„ Supplemental Explanation
1. If the fixed parameter for motion command code selection has been set to enable the use
of motion command codes and the motion command enable setting (OBC0008) has
been set to 1 (enabled), the number of reference units will be set. The number of pulses
will be set at all other times.
53 Position Monitor 2
(APOS2) ILC034
-2 31 to 2 31 -1
This parameter is valid when the fixed parameter for motion
command code selection has been set to enable using motion
command codes. The value does not include the value of
OLC006: Machine Coordinate Setting Zero Point Offset.
When using this parameter, add the zero point offset con-
verted to the current unit (reference unit or pulse).
The setting of OBC02D3: Position Monitor 2 Unit Selection
affects the data stored for this parameter.
1. OBC02D3 = 0
Indicates the current monitored position in reference
units. This parameter cannot be used if the fixed parame-
ter for unlimited axis length selection is set for an unlim-
ited length and OLC002: Machine Coordinate Setting
Zero Point Offset is not set to 0.
2. OBC02D3 = 1
Indicates ILC008: Position Monitor converted to pulses.

-2 31 to 2 31 -1
These parameters are used for ABS system infinite length
position control.
Encoder position at shutdown and pulse unit position at shut-
down are paired data that together are called ABS system
infinite length position control information.
ABS system infinite length position control information
must be saved periodically to M registers using a low-speed
drawing (DWG.L).
