4) These are the values under SMC measurement conditions when the vacuum pump working continuously and may vary depending on the atmospheric pressure (weather, altitude, etc.) and the measurement method. 5) Impact resistance: The characteristics are satisfied after being tested one time in each of the X, Y and Z directions with energization.
4. Functions ■ Automatic mode In automatic mode, the electric vacuum gripper operates in an energy-saving manner, automatically setting a threshold value based on the vacuum pressure at gripping, the maximum vacuum pressure of the product. Below is the description of the energy-saving operation. Upon the grip command, the pump engages and starts suctioning.

■Factory reset The gripper can be reset to the factory settings if the current settings are uncertain. How to reset 1. Press and hold the button for 10 seconds or longer until [RSET] is shown on the left of the sub screen of the pressure monitor, and then release the button.
5. Mounting 5.1. Mounting ■Mounting the gripper on the robot 1) Insert the parallel pin into the robot tool flange pin hole. 2) Aligning the parallel pin with the oval hole of the main plate, mount the main plate on the robot with 4 hexagon socket thin head bolts provided, with a tightening torque of 5.2±0.5 N·m.
5.2. Wiring ■Mounting the M8 connector cable Connect the electric vacuum gripper’s M8 connector pin (plug) and the tool flange’s tool I/O connector (plug) together with the M8 connector cable (socket – socket). Do not energize while securing the connector. Check that the connector is not loose.

Pump Settings Open “Pump Settings” from the “URCaps” menu in the “Installation” tab. 1. Default mode: Allows the user to change the default gripper operation mode on the program and commissioning windows. The gripper has three operation modes: “Automatic” (default), “Manual” and “Continuous”. “Automatic”: In automatic mode, the electric vacuum gripper operates in an energy-saving manner, automatically setting a threshold value based on the vacuum pressure at gripping.

5.3.4. Commissioning The “UR+” icon on the top right of the interface allows the user to commission the gripper. to see the gripper’s grip or release operation, status, and vacuum pressure. 1. Commissioning: Sets the gripper’s operation mode and threshold values of each parameter during commissioning.
7. How to change the number of cups 7.1. Change to 1 cup (with flange) 1. Removal of the cup (1) Remove the suction cup with adapter from Plate B using a spanner. (2) Loosen the bolt (M4x8) to remove Plate B from Plate A. Be careful not to lose the O-ring.
8. Maintenance Perform the maintenance and inspection shown below in order to use the electric vacuum gripper in a safe and appropriate manner for a long time. 8.1. Maintenance for electric vacuum gripper Caution 1) Inspection before and after maintenance When removing the product from the robot, ensure that the power supply is turned off and the vacuum pressure inside the product is released.

2) Mesh If the mesh is used in such a way that foreign matter is absorbed from the air or the workpiece, it may become clogged, which will cause a reduction in the ejector performance. Clean the mesh periodically as necessary by washing, air blow and so on.
9. Precautions 9.1. Electric vacuum gripper precautions ■Designing Warning If power or air supply is shutdown, vacuum pressure may decrease and this product may drop a workpiece during gripping. It is necessary to take measures such as drop prevention so that injury and damage to machinery or equipment can be prevented.

2) Depending upon the weight and shape of the workpieces, the diameter, quantity, and shape of cups suitable for use will vary. The selectable cups will differ based upon conditions other than the above, such as the condition of the workpiece surface (presence or absence of oil or water), the workpiece material, and its gas permeability.
