EN-FM Series
1Nm to 15Nm Digital Servo Drive
Overview
The En-Series drives are stand-alone, fully digital brushless
servo drives designed and built to reliably provide high performance
and flexibility without sacrificing ease of use.
Whether the drives are utilized in base drive only applications or
with a closed loop controller, setup can be achieved in just minutes
with no-charge PowerTools software. The use of a State-Space
algorithm makes 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.
EN Base Drive Operation
The base EN drive can be easily controlled with single and multi-axis
controllers, PLCs and host controllers for medium power applications.
The analog torque or velocity modes can be used with classic position
controllers using analog outputs and encoder inputs. The pulse mode
is ideal for use with low-cost PLC stepper controllers.
FM Control Modules
FM control modules provide EN drives with "snap-on"
functionality for Indexing (FM-2), Programming (FM-3) and Advanced
Programming (FM-4). This modular approach allows users to choose the
level of advanced machine control they need, based on application
parameters.
- 90 to 264 VAC 1Ø input power 68 lb-in cont. torque, 3Ø up
to 132 lb-in cont. torque
- FM modules for position control and advanced communications
- Easy to install, set up and operation
- Compact, space saving design
- Pluggable connectors, Standard D-Shell and Screw Terminals
- State-Space Observer Control, which allows 10-1 inertia
mismatch out of the box and 50-1 with tuning
- Free PowerTools software and upgrades
- Programmable, optically-isolated I/O
- Internal registration capability with provision for external
shunt
- RS-232/485 serial communication interface using Modbus
protocol
- 14 segment status and diagnostic and display, time stamping
of last 10 faults for easy troubleshooting
- Field programmable flash memory firmware (upgrades are free)
- Custom motor support for any servo motor with encoder
feedback

FM-2 Indexing Module
The FM-2 module enhances EN drives by adding positioning capability
including Jog, Home and index functions. This module also includes
additional I/O with 8 digital inputs and 4 digital outputs.
FM-3 Programming Module
The FM-3 module transforms the EN into a fully programmable single
axis motion controller with 8 additional digital inputs and 4
additional digital outputs.
FM-4 Advanced Programming Module
The FM-4 Advanced Programming module has all of the features of the
FM-3 with added ability to create complex motion profiles for
sophisticated applications. This module also includes high speed data
capture, summation of multiple motion profiles, program multi-tasking
plus a range of other parameters.
Easy Set-up
With Powertools™ interface software, no previous programming
experience is required.
Power Tools FM Software
The Epsilon is very easy to commission and program using
PowerTools FM software. This Windows™-based programming environment
makes extensive use of drag and drop editing, tabbed setup screens
and hierarchical views.
PowerTools FM is used to select the operating mode and
motor, configure I/O, set velocity limits and torque levels, and
monitor drive and I/O Status.
