A-1-5 Homing Mode Specifications
 Homing Method 33 and 34: Homing with Home Signal
In these homing methods, only the Home signal is used.
The operation start direction of the homing operation is the negative direction when the homing
method is 33, and the positive direction when the homing method is 34.
A homing error occurs in the following cases. (Home error = 1)
• If the drive prohibition inputs in both directions are ON at the same time.
• If the home signal is not detected before the drive prohibition input in the drive direction turns ON.
Precautions for Correct Use
During the homing operation, the stop function for Drive Prohibition - Stop Selection is dis-
abled.
 Homing Method 37: Present Home Preset
In this Homing method, the value of Home offset is considered as the present position.
You can use this method even when you are using an absolute encoder, but the position is not
saved in Home offset (607C hex). When the control power is turned OFF or when Unit Restart is
executed, the home set by this Homing method is disabled.
You can execute this Homing method only when the Modes of operation is set to Homing mode (hm)
and in the Servo ON state.
