14.2 Axes Control Circuit Board
14.2.1 Major Axes Control Circuit Board (SRDA-EAXA21A)
The major axes control circuit board controls the servomotors of the
manipulator’s six axes. It also controls the converter and the PWM
amplifiers. Mounting the external axes control circuit board (SRDA-
EAXB21A) makes it possible to control the servomotor of nine axes,
including the robot axes.
The major axes control circuit board (SRDA-EAXA21A) also has the
following functions.
• brake power supply control circuit
• Shock sensor (shock) input circuit
• Direct-in circuit
