Deceleration starts when the Proximity dog signal is turned ON. For the home position after turn OFF
of the Proximity dog signal, the position specified by the first Z-phase signal or the position of the first
Z-phase signal shifted by the home position shift amount (Pr.1285, Pr.1286) is used.

Deceleration starts when the proximity dog signal is turned ON. After the proximity dog, the motor
travels the specified travel distance (Pr.1287, Pr.1288). Then, it uses the position specified by the first
Z-phase signal or position of the Z-phase signal shifted by the home position shift amount (Pr.1285,
Pr.1286).
