3.4 Resetting Axis To Home Position
Resetting the MHTH Headstock axis to Home position is typically done
during initial installation or after the servo motor is serviced.
To reset Home position, proceed as follows:
1. Place robot in TEACH MODE and slowly jog axis until homing pin hole
on
adaptor plate is accessible.
2. Install homing pin into homing pin hole in adaptor plate.
3. Jog the axis slowly until homing pin just touches stationary edge of
s
tructure. If you jog the axis too far, the pin will bend, causing an
inaccuracy. Slowly jog the axis in reverse until pin is straight, but still
touching the edge of structure.
4. Place the programming pendant in MANANGEMENT MODE.
5. Press the TOP {MENU} key on the programming pendant.
6. Cursor to {ROBOT} and press [SELECT].
7. Cursor to HOME POSITION and press [SELECT].
