7.4.8 Home Return Instruction (F177)
- When the trigger (execution condition) turns on, the home return is performed according to a specified
data table.
- On the completion of the home return, the elapsed value area is reset to "0".
- When the deceleration stop is requested by the F0 instruction during the pulse output, the deceleration
stop is performed.
- Even when the home input is on, the pulse output starts by the execution of this instruction.
- When the near home input turns on during acceleration, the deceleration operation starts.
- There are two kinds of control method, which are type 0 and type 1.
Operation modes of Home return operation
There are two kinds of operation modes, which are type 0 and type 1.
Type 0
The home input is effective regardless of whether or not there is a near home input, whether
deceleration is taking place, or whether deceleration has been completed. Also, the home return can be
performed without the near home input.
Type 1
In this mode, the home input is effective only after deceleration (started by near home input) has been
completed. If the leading edge of home input (off to on) is detected during the operation at a creep speed
after the deceleration operation, the pulse output stops.
