Compatibility and Service Notes
Brooks states that the manual drawings are generic and may not reflect a particular robot build; the robot Quality Report and purchase order control exact part-number matching. A 2017 Canon Anelva MAG-7 change notice confirms that Brooks later changed the theta-driver PCBA for component-obsolescence and motor-power-separation reasons, but it does not identify the old or new part numbers and therefore does not establish an interchange or replacement relationship for BR140718.
