Example – Homing
In this example, the drive performs a homing using Homing method 23.
When homing is started, the home switch is not active, so the machine is moved in
the positive (right) direction. The direction is changed by the rising edge of the
positive limit switch.
The load is moved in the negative direction until the falling edge of the home switch
signal is received.
