Precautions for Correct Use Precautions for Correct Use
When you perform absolute positioning, set the target position so that the settings of the Modulo
Maximum Position Setting Value and Modulo Minimum Position Setting Value axis parameters
are not exceeded. If the target position is set outside of the settings of the Modulo Maximum
Position Setting Value and Modulo Minimum Position Setting Value axis parameters, a Target
Position Setting Out of Range error (error code 5478 hex) will occur.
In-position Check
An in-position check is performed for this instruction according to the settings in In-position Range
and In-position Check Time axis parameters.
Re-execution of Motion Control Instructions
You can change the operation of the instruction if you change an input variable during positioning and
change Execute to TRUE again. Input variables Position (Target Position), Velocity (Target Velocity),
Acceleration (Acceleration Rate), and Deceleration (Deceleration Rate) can be changed by re-execut-
ing the motion control instruction. For details on re-execution of motion control instructions, refer to the
NJ/NX-series CPU Unit Motion Control User's Manual (Cat. No. W507) or NY-series Industrial Panel PC
/ Industrial Box PC Motion Control User's Manual (Cat. No. W559).
Multi-execution of Motion Control Instructions
For details on multi-execution of motion control instructions, refer to the NJ/NX-series CPU Unit Motion
Control User's Manual (Cat. No. W507) or NY-series Industrial Panel PC / Industrial Box PC Motion
Control User's Manual (Cat. No. W559).
Execution during Execution of Other Instructions
You can switch to this instruction or buffer this instruction if you execute it during execution of
another instruction. You can buffer one instruction per axis. Specify the operation of this instruction
with BufferMode (Buffer Mode Selection) for multi-execution of instructions.

Aborts the instruction being executed and switches to this instruction.
If the direction of axis motion is reversed by switching instructions, the motion will be
reversed according to the Operation Selection at Reversing axis parameter.
Buffers this instruction and executes it automatically after the current instruction is
completed.
Starts the buffered instruction at the velocity (transit velocity) at which the current
instruction reaches the target position. The operation of the current instruction is
changed so that the axes reach the target position at the transit velocity. There are
four methods to specify the transit velocity. These are described below.
The lower of the target velocities of the current instruction and the buffered instruc-
tion is used as the transit velocity.
The target velocity of the current instruction is used as the transit velocity.
The target velocity of the buffered instruction is used as the transit velocity.
The higher of the target velocities of the current instruction and the buffered instruc-
tion is used as the transit velocity.
