DMC-1780 allows the user to select which channel will be used. The DMA channel chosen should be reflected within the Galil software registry. 2.5 illustrates these settings.

Please note earlier controller revisions (Rev. E and earlier for DMC-1740, Rev. C and earlier for DMC-1780) did not have hardware jumpers for DMA channel selection.

(Optional) IRQ (Interrupt) Jumpers

IRQ jumpers are not necessary for communication with the Galil controllers. Rather, they are an option that may be used for notifying the PC of events that occur on the motion controller. The selectable IRQ jumpers are only available on the DMC-1700. The PCI drivers for the DMC-1800 will automatically assign it an IRQ based on system availability.

On the DMC-1700, select which IRQ line will be used when the controller needs to notify the PC of an interrupt. You will need to select an IRQ line which is open on your PC, meaning not shared with any other device. Within the Galil Software Registry, the corresponding IRQ line should be entered into the controller registry information.

NOTE: For Version 7 Drivers and ISA/PC-104 controllers with new firmware, a jumper MUST be installed on one of the IRQ jumper pins in order to use Interrupt Communication (the default method of communication). Match the IRQ jumper on the board with an IRQ Setting that displays “No Conflicts” in the Device Manager.

If No IRQ lines are available or Interrupt Communication is not desired, the user must go to the “Controller Registration” menu and uncheck the “Interrupt Communication” method. Stall or Delay methods of communication will then be used. A Communication Timeout error will occur if this is not done.

(Optional) Motor Off Jumpers

The state of the motor upon power up may be selected with the placement of a hardware jumper on the controller. With a jumper installed at the MO location, the controller will be powered up in the ‘motor off’ state. The SH command will need to be issued in order for the motor to be enabled. With no jumper installed, the controller will immediately enable the motor upon power up. The MO command will need to be issued to turn the motor off.

The MO jumper is always located on the same block of jumpers as the stepper motor jumpers (SM). This feature is only available to newer revision controllers (Rev. F and later for DMC-1740, Rev. D and later for DMC-1780, Rev. C and later for DMC-1840). Please consult Galil for adding this functionality to older revision controllers.

DMC-1800, DMC-1700 specifications

The Galil DMC-1700 and DMC-1800 are advanced motion controllers widely recognized for their high performance and versatility in the automation and robotics industries. These controllers are designed to meet the demands of complex motion control applications, providing users with enhanced features and innovative technologies that optimize motion precision and efficiency.

One of the main features of the Galil DMC-1700 is its ability to handle up to 8 axes of motion control. This capability makes it suitable for a range of applications, from simple point-to-point movements to intricate trajectories in multi-axis systems. In contrast, the DMC-1800 extends this functionality, supporting up to 64 axes, making it ideal for large-scale automation environments.

Both models leverage Galil's powerful programming interface, which simplifies the development of motion control applications. The DMC-1700 and DMC-1800 controllers utilize a high-level programming language that supports advanced motion commands, including linear interpolation, circular interpolation, and complex motion profiles. This feature allows users to implement sophisticated motion sequences seamlessly.

In terms of connectivity, the Galil DMC series offers multiple communication options, including Ethernet, RS-232, and CAN bus, ensuring compatibility with various hardware and enabling easy integration into existing systems. The controllers also come equipped with digital and analog I/O ports, providing flexibility for sensor feedback and actuator control.

The advanced technology incorporated into both the DMC-1700 and DMC-1800 includes on-board PID control, which ensures precise motion control through closed-loop feedback. This results in improved stability and accuracy, particularly in high-speed applications. Additionally, the controllers offer extensive diagnostics and monitoring capabilities, allowing for real-time performance analysis and troubleshooting.

Another notable characteristic of these motion controllers is their compact design, which offers space-saving advantages while maintaining high processing power. Their robust construction and ability to operate in challenging environments make them suitable for a wide range of industrial applications, from CNC machining to assembly lines.

In conclusion, the Galil DMC-1700 and DMC-1800 motion controllers stand out due to their high-performance capabilities, advanced programming features, and flexibility in connectivity. With their ability to handle complex motion control tasks efficiently, these controllers are invaluable tools for engineers and manufacturers looking to enhance their automation processes. By integrating Galil's innovative motion control technology, industries can achieve greater precision, speed, and reliability in their operational workflows.
