PL.FB

Description

PL.FB returns the position feedback value.

Note that this value is not the pure feedback value read from the feedback device, but also includes the value of the FB1.OFFSET and an internal offset set automatically by the FW when a homing switch is actuated.

AKD BASIC Note

Note that this value is not the pure feedback value read from the feedback device, but also includes the value of the FB1.OFFSET and an internal offset set by the user. If a new value is written to MOVE.POSCOMMAND then PL.FB will be automatically changed such that PL.ERROR (the difference between them) is unchanged.
