Setup & Operation 2.6 Six-axis Drive Unit (Part Names and Functions)
The Drive Main Board receives position references from the Control Unit and
thereby drives the motors.
The Motor Driver module receives a reference from the DMB, and, outputs
three-phase current to supply power to the motor. (The photo shows a sample of
Drive Unit for a 6-axis Manipulator. From left to right: Axis 1 through 6.)
The supplied AC200V (or the local equivalent) power is regulated here and is output
as +24V.
A standard model comes with two cooling fans in the six-axis Drive Unit.
A protective filter is installed in front of the fan to filter out dust.
Check condition of the filter regularly and clean it as necessary. A dirty filter may
result in the malfunction of the robot system as the temperature rises in the Drive
Unit.
The Drive Power Board consists of two circuits: one rectifies AC200V (or the local
equivalent) and distributes the main power source to each motor driver that drives the
axes, and the other is an interface circuit of the LED on the front.
The supplied AC200V (or the local equivalent) power is regulated here and is output
as +5V.
The installed module is different depending on the Manipulator models.
