A-1-5 Homing Mode Specifications
This section describes the operation of the supported homing methods.
Homing Methods 8 and 12: Homing by Home Proximity Input and Home Sig-
nal
These Homing methods use the Home Proximity Input that is enabled only in some parts of the drive
range, and stop the motor when the home signal is detected.
The home signal is detected in the positive direction for Homing method 8 and in the negative direc-
tion for Homing method 12.
The operation start direction of the homing operation is as follows: When the Home Proximity Input
is OFF, it is the same as the direction in which the home signal is detected. When the Home Proxim-
ity Input is ON, it is opposite to the direction in which the home signal is detected.
The operation direction reverses by the positive drive prohibition input.
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 drive prohibition input in one direction is ON, and the drive prohibition input in the opposite
direction is turned ON although the rising edge of the Home Proximity Input is not detected.
• If the rising edge of the Home Proximity Input is detected in the home detection direction and then
the drive prohibition input turns ON before the home signal is detected
