Processing details
This instruction executes one-speed positioning by incremental drive. Specify the positioning address in the incremental
system, in which the transfer direction and transfer distance from the current position (relative address) are specified for
positioning.
• For (s1), specify the relative positioning address in user units. (The address must be within the range of -2147483647 to
+2147483647 number of pulses.)
• For (s2), specify the command speed in user units. (The speed must be 200 Kpps or lower in frequency.)
• For (d1), specify the axis number from which pulses are output.
• For (d2), specify the bit device of the normal complete flag or abnormal end flag for the DRVI instruction.
For details on the function and error code, refer to
Built-in positioning manual.
Precautions
Two devices are occupied from the device specified in (d2). Make sure that these devices are not used in other controls.
For other precautions, refer to
Built-in positioning manual.
