The DMC-21x2 and DMC-21x3 controllers are identical except the DMC-21x2 has 100 pin high-density connectors for breaking out the signals and the DMC-21x3 has 96 pin DIN connectors for breaking out the signals. All references to the DMC-21x2 in this manual also apply to the DMC-21x3. The DMC-21x2/21x3 is the Galil economy stand-alone multi-axis controller. The controller series offers many enhanced features, when compare to previous series, including high-speed communications, non-volatile program memory, faster encoder speeds, and options for bolt-on amplifiers or breakout boards. Each DMC-21x2/21x3 provides two communication channels: RS-232 (up to 19.2K Baud) and 10BaseT Ethernet. A 4Meg Flash EEPROM provides non-volatile memory for storing application programs, parameters, arrays and firmware. New firmware revisions are easily upgraded in the field.
Designed to solve complex motion problems
the DMC-21x2/21x3 can be used for applications involving jogging, point-to-point positioning, vector positioning, electronic gearing, multiple move sequences, and contouring. The controller eliminates jerk by programmable acceleration and deceleration with profile smoothing. For smooth following of complex contours, the DMC-21x2/21x3 provides continuous vector feed of an infinite number of linear and arc segments. The controller also features electronic gearing with multiple master axes as well as gantry mode operation. For synchronization with outside events, the DMC-21x2/21x3 provides uncommitted I/O, including 8 digital inputs (16 inputs for DMC-2152 thru DMC-2182) and 8 digital outputs (16 outputs for DMC2152 thru DMC-2182). The DMC-21x2/21x3 also has an additional 40 I/O and 8 analog inputs when the DB-28040 is added to the controller. Further I/O is available if the auxiliary encoders are not being used (2 inputs / each axis). Dedicated TTL inputs are provided for forward and reverse limits, abort, home, and definable input interrupts.
Overview of Motor Types
The DMC-21x2/21x3 can provide the following types of motor control: 1. Standard servo motors with +/- 10 volt command signals 2. Brushless servo motors with sinusoidal commutation 3. Step motors with step and direction signals 4. Other actuators such as hydraulics - For more information, contact Galil. The user can configure the axes separately for any combination of motor types, providing maximum flexibility. Commands can be sent in either Binary or ASCII. Additional software is available for automatictuning, trajectory viewing on a PC screen, CAD translation, and program development using many environments such as Visual Basic, C, C++ etc. Drivers for DOS, Linux, Windows 3.1, 95, 98, 2000, ME, NT and XP are available.
