Description of Each Unit
"
Servo Control Circuit board (JASP-WRCA01)
This is a circuit board which controls the servo motors of six axes of the manipulator. This
board controls the converter, amplifiers and the power ON unit (JZRCR-XSU02). The power
source is supplied by a servo control power supply.
"
Servo Control Power Supply (JUSP-RCP01AA
#
)
This unit generates DC power (+5V, +7V, ±15V) for servo control. AC input (Single
phase:200/220VAC) is supplied by power supply unit.
"
Converter
This exchanges the power source (3-phase : 200/220VAC) supplied by the power supply unit
for DC power source and supplies the power to amplifiers for each axis.
"
Amplifier
This exchanges the DC power source supplied by a converter for a 3-phase motor power
source and outputs to each servo motor.
"
Speed Monitor Board (JANCD-XFC01)
This monitors the robot motion speed and outputs a speed error signal to the servo control
board (JASP-WRCA01) if the speed exceeds the set value.
