In operations involving industrial robots, what is true regarding pendant control?

1. It operates independently of the main control

2. It can only function in manual mode

3. It operates in parallel mode with the master control panel

4. It can only be used in emergencies

The correct answer is: It operates in parallel mode with the master control panel

Pendant control refers to a handheld device used to control industrial robots, often allowing operators to manipulate the robot directly during setup, maintenance, or in non-standard operations. When considering the interaction between the pendant control and the main control system, one key aspect is that pendant control typically operates in parallel mode with the master control panel. This means that both the pendant and the main control can function simultaneously, enabling operators to switch between different modes of control as needed without losing functionality. This capability allows for greater flexibility and safety during operations, as operators can use the pendant for fine-tuning movements or making adjustments while the main control maintains the overall oversight of the robot’s activity. Furthermore, the dual operation enhances the ergonomics of working with complex robotic systems, giving operators direct and immediate control when necessary. In contrast, the other responses highlight limitations or specific uses of the pendant control that do not account for its typical functionality. For instance, suggesting it operates independently from the main control overlooks the collaborative nature of the control systems. Additionally, implying that pendant control can only function in manual mode disregards its capability for integration into automated systems. Lastly, stating that it can only be used in emergencies fails to recognize the broader applications of pendant control in routine operations, maintenance, and
