Introduction

Epsilon Eb Digital Servo Drive

The Epsilon drives are standalone, fully digital brushless servo drives designed and built to reliably provide high performance and flexibility without sacrificing ease of use.

The use of State-Space algorithms make tuning very simple and forgiving. The drives are designed to operate with up to a 10:1 inertia mismatch right out of the box. Higher (50:1 and more) inertial mismatches are possible with two simple parameter settings.

The drives can be quickly configured to many applications in less than 5 minutes with PowerTools software on a PC running Windows 95, 98, or NT 4.0.

Complete diagnostics are provided for quick troubleshooting. A diagnostic display on the front of the drive informs the user of the operational or fault status. The last 10 faults are stored in non-volatile memory along with a time stamp for easy recall.

Epsilon drives operate at 42 to 264 VAC standalone or at 24 to 375 VDC with an A.P.S. (Alternate Power Supply) and are available in two power ratings. The drive will fit in a 6 inch deep enclosure with cables connected.

Drive Model	Power Rating	Continuous Current	Peak Current
Epsilon Eb-202	650 W	1.8 amps	3.6 amps

Epsilon Eb-203	1100 W	3.0 amps	6.0 amps

Epsilon Eb-205	1750 W	5.0 amps	10.0 amps

The MG and NT motors that are matched to the Epsilon drives provide low inertia, high power to size ratios, and encoder feedback for accurate positioning.
