Automatic Positioning To Home Position Function - Mitsubishi Electric MR-JE-*C Instruction Manual

12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE

12.4.17 Automatic positioning to home position function

When returning to the home position again with the home position fixed after power-on, this function enables
a high-speed automatic positioning to the home position.
If the automatic positioning to the home position is executed without completing the homing, [AL. 90.1 Home
position return incomplete warning] occurs.
After the power-on, perform the homing in advance.
(1) Device/parameter
Set input devices and parameters as follows:
Item
Homing mode selection
Home position return speed
Acceleration time constant/
deceleration time constant of
homing
(2) Timing chart
MD0 (Operation mode selection 1)
Servo motor speed
ST1 (Forward rotation start)
ST2 (Reverse rotation start)
POINT
The automatic positioning to the home position cannot be performed from
outside the setting range of position data. In this case, perform the homing again
using the homing.
