Epsilon Eb and EN Drives

The Epsilon Eb and EN 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 Eb and EN base drives can be quickly configured to many applications in less
than 5 minutes with PowerTools FM software on a PC running Windows® 95, 98, NT 4.0
and 2000.
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.
The EN drives are designed to accept a line of function modules that further enhance its use
in various applications.
• FM-1 Speed Module offers the user eight digital Torque presets, two additional
Summation modes, and an Alternate Operating mode.
• FM-2 Indexing Module enables the user to initiate up to 16 different indexes, jogging, and
a single home routine.
• FM-3 and FM-3DN Programming Modules offer complex motion profiling. A complex
motion profile consists of two or more indexes that are executed in sequence such that the
final velocity of each index except the last is non-zero. Logical instructions between index
statements can provide a powerful tool for altering motion profiles 'on the fly'.
• FM-4 and FM-4DN Programming Modules offer complex motion profiling, along with
multi-tasking user programs. A complex motion profile consists of two or more indexes
that are executed in sequence such that the final velocity of each index except the last is
non-zero. Logical instructions between index statements can provide a powerful tool for
altering motion profiles 'on the fly'.
The FM Function modules define complex motion by a configuration file that includes setups
and function assignments. For the FM-3 and FM-4 modules, the configuration file also
includes programs. The configuration file is created using PowerTools FM or PowerTools
Pro. The FM-1 and FM-2 modules use PowerTools FM software, and the FM-3, FM-3DN,
FM-4, and FM-4DN modules use PowerTools Pro software. Setup views have the same look
and feel as dialog boxes. The wiring of input and output functions is done through
