Introduction
Epsilon EP-B Base Drive
The Epsilon EP-B 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 EP-B drive can be quickly configured to many applications in less than 5 minutes with Emerson Control
Techniques PowerTools Pro v4.0

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.

Epsilon EP drives are rated at 240 Vac input voltage and can operate with an input voltage from 20 to 264 Vac. The
Epsilon EP drives are available in three current ratings.
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.
