On the linear scale with distance-coded reference marks (serial type), the
amount of movement on FL-speed during establishment of reference point is
set. If the reference point is not established despite the amount of FL-speed
movement exceeds this parameter, P/S alarm 5326 occurs. When this
parameter is set to '0', the setting of allowable move amount of FL feedrate on
establishment of reference point (linear scale with distance-coded reference
marks (serial)) is ineffective.
Caution
1. On reference point establishment of manual feed axis for simple
synchronous control, if you set this parameter on either master or slave
axis, it become effective on both master and slave axes automatically.
2. On angular axis control, this parameter setting of perpendicular axis is
ignored during the reference position establishment of the angular axis.
