Figure 4.58 The Interior of Electrical Module

The following power flow chart shows the opening/closing of the 3-phase AC power for motor power supply, generation of brake power, AC control power such as fan operation, and the distribution of SMPS power for DC device power supply. Each power supply is equipped with a circuit breaker or fuse to protect components from over current. The electrical board (BD5C0) is used to minimize the use of the cables used for the distribution of power.
