of applying the speed unit setting is not shown here.
OL 42
Zero Point Return Travel Distance
Setting Range Setting Unit Default Value
−2 31
to 2
31 −1 Reference unit 0
Description Set the distance from where the signal is detected to the zero point position.
