see whether there is liquid split on the switch. If yes,
clean the liquid and re-install the board.
6.5 Motor drive board
6.5.1 Introduction
The motor drive board consists of power drive module which is controlled by ARM to drive motors
valves and pumps.
6.5.2 Components
The structure of the main control board is illustrated in figure 6-5. It mainly is controlled by power
control, and monitors vacuum pressure. Power control consists of motors valves and pumps control.
The control function of the motor drive board is realized with an "ARM+FPGA" structure. The m board
mainly provides the following functions:
Valves and pumps control
Motors control
Vacuum pressure monitoring
