13. USING A LINEAR SERVO MOTOR
13 - 28
(2) Absolute position linear encoder
The home position reference position on the absolute position linear encoder is a position per 1048576
pulses (changeable with the third digit of the parameter No.PS01), which is based on the linear encoder
home position (absolute position data 0).
For the proximity dog type home position return, the nearest home position reference position after turning
the proximity dog signal off will be the home position. There is no restriction on the setting position for the
home position of linear encoder. The encoder Z-phase pulse (LZ) cannot be used.
