Festo P.BE−SPC200−EN en 0901d
M11 Offset for analogue nominal value specification
ć permitted in operating modes: Start/Stop
Nn M11 X<Offset> [Y.., Z.., U..]
<Offset> n Offset in [mm] or [°] n = ±9999.98
@n Offset saved in position register @n 1) n = 0 ... 99
Effect Equalizes the voltage/position assignment (see Fig. 7/18).
Example Example see under M10
Remark Ĉ The preset reference point for the analogue nominal value specification is the
project zero point.
Ĉ By specifying the offset you can shift the reference point.
Ĉ The possible positioning range is limited by the set software end positions.
Ĉ The command M11 must be issued before M10.
Ĉ The offset has no effect with the digital nominal value specification (input 5).
