Note 2) Timing chart with no I/O input. The start will delay if vibration occurs.
Note 3) The start time varies from the different conditions.

No.
Items
Description
1
Parameter setting for
home position return
Set the parameter of home position return speed, home position return creep
speed, home position return acceleration/deceleration time.
2
Confirm the start of home
position return
Make sure MEND is in closed-circuit state, standby in the open-circuit state.
3
Specify Point No.
After PCSEL1. . . 4 is open-circuit, specify points NO. 0. No need when start the
home position return by HOME.
4
Start of home position
return
After 10ms when input PCSEL1. . 4, change the PCSTART1 or HOME from the
open-circuit to closed-circuit.
5
Confirmation of command
execution
Open-circuit from standby to MEND. If open-circuit, make the PCSTART or HOME
to the open-circuit.
6
Confirmation of action
completion
Confirm the action completion by MEND. When the MEND changes from
open-circuit to closed-circuit, the action completed.
7
Confirmation of home
position return completion
After action completion, confirm the home position return completion by HEND.
When the HEND is closed-circuit, the home position return completed.
8.9.7 Detailed description for home position return
A) Home position return with arbitrary position
Home position return with the current position or Encoder phase Z near the current position.
