OW09
 Bit 0: Hold Command
The axis decelerates to a stop if this bit is set to 1 while an axis is in motion for a POSING (Posi-
tioning), EX_POSING (External Positioning), STEP (STEP Operation), or VELO (Issue Speed
Reference) motion command.
The axis remains held as long as this bit is 1. When the bit changes to 0, the hold on the axis is
released and the axis begins the operation again. When the hold is released, bit 1 (Command
Hold Completed) in the IW09 monitor parameter changes to 1.
0: Hold Command OFF (default).
1: Hold Command ON.
 Bit 1: Cancel Command
The axis decelerates to a stop and cancels all remaining movement if this bit is set to 1 while an
axis is in motion for a POSING (Positioning), EX_POSING (External Positioning), ZRET (Zero
Point Return), FEED (Jog), STEP (STEP Operation), VELO (Issue Speed Reference), or TRQ
(Issue Torque/Force Reference) motion command.
0: Cancel Command OFF (default).
1: Cancel Command ON.
 Bit 2: Travel Direction (JOG/STEP)
Specify the travel direction for the FEED (Jog), STEP (STEP Operation), and EX_FEED (Jog with
External Positioning) motion commands.
0: Forward (default).
1: Reverse.
 Bit 3: Zero Point Return Direction Selection
Specify the travel direction for the ZRET (Zero Point Return) motion command (valid for
DEC1+Phase-C Pulse, ZERO, DEC1+ZERO, and Phase-C Pulse).
0: Reverse (default).
1: Forward.
 Bit 4: Latch Zone Enable
Use this bit to enable or disable the area where the external signal is valid (the latch zone) for
the EX_POSING (External Positioning) motion command.
0: Disabled (default).
1: Enabled.
Setting Precautions
Always set this bit to 0 (Disabled) when a latch motion command other than the EX_POSING
command (i.e., LATCH or ZRET) is executed.
