Executable Axis Status
You can execute this instruction for any axis for which Status.Synchronized (Synchronized Motion) in
the status of the axis specified for Axis is TRUE. An error will occur if the instruction is executed for an
axis in any other status.
Axis Limit
The axis limit functions for the command position to which the position offset is added.
The specifications of the axis limit depend on the specifications of the synchronized control instruction
currently in operation.
The related axis limit values are listed as follows.
•
Operation Settings Values
a) Maximum velocity
b) Maximum acceleration/Maximum deceleration
c) Velocity warning value
d) Acceleration warning value/Deceleration warning value
• Limit Settings Values
a) Following error over value
b) Following error warning value
c) Software limit values
• Command Position Overflow/Command Position Underflow
• In-position Check
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 OffsetPosition (Position Of
fset), Velocity (Target Velocity), Acceleration (Acceleration
Rate), and Deceleration (Deceleration Rate) can be changed by re-executing the motion control in-
struction.
For details on re-execution of motion control instructions, refer to the NY-series Industrial Panel PC /
Industrial Box PC Motion Control User’s Manual (Cat. No. W559).
Multi-execution of Motion Control Instructions
You cannot execute another motion control instruction during execution of this instruction.
A Motion Control Instruction Multi-execution Disabled error (error code: 543C hex) occurs if an attempt
is made to execute multiple instances.
Errors
If an error occurs during instruction execution, Error
will change to TRUE.
You can find out the cause of the error by referring to the value output by ErrorID (Error Code).
