Detecting the mechanical origin

MINI system
When the command is given to detect the mechanical origin, the stage begins moving clockwise (i.e., in the - direction) at the operating speed (F) specified in the memory switches, stopping when the clockwise (-) limit sensor is detected. It then moves counter-clockwise (i.e., in the + direction) at the operating speed (F) for 1000 pulses. After stopping, it begins moving clockwise (i.e., in the -direction) once more at the starting speed (S), stopping when the clockwise (-) limit sensor is reached. It then moves counter-clockwise (i.e., in the + direction) at the operating speed (F) for 1000 pulses. This position is taken as the mechanical origin (SGSP series).

Information

With the SHOT-202, or SHOT-204MS, use MINI mode to detect the mechanical origin. The scale of the automatic rotation stage is adjusted to stop at around 0° when the mechanical origin is detected in MINI mode during half step. If the mechanical origin is not detected, the stage may be rotated clockwise or counterclockwise without limit.
Automatic rotation stages use a CW limit sensor as the origin sensor and return to the default origin.
