Features - Emerson Epsilon Eb Series Reference Manual

Epsilon Eb and E Series EN Drives Reference Manual
The MG and NT motors that are matched to the Epsilon and E Series drives provide low
inertia, high power to size ratios, and encoder feedback for accurate positioning.

Features

• Digital drive design using DSP, ASIC and surface mount technologies.
• Epsilon and E Series E
Alternate Power Supply (APS) applied, the Epsilon Drive input range can be extended to
42 to 264 VAC.
• Small mounting footprint.
• Auxiliary logic power supply capability.
• Bus connections for external shunt capability. The E
shunts.
• Five optically isolated inputs and three optically isolated outputs.
• Built-in RS-232C to RS-485 converter for multi-drop applications.
• RS-232C/485 serial communications interface using industry standard Modbus®
protocol up to 19.2 kbaud.
• Diagnostic and operating mode status display.
• Extensive fault sensing and diagnostics, including storage and time stamping of the last
ten faults.
• Maximum input response time is 500 µs for command and input functions.
• Peak torque up to three times continuous motor torque rating.
• Sinusoidal commutation for efficiency and smooth motor motion.
• No potentiometers or selector switches.
• No tuning needed for no-load up to 10:1 inertia mismatch.
• High performance tuning based on inertia ratio, friction and response with PowerTools
software (available separately).
• High resolution encoder.
• Eight velocity presets.
• Programmable pulse follower ratio.
• Pulse mode input type selectable between differential and single-ended.
• Removable connectors for easy installation.
• Single cable connection to EMERSON Motion Control's AXIMA 2000 and 4000 multi-
axis controllers.
