Axes control circuit board
8.2.1
Major axes control circuit board
The major axes control circuit board controls the servomotors of the robot’s six axes. It also
controls the converter and the PWM amplifiers. Mounting an external axes control circuit
board of an option makes it possible to control the servomotor of nine axes, including the
robot axes.
The major axes control circuit board also has the following functions:
•
Brake power supply control circuit
•
Shock sensor (shock) input circuit
•
Direct-in circuit
