36042002 Tolomatic Control Board

The Tolomatic Axiom Brushed and Brushless Series Servo Motor Drives use a high speed Digital Signal Processor (DSP) to perform all calculations necessary for high bandwidth digital control of traditional brush and three-phase brushless servo motors in torque, velocity or position modes. All tuning parameters are set and stored digitally using the Axiom setup software.

With brushless motors, the drive incorporates state-of-the-art Space Vector Communication 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 drive implements a Flux Vector current control algorithm in the brushless motor versions. This allows for precise, high bandwidth current control in each individual motor phase. This minimizes torque variations due to slight phase-to-phase differences within a motor's windings. It also minimizes non-torque producing motor current for less motor heating and better speed/torque performance than with traditional trapezoidal and sinusoidal control algorithms.

The Axiom servo motor drives, when combined with Tolomatic brush and brushless servo motors, provide continuous torque up to 75 lb-in (10.7 Nm) and peak torque up to 150 lb-in (21.4 Nm) and speeds up to 6000 RPM.
