Absolute position linear encoder
When using an absolute position linear encoder, the data set type homing can also be carried out.
• For proximity dog type homing
For a proximity dog type homing, the nearest reference home position after proximity dog off is the home position. The linear
encoder home position can be set in any position. LZ (Encoder Z-phase pulse) is outputted based on the set value of [Pr.
PL01.2 Homing stop interval setting].
*1 This can be changed with [Pr. PL01].
• For data set type homing
For a data set type homing, when CR (Clear) is turned on, the position control counter is cleared and the current position is
stored as the home position data into the non-volatile memory (backup memory).
*1 This can be changed with [Pr. PL01].
