Introduction

Epsilon Indexing Drives

The Epsilon EP-I drives are stand-alone, 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 Epsilon drives can be quickly configured to many applications in less than 5 minutes with Emerson Control Techniques PowerTools Pro v4.01 software on a PC running Windows® 98, NT 4.0, 2000, ME or XP.

Complete diagnostics are provided for quick troubleshooting. A status/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.

Figure 1: Epsilon EP-IDN Drive Feature Location

Epsilon EP drives are rated at 90 Vac to 264 Vac input voltage. Epsilon EP drives are available in three current ratings.

Drive Model	Continuous Current	Peak Current
EP202-Ixx-EN00	2.2 A RMS	4.4 A RMS
EP204-Ixx-EN00	4 A RMS	8 A RMS
EP206-Ixx-EN00	6.5 A RMS	13 A RMS

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

FM-2 Indexing Module

The FM-2 Module is a compact and rugged indexing module that attaches to the front of the base drive (MDS drive module). It enables the user to initiate up to 16 different indexes, jogging and a single home routine. It also provides eight digital input lines and four digital output lines in addition to the four input and three output lines available on the base drive. The FM-2
