3 Power Supply
3.1 Outline
The following figure shows an outline of the power supply system.
The machine is supplied with two channels of 24 V power (24 VP, 24 VL).
24 VP is mainly used by loads, and is cut off when the machine or its top cover is opened.
The circuit breaker (CB1) turns on in response to an overcurrent, thereby cutting off the
power to protect the circuit.
24 VL is first converted to 5 V by the regulator, and is used by logic elements and sensors.
The fuse resistor (R26) is designed to melt in response to an overcurrent in the circuit,
thereby cutting off the power to protect the circuit.
