3.2.1 Errors and effects

Errors are detected and displayed when the board is carried in or carried out.

If an error occurs, immediately turn off the output of the drive system which is

the cause of the error. However, the backup in production will not be reset.

Error type Details

IN buffer error

① IN motor continuously turns for 10 seconds or more.

② IN sensor turns on for 0.5 second or more when WAIT sensor is on.

③ IN sensor and WAIT sensor turn on simultaneously when IN motor is rotating.

Centering station

error

① CENT motor continuously turns for 10 seconds or more.

② STOP sensor turns from off to on when C.OUT sensor is on.

OUT buffer error

① OUT motor continuously turns for 10 seconds or more.

② C.OUT sensor and OUT sensor turn on simultaneously.

Backup error

① UP sensor does not turn on for 2 seconds or more after backup is on.

② DN sensor does not turn off for 2 seconds or more after backup is on.

③ DN sensor does not turn on for 2 seconds or more after backup is off.

④ UP sensor does not turn off for 2 seconds or more after backup is off.
