Motion controller

Driving up to three DC motors

Roboteq offers the FDC3260 motion controller, which supports the CiA 402 profile. It is able to control up to three motors.

The motion controller is capable of driving three DC motors up to 60 V and 60 A per channel. The CANopen device targets mobile robots and automatic guided vehicles (AGVs). The three power outputs are particularly effective for XYZ stabilization platforms, flight simulators, or for driving three thrusters in underwater robot applications.

The product incorporates a Basic Language Interpreter capable of executing over 50 000 instructions per second. This feature can be used to write scripts for adding custom functions, or for developing automated systems without the need for an external PLC or micro-computer.

The motors may be operated in open- or closed-loop speed or position modes with a 1-kHz update rate. The motion controller includes inputs for three quadrature encoders for speed and traveled distance measurement. It features current sensing that will automatically limit the power output to 60 A in all load conditions. The device also includes protection against overheat, stall, and short-circuits.

The controller includes up to 8 analog, 10 digital and 4 pulse inputs. Four 1-A digital outputs are provided for activating lights, valves, brakes, or other accessories. The controller’s operation can be optimized using nearly 80 configurable parameters, such as programmable acceleration or deceleration, amps limits, operating voltage range, use of I/O, and more.

A free PC utility is available for configuring, tuning, monitoring and exercising the motor. The motion controller comes in a 106 mm x 106 mm x 30 mm case with an aluminum bottom plate for cooling.

The FDC3260 is available now to customers worldwide at $595 in single quantities. Product information and software can be downloaded from the company’s website.
