b) Drive sequence
At the time of loading:
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.
Detect circuit
2.2) Drive system
Controlling an E/L motor by the control unit enables the following function.
