The DMC-300xx is higher speed than Galil’s prior generation single-axis controllers; The 125 microsecond servo loop update time is twice as fast and the 15MHz encoder frequency and 3 MHz stepper pulse output are 25% faster.

The DMC-30012 model is packaged with an 800W amplifier for driving brushless servo motors at 20-80 VDC, up to 10A continuous, 15A peak. The fully digital, transconductance amplifier is a sinusoidally commutated brushless motor amplifier that minimizes torque ripple compared to drives using trapezoidal commutation. This is especially important for applications using low friction linear motors. The amplifier provides commands for initialization of the brushless motor using either hall sensors or encoder feedback.

Other features of the DMC-300xx motion controller include PID compensation with velocity and acceleration feedforward, non-volatile memory for user programs, multitasking for simultaneously running up to four programs, and I/O processing for synchronizing motion with external events. Modes of motion include point-to-point positioning, position tracking, jogging, contouring, electronic gearing, ECAM, and PVT.

The DMC-300xx provides optically isolated inputs and outputs as a standard feature. It also provides two 100Base-T Ethernet ports that can be daisy-chained, allowing multiple units to be connected without the use of an Ethernet hub. I/O includes forward and reverse limit inputs, homing input, 8 uncommitted digital inputs, 4 uncommitted digital outputs, 2 uncommitted analog inputs and 1 uncommitted analog output. The DMC-300xx accepts position feedback from both a main and auxiliary encoder. Quadrature encoder feedback is standard with BiSS and SSI formats available as an option.

Motion Control Tips

Simotion D motion control systems are ideal for production machines covering all levels of performance; from simple single-axis positioning tasks to complex synchronous applications, with extremely short cycle times on a large number of axes. Thanks to its scalability, Simotion D offers users a high degree of flexibility for the ever-changing demands of machine automation. The Simotion D drive-based multi-axis control system not only offers PLC, motion control and advanced technology functions, but also an integrated drive control based upon Siemens Sinamics S120 drives.

With the new Simotion D445-2 DP/PN and D455-2 DP/PN versions, the performance range has been extended even higher. Compared to the previous generation, the maximum quantity has been doubled to 128 axes and the memory capacity significantly expanded. This has increased the PLC and motion control performance by a factor of three. With Simotion D445-2 DP/PN and D455-2 DP/PN, the previously optional Profinet I/O interface has now been integrated on the modules as standard. This frees up the option slot for other expansion cards. The onboard interface is equipped with an integrated three-port switch and facilitates different network topologies such as line, star or tree structures, without the need for additional external switches. The interface not only supports real-time (RT), but also isochronous real-time (IRT) data exchange and can be operated as a controller and/or device of another controller.

In addition to the Profinet interface, Simotion D445-2 DP/PN and D455-2 DP/PN also have two Profibus and two Ethernet interfaces, as well as 28 digital I/Os, of which 16 can be used for technology tasks such as output cams and measuring inputs with microsecond resolution.

Two versions of the new control are available in the same compact, power-dense package size of 51.7cc, slightly larger than a matchbox. The BGE 3508 model is designed for 10-30V input with 75W of continuous and 225W peak power, while the BGE 6005 model can produce 120W continuous and 300 W of peak power with 60V input.

These new controllers are suitable for use with brushless or conventional brushed DC motors similar to Dunkermotoren’s BG and GR/G ranges. Information about the motor’s rotor position can be supplied to the positioning controller either by the voltage or by an encoder in the case of commutator motors or, for brushless motors, by Hall sensors or an incremental encoder. The controls incorporate protection against over-voltage, low voltage and excessive temperature.

If 4-quadrant digital speed control is desired, the control can be commanded to run in either direction, stop and hold with torque, and stop without torque (coast) through digital inputs. Other inputs can switch between programmed speeds or allow for a variable analog speed reference. Accel/decal ramps for the motor can also be programmed. The control offers the capability for a motor to function as a stand-alone, programmed servo which interfaces to the rest of the machine via digital and analog IO.

The new BGE 3508/6005 controllers offer many different modes of operation to choose from, such as analog or digital torque control, analog or digital speed control and digitally selectable position control (relative, absolute, and modulo).

Designed for volume OEM applications, the Dunkermotoren BGE 3508/6005 controllers offer a design alternative for restricted space applications where the additional length of an integral control motor may not be feasible. They can also be encapsulated to provide additional protection in extreme environmental conditions.

CANopen is the most widespread application layer in non-automotive control applications and market researchers predict that by 2015 some 400 million CAN chips will be used annually in a wide range of applications such as medical equipment, heavy vehicles, door control systems and throughout commercial and industrial automation systems.
