Drive Unit
There is one
Drive Board
for each axis (total of six)
plugged into the drive back plane. The Robot Computer
identifies each board on the back plane through the 64
pin ribbon cable. The drive boards primarily consist of
at least 3 sets of two power transistors on each board.
(Other circuitry on the drive boards are used to detect
faults in this system) Two sets of transistors are controlled
by the robot computer and the third set is calculated
according to the first two. The transistors act like
switches, sending 340 VDC to the motor coils.
Depending on the position of the motor magnets the
corresponding transistors will be turned ON to cause
the motor to turn. There are at least 3 (three) wires
coming out of the back of a drive board going to the
motor (one wire for each phase). If there are more than
three wires they just doubled or tripled up the wires.
Trouble shooting
of the drive boards is performed
primarily by monitoring of the red LED on the front of the
board. The LED indicates a drive fault but not necessarily
the drive board. (When the control is turned on the drive
fault LED's are all on until the Robot Computer identifies
each board from left to right.) If you get a red fault LED
the first thing to do is re initialize the computer and try
again. If the red LED comes on again, check for a
mechanical bind by pressing the brake release push
button for the axis concerned, and see if the axis moves
freely. Then check the continuity of the motor and the
motor wiring. The resistance of the motor coil should be
approximately .5 to 2 ohms. The resistance to ground
should be greater than 10 Megohms. The best way to
check these resistances is by unplugging the drive
board in question and checking resistance from the
Back Plane through the motor. If the motor is OK then
the problem is probably the drive board.
Replacement
of a drive board requires no special
setups or adjustments.
