Toshiba TS3100 - Restoring Home Position Data by HOME Function; Outline of HOME Function

MAINTENANCE MANUAL
4.4 Restoring Home Position Data by HOME Function
Batteries for backing up the position information of the position detector are housed in
the base unit of the robot. Unless the robot has been used for a long term, the
battery voltage drops and the home position data will be lost. Also, when the battery
voltage for backing up the internal memory of the X8GC printed board has dropped,
user’s set programs, parameters and absolute coordinates will be lost. To avoid this,
replace the batteries on a regular basis.
4.4.1 Outline of HOME Function
This function memorizes a specific coordinate value in each axis and restores the
original home position data by using the HOME function when the machine home
position data has been destroyed.
The set points are provided for HOME1 to HOME4, and the axis 1 to axis 3 plus (+)
side mechanical stopper positions are set in HOME3, and the axis 1 to axis 3 minus
(–) mechanical stopper positions in HOME4. The axis 4 is set at the 0° position
according to the home point match-mark.
For HOME1 and HOME2, you can specify any values. It is recommended that
when building up a system, you specify the place for securing the robot end.
