4.1. Overview
The Robotiq Hand-E Gripper is controlled directly via Modbus RTU using a RS485 signal. It can also be controlled via an optional
Robotiq Universal Controller using an industrial protocol (refer to the
instruction manual of the Robotiq Universal controller
). The
programming of the Gripper can be done with the Teach Pendant of the robot or by offline programming. The communication method
used to control the Hand-E Gripper does not change the control logic or register setups described in the following subsections.
Tip
Robotiq suggests using the Robotiq User Interface test software to explore the various features of the Gripper, like object
detection and force control.
Since the Robotiq Hand-E Gripper has its own embedded controller, high-level commands, such as "Go to requested position" are
used to control it.
Info
The operator can:
- Control force, speed and position of the Gripper fingers.
- Finger movement is always synchronized, movement is initiated via a single "Go to requested position" command.
- Parallel or encompassing grip is performed automatically.
- A built-in object detection feature is available; the user can be notified after an object is picked once the "Go to" command
has been initiated.
- Engage directional (open or close) auto-release for emergencies.
Control using registers
The Gripper has an internal memory that is shared with the robot controller. One part of the memory is for the robot output; gripper
functionalities. The other part of the memory is for the robot input; gripper status. Two types of actions can then be performed by the
robot controller :
1. Write in the robot output registers to activate functionalities;
2. Read in the robot input registers to get the status of the Gripper.
The Gripper Register Mapping section will map the different registers used to control the Gripper or to read its status while theRobot
Output Registers & Functionalities section will detail the output (write) register functions, and the Robot Input Registers & Status section
will detail the input (read) register status. The figure below is a representation of the memory and the control logic of the Gripper.
