Analog Servo Amplifiers for Precision Motion Control

An analog servo amplifier receives analog control signals (typically -10V to +10V from a DAC) and converts them into the appropriate power output to drive the servo motor. The amplifier processes these signals through fault detection circuits and watchdog logic, then delivers controlled power (such as 120V 20A) to achieve precise motor positioning and speed control.

All servo amplifiers feature comprehensive safety systems including built-in E-stop functionality, automatic fault detection circuits, and watchdog logic. These safety features enable controlled braking, emergency power switching, and automatic fault monitoring to ensure reliable operation in demanding industrial environments.

Yes, the product line supports multiple motor configurations. The PWM servo amplifiers can control DC brush motors at 120V 20A, brushless motor amplifiers handle three-phase motors, and the Universal PWM controllers support both stepper and servo motors with configurable output modes, providing flexibility for various motion control applications.

These amplifiers are specifically designed for CNC retrofits with native LinuxCNC compatibility, support for proprietary encoder conversion (Fanuc and Panasonic), pre-drilled heat sink mounting solutions for easy installation, and comprehensive fault detection that integrates with existing E-stop systems, enabling seamless upgrades of older CNC machines to modern motion control.

The systems support single-ended, differential, and proprietary encoder types including Fanuc and Panasonic encoders. Signal conversion capabilities include serial to Hall conversion for Panasonic MUMS encoders and Fanuc signal conversion to standard Hall outputs, with encoder counting speeds up to 10 MHz and resolutions ranging from 32K to 1024K.

The controllers support expansion beyond the standard 4-axis capacity through daisy-chained board configurations. Multiple boards can be connected together to add additional axes, making the system scalable for applications requiring coordinated control of more than four motion axes.

The servo amplifiers deliver 120V 20A power output for both DC brush and brushless motor control. The PWM servo amplifiers feature 25ns PWM granularity for precise motor control, while the solid state relay systems operate across 5-60V DC for signal-level control and servo amp enabling functions.
