Bit 5: Position Reference Type
Set the value of the OL1C setting parameter (Position Reference Setting) to either 0
(Incremental value addition method) or 1 (Absolute value specification method).
0: Incremental value addition method (default).
This method adds the amount to move to the current position reference value and then issues
the reference.
1: Absolute value specification method.
This method is used to set an absolute position.
Bit 6: Electronic Cam Phase Compensation Type
Set the reference method for the OL28 setting parameter (Phase Compensation Setting).
This parameter is valid only when the system is used as an electronic cam (i.e., when bit 1 in
OW05 is 1).
0: Incremental value addition method (default).
1: Absolute value specification method.
Electronic Cam Precautions (When Bit 1 in OW05 Is 1)
• If this parameter is set to 1 (Absolute value specification method), implement measures to
prevent drastic changes in the reference position before you use phase control. If not, the
axis may move abruptly, which is extremely dangerous.
Set the OL28 setting parameter (Phase Compensation Setting) to the same value as
Example
that of the IL14 monitor parameter (32-bit DPOS).
• This parameter can be changed at any time, but do not change this setting during phase
control. The axis may move abruptly, which is extremely dangerous.
Electronic Shaft Precautions (When Bit 1 in OW05 Is 0)
• The increment that is set in the OL28 setting parameter (Phase Compensation Setting)
(i.e., the difference between the previous high-speed scan and the current high-speed scan)
is added to the target position regardless of the setting of this bit.
Bit 8: SERVOPACK Parameter Access Selection
Set whether the common parameters or the vendor-specific parameters for each vendor are
used for the commands.
0: Vendor-specific parameters (default).
1: Common parameters.
Motion Subcommands
Motion Subcommands
Set the motion subcommand that is used with a motion command.
