b) Drive sequence
At the time of loading:
A
1 One of LOADPHT, LOADSWR, LOADSWL starts driving with H. 2 All of LOADPHT, LOADSWR, LOADSWL detect
H at the same time. 3 Detecting H of INISW. 4 Detecting L of LOADSWR. 5 Detecting L of LOADSWL and stopping
E/L motor.

At the time of ejecting:
1 Starting driving H of LOADSWR. 2 Detecting L of INISW.
3 Detecting L of LOADSWL and after reverse brake (16ms), stopping E/L monitor.

2) Elevation system
2.1) Detect system
It uses a linear position sensor (VR1), converts stage chassis level to voltage value and captures it by a microcomputer
A/D to detect absolute position.
