Please refer to chapter 5 for more information about the input pins and the output pins in the
motion control function block T_DMCServoHoming.
There are several modes of returning home. These modes are described below.
 The value in SR1078 (SR1178, SR1278...) is 1.
The motor used rotates clockwise. After it comes into contact with the negative limit switch
specified, it will rotate counterclockwise until a transition in a Z-phase signal from low to high
occurs.
 The value in SR1078 (SR1178, SR1278...) is 2.
The motor used rotates counterclockwise. After it comes into contact with the positive limit
switch specified, it will rotate clockwise until a transition in a Z-phase signal from low to high
occurs.
 The value in SR1078 (SR1178, SR1278...) is 3 or 4.
1. The value in SR1078 (SR1178, SR1278...) is 3.
The motor used rotates counterclockwise. After a transition in DOG's signal from low to
high occurs, the motor will rotate clockwise until a transition in a Z-phase signal from
low to high occurs.
2. The value in SR1078 (SR1178, SR1278...) is 4.
The motor used rotates counterclockwise. After a transition in DOG's signal from low to
high occurs, the motor will rotate counterclockwise until a transition in a Z-phase signal
from low to high occurs.
If the motor used comes into contact with a limit switch when it returns home, it will stop
after an error code is generated.
 The value in SR1078 (SR1178, SR1278...) is 5 or 6.
1. The value in SR1078 (SR1178, SR1278...) is 5.
The motor used rotates clockwise. After a transition in DOG's signal from low to high
occurs, the motor will rotate clockwise until a transition in a Z-phase signal from low to
high occurs.
2. The value in SR1078 (SR1178, SR1278...) is 6.
The motor used rotates clockwise. After a transition in DOG's signal from low to high
occurs, the motor will rotate counterclockwise until a transition in a Z-phase signal from
low to high occurs.
