10.6 Practical Use for a Home Return

10.6.1 When One Switch is Used as the Home Input

Example of usage method
- Connection
Only the home input switch is installed and connected. (No near home input switch is connected.)
- Input logic settings
The control code in the shared memory should be set as indicated below.
- Home input logic: Input exists when power is supplied.
- Near home input logic: Input exists when power is not supplied.
- Operation
When Home return is started, the motor rotates in the direction of home return
The motor rotates at the startup speed.
At this time, the near home input is already ON due to the Input logic setting.
The motor stops when the home input is made.
Example:
Note:
-Home return is executed at the startup speed.
-When the home input is connected to the Z phase output of the motor driver, one switch can not be
used as the home input.
-The above example is only applicable when the home return (in a Home search invalid mode) is
executed.
Reference (Key Points):
-Practical application of input logic. The near home input is set to "Input exists when power is not
supplied", and is not connected.
-There is no near home switch.
-There is only home input switch.
