Moving a Robot or Motion Device With the MCP

Emergency Stop Switch

The emergency stop switch will stop program execution and turn off High Power. If your robot is equipped with brakes, they will be activated.

COMP/PWR Button

If High Power is enabled, the COMP/PWR button selects computer mode. If the system is in AUTO mode and High Power is disabled, the COMP/PWR button enables High Power and selects computer mode. In computer mode, an executing program or the system terminal has control of the robot. (If the robot has not been calibrated and High Power is turned on, the MCP emergency stop switch LED will be lit, and both the COMP/PWR and MAN/HALT LEDs will be off.)

After you press the COMP/PWR button to enable High Power, the High Power lamp begins blinking and the LCD prompts you to press the High Power button. You must press this button before within the allowed time (this time is programmable) or High Power will not be enabled.

If the system is in Manual mode and you press the COMP/PWR button to enable High Power, you need to take the following actions:

•release the MCP enable switch

•press and hold the MCP enable switch (position 2 in MCP-4)

•press the High Power button within the allowed time.

MAN/HALT Button

When there is no program executing, or a program has paused for a pendant teach routine, pressing the MAN/HALT button selects manual mode. In manual mode, the MCP has control of the robot. If a program is executing, the MAN/HALT button will stop program execution (without shutting off High Power).

Manual mode cannot be entered if High Power is off (E-Stop button LED not illuminated). To enable High Power, press the COMP/PWR button. The MCP is in manual mode when:

1.The LED on the MAN/HALT button is illuminated, and

2.One of the manual state LEDs is also illuminated (the manual state LEDs indicate the type of manual motion that has been selected, either World, Tool, Joint, or Free).

The system will remain in Manual mode until High Power is turned off or the COMP/PWR button is pressed. When you have finished moving the robot manually, press the COMP/PWR button to return control to the controller. If a program attempts to execute with the MCP in manual mode, the error “Comp mode disabled” will be generated.

When the MAN/HALT button is pressed the first time, the MCP will be in world state. Pressing the MAN/HALT button again selects the next state to the right (tool, joint, free), eventually wrapping back to the leftmost state (world). If manual mode is terminated and reentered (without turning off system power) the last active state is selected.

RS-422/485, XSYS, XUSR, RS-232/TERM specifications

Nortech Systems offers a comprehensive suite of serial communication solutions, including RS-232/TERM, XUSR, XSYS, and RS-422/485 interfaces. These products are designed to facilitate reliable and high-speed data transmission in various industrial applications, making them essential for connecting devices in automation, telecommunications, and data acquisition systems.

The RS-232/TERM interface is a widely adopted standard for serial communication, known for its simplicity and robustness. It supports point-to-point communication over relatively short distances, typically up to 50 feet. Key features include a maximum baud rate of up to 115.2 kbps, error-checking capabilities, and a straightforward connection process, making it ideal for connecting peripheral devices like printers, modems, and barcode scanners.

Building on the RS-232 standard, the XUSR and XSYS devices offer enhanced functionalities and flexibility. XUSR, for instance, supports not just traditional RS-232 connections, but also protocol conversion for various serial interfaces, facilitating seamless integration of legacy systems with modern networking technologies. It is particularly useful in environments where multiple protocols need to be managed simultaneously.

XSYS is designed for more complex applications and supports advanced communication features such as multi-drop configurations, enabling it to connect multiple devices on a single bus. This makes it suitable for extensive industrial networks where space and wiring complexity need to be minimized. Synchronous and asynchronous data transfer modes ensure that the XSYS is adaptable for both real-time data collection and standard command-response applications.

On the other hand, RS-422/485 interfaces excel in long-distance communication, allowing for data transmission over distances up to 4,000 feet. They are designed for multi-point connections, supporting up to 32 devices on a single bus through differential signaling, which enhances noise immunity. These characteristics make RS-422/485 particularly well-suited for environments with electromagnetic interference, such as factories or subways.

Nortech Systems’ serial communication solutions emphasize reliability, ease of use, and versatility. With their commitment to high performance and user satisfaction, these interfaces provide critical connectivity in today’s increasingly automated and interconnected world. Whether in data centers, manufacturing setups, or remote sensor networks, Nortech's offerings stand out for their reliability, efficiency, and adaptability, ensuring effective data communication across diverse applications.
