GEO drive family

The Geo Drive family of 1 and 2-axis, 3-phase amplifiers supports a wide variety of power ranges, motors, and interfaces. Built in a small, book-style package, the Geo Drive comes in three variations: Geo Direct PWM, Geo MACRO Drive and Geo PMAC Drive.

Geo Direct PWM Drive – 1- or 2-Axis Direct PWM Amplifier. 

Geo Direct PWM, using digital direct PWM output, designed to increase performance with the simplest and shortest path from the controller to the motor

Amplifier Features

• Direct Line Connections models for either 240VAC or 480VAC, 1-or 3-phase
• Ratings from 1.5A continuous to 60A peak
• DC bus operation from 24VDC to 740VDC
• Designed for UL and CE Certification
• One or two axis configurations
• Integrated bus power supply including shunt regulator and soft start
• Seven amplifier status display

Geo MACRO Drive – 1- or 2-Axis Direct PWM Amplifier with MACRO interface.

Geo MACRO Drive, designed to quickly and easily connect to the amplifiers over great distances using the MACRO fiber optic link.

Amplifier Features:

• Direct Line Connections: models for either 240VAC or 480VAC, 1-or 3- phases
• Ratings from 1.5A continuous to 60A peak

Geo PMAC Drive – 1- or 2-Axis Intelligent Amplifier.

The Geo PMAC Drive offers the best of both worlds with an intelligent amplifier that reduces cost, simplifies setup and increases performance with the full capability of the PMAC.

Amplifier Features:

• Direct Line Connections: models for either 240VAC or 480VAC, 1-or 3- phases
• Ratings from 1.5A continuous to 60A peak

• Designed for UL and CE Certification
• One or two axis configurations
• Integrated bus power supply including shunt regulator and soft start
• 7 segment amplifer status display
