Axidyne Axiom Plus PV10 Tolomatic Brushless Servo Controller/Drive

The Tolomatic Axidyne Axiom Plus PV Series Brushless Servo Conrollers/Drives use a high speed Digital Signal Processor (DSP) to perform all calculations necessary for high bandwidth, digital control of three-phase brushless servo motors. All tuning parameters are set and stored digitally using the Axiom Plus setup software. In addition, the unit includes a 1-1/2 axis controller function with user assignable I/O and an integrated PLC.

With brushless motors, the Axiom Plus incorporates state-of-the-art Space Vector Commutation to give 12.5% better bus voltage utilization than traditional sinusoidal commutation drives. This allows for improved motor speed/torque performance over older technology trapezoidal or sinusoidal motor drives.

In addition, the Axiom Plus implements a Flux Vector, or field oriented, current control algorithm. This allows for precise, high bandwidth current control in each individual motor phase and minimizes torque variations due to slight phase-to-phase differences within a motor's windings. It also minimizes nontorque producing motor current for less motor heating and better speed/ torque performance than with traditional trapezoidal and sinusoidal control algorithms.

Three power levels of Axiom Plus are manufactured: • Axiom Plus PV10 with a continuous current rating of 5A and a peak rating of 10A from a single or three phase power source. • Axiom Plus PV20 with a continuous current rating of 10A and a peak rating of 20A from a single or three phase power source. • Axiom Plus PV30 with a continuous current rating of 15A and a peak rating of 30A from a single or three phase power source.
