Function and Operation

This instruction uses a relative drive method to perform a 1-speed positioning instruction. For this instruction,
the transfer distance from the current position to the target position should be specified together with a plus or
minus sign. This method is also referred to as the incremental (relative) drive method.
→ For details on the maximum speed, bias speed, acceleration time, and deceleration time, refer to

When a high-speed output special adapter is used as a destination for pulse output on a FX
the output shown in the following table for rotation direction signals.
When a built-in transistor output is used as a destination for pulse output on a FX
use transistor output for signals rotation direction.
