The Red Drive servomotor driver & controller from Rotalink (www.rotalink.com) has effectively lessened the cost barrier for brushed DC precision motion control, according to the company. Now, Rotalink is launching the new BLDC10A Brushless Red Drive – a brushless version of Red Drive that provides the same user-friendly flowchart based software and price-performance benefits of the brushed version. The product, which has a 10A input current rating from a 12VC–24VDC supply voltage, includes incremental encoder input, 27 programmable TTL level I/O pins for digital and analogue machine interfacing, and hall sensor inputs for brushless commutation.
Compared with its brushed servo counterpart, the product’s modular design concept has a separately supplied SA1 serial port adapter to easily program the controller with the Red Drive computer-based graphical software. For cost-effective and faster OEM product development, a microprocessor chip is separately available to allow the full board version and its integral servo drive to be utilized in the pre-production and design phases with the IC version included in the final machine for full production. The option also gives machine users the flexibility to select and design-in I/O requirements and the optimum power components for the application.
The BLDC10A Brushless Red Drive can be easily programmed with the use of a “drag & drop” flowchart programming method that eliminates the complexity associated with other motion controllers available in the market. The Windows program permits scaling of gearbox and encoder resolution into meaningful units during setup along with I/O interfacing assignment. The setup stage also includes entering no-load speeds for automatic tuning and catalogue values for motor stall-torque. Homing, limits and reset inputs can also be set.
