Mounting a Rotational Drive Unit

Overview

You can mount a gearbox/motor combination at the mounting points for the gripper. This unit could be used for rotating an attached gripper or drive mechanical components inside an end-effector system. The appropriate combination of motor and gearbox has to be determined according to the application specifications. The mounting flange is compatible with many commonly used gearboxes.

Mounting a Rotational Drive Unit

Step	Action
1	Fasten the gearbox (1) to the mounting points provided for this purpose on the parallel plate (2). Pitch circle diameter 79 mm (3.1 in): 8 x M4 (3), tightening torque: 2.2 Nm (19.5 lbf-in); property class of the screws 8.8 or greater or A4-80 or greater. NOTE: Observe the permissible weights and distances. For further information, refer to Mechanical and Electrical Data. The maximum tilting torque at the parallel plate is 175 Nm (1549 lbf-in). For further information, refer to Load Capacity Diagram.
2	Ground the gearbox/motor combination in accordance with local standards and regulations at a single, central point. NOTE: When grounding the robot, use cables that comply with the applicable local standards, for example, cables that conform to NEC 70 / NFPA 79 in the USA.

DANGER
	ELECTRIC SHOCK DUE TO IMPROPER GROUNDING Ground robot components in accordance with local, regional and/or national standards and regulations at a single, central point. Verify that the motors are connected to the central ground. Failure to follow these instructions will result in death or serious injury.

Multipoint grounding is permissible if connections are made to an equipotential ground plane dimensioned to help avoid cable shield damage in the event of power system short-circuit currents.
