What is a teach pendant? A teach pendant is a handheld device used for manual robot manipulation, programming, parameter configuration, and monitoring.

Teach pendant introduction

The teach pendant (FlexPendant), also known as a teaching programming device (hereinafter referred to as a teach pendant), is the core component of a robot control system. It is a device used to register and store mechanical motion or process memory, which is executed by an electronic system or a computer system. Regarding the programming and control technology of industrial robots, there have been many developments and new applications in the past few years, and the teach pendant is one of the components.

The reason why the teach pendant is widely used in the field of industrial robots is inseparable from the following advantages:

1.It has a disable switch to ensure the safety of equipment operation.

2.Monitor the status information of the robot and all equipment in the work unit.

3.Complete the test more conveniently and quickly.

4.The teach pendant can make real-time adjustments to the robot program.

5.The teach pendant can reliably and actively prompt the operator to make the required input.

6.The teach pendant can integrate many components in the work unit.

7.Allow the user to add control logic.

Application scenario

Handheld teach pendant, VGA/COM/USB three-group data connection embedded motion controller. 8-inch HD touch screen Linux interface. Ordinary PC development platform realizes high-performance multi-axis coordinated motion control and high-speed positioning control. Users can easily program the controller and build an automated control system.
