Target Position Change Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

Target position change function

The "target position change function" is a function to change a target position to a newly designated target position at any
timing during the position control (1-axis linear control). A command speed can also be changed simultaneously.
The target position and command speed changed are set directly in the buffer memory, and the target position change is
executed by "[Cd.29] Target position change request flag".
