Epsilon EP 

10-240 VAC, Single Phase, 50/60Hz Input
2.2 - 16.0A RMS (4.4 - 32 Peak)
115V / 230V

The compact, easy-to-use Epsilon EP servo drive is scalable from a simple amplifier to a completely programmable 1.5-axis motion controller. For added application flexibility, the Epsilon EP is available in three models:  Epsilon EP-B (base), Epsilon EP-I (indexer), and Epsilon EP-P (programming).

Each model is available with five drive power stages:  2.2A, 4.0A, 6.5A, 9.0A and 16.0A. This provides the capability to deliver over 198lb-in (22.4Nm) of torque at the rated motor speed and 396lb-in (44.8Nm) of peak torque for high demanding, pulse-duty applications. The Epsilon EP offers four of the most popular network connections for industrial controls:  RS485 (with standard Modbus RTU interface) is on all models allowing interfacing to PC tools, simple HMI’s and drive-to-drive configurations. 

Optional ProfiBus DP and DeviceNet communication configurations are available for system integration to common PLC platforms. EtherNet (standard on every Epsilon EP-P) opens up a world of interfacing possibilities (see the communications section under the Options tab for more information).

• Epsilon EP- I  - Indexer drive - Position controller provides Home, Index, and Jog motion profiles

• Epsilon EP - Base drive -  Ideal for servo applications utilizing an external motion controller
  

 Performance Advantage

Control Techniques has incorporated several advanced features and capabilities in the Epsilon EP family to make these drives even more powerful and easier to use. The key features are incorporated into the four variants of this product line. The four variants are:

Epsilon EP-B – Base

The base drive is ideal for servo applications utilizing an external motion controller. It accepts an analog command signal and sends out position feedback. The EP-B has the unique capability of combining an analog command with a preset velocity for trimming or advance/retard operations. The EP-B drive is an excellent choice for stepper replacements or centralized control systems.

Epsilon EP-I or EP-IDN – Indexer

The EP-I drive is a highly capable position controller that provides Home, Index, and Jog motion profiles. The EP-I holds up to16 unique indexes that also can be chained together to create complex motion profiles. The EP-I has a unique alternate mode feature whereby it can perform an Index or Home function and then switch to an alternate mode such as Analog Torque, Analog Velocity, or Pulse Follower mode on the fly! This compact indexing drive is a cost effective solution for countless applications.

Epsilon EP-P, EP-PDN and EP-PPB – Programming

The EP-P drive provides the highest level of control by allowing the user to create complete programs to sequence the motion control along with other machine functionality. The EP-P can be used to solve the most complex motion applications and still be easy to use thanks to Control Techniques' FREE PowerTools Pro configuration software. PowerTools Pro uses simple drag-and-drop and fill-in-the-blank screens that make setup a snap. User programs are created using a text-based motion language that is as easy to read as it is to program. If you don’t know the command, simply drag it in from the drop-down box and PowerTools Pro will assist you with the syntax. With intuitive software and plenty of online help, programming this servo drive is truly “Motion Made Easy!”^®

Additional features include:

Real-Time Program

A Real-Time Program (RTP) is a user program that executes in a single servo update. A RTP allows synchronous execution of a user program with the internal motion kernel which enables the possibility of real-time modification of motion profiles, monitoring of key performance indicators, or to make time critical calculations needed to get the most out of your motion control system.

Electronic Camming

Programming electronic cams has taken a huge step forward with Control Techniques' easy-to-use camming functions. PowerTools Pro offers a unique graphical interface which show the motion engineer exactly what the cam profile looks like in polar or linear coordinates. Cam data can be imported from a CAD system or entered directly from the PowerTools Pro software or even self generated within a user program. Epsilon EP supports several different types of interpolation types including linear, cosine, square, cubic spline, and jerk free offering flexibility in trajectory generation. Cam profiles can be started as easily as turning on an input, with no user program involved. Of course for advanced capabilities, user programs can be also used enabling access to a wealth of cam information and dynamically monitoring.

Modbus Master

Modbus Master takes machine control capability to a whole new level. No longer limited to the drive's on-board I/O, the Modbus Master can manage a very large number of I/O and communicate updates to any Modbus follower device, giving machine builders extensive control options.

Position TrackerTM

Analog position control and Fieldbus position control allow the Epsilon EP to replace an expensive PLC motion control module with a simple, low cost analog signal or Fieldbus register. With Position Tracker, the closed loop feature of the position controller has been integrated into the drive itself. The user simply sends the drive an analog or Fieldbus signal that is proportional to the absolute motor/actuator position. Advanced features such as "teach" functions also contribute to faster set up.

Built-in Timers

These timers provide a simple and accurate way to trigger an action based on a previously initiated time delay. Select from up to seven different timer types to match your needs.

Ethernet Programming

The EP-P drive uses common Ethernet protocols for all levels of networking ranging from applications setup and monitoring to communicating to PLC’s via Ethernet/IP or connecting to an operator panel using Modbus TCP/IP.

Dual Loop Mode (EP-P)

For those applications where it is required to command motion based on feedback from a linear encoder, for example, PowerTools Pro has the functionality to configure the EP-P drive for Dual Loop mode. Whether the feedback is linear or rotary, a user can define motion in terms of the secondary feedback and let the Epsilon calculate the relative motion required by the motor.

Communications                                                                                                              

EtherNet, Profibus, DeviceNet

Optional ProfiBus DP and DeviceNet communication configurations for system integration to common PLC platforms, and Ethernet, standard on every Epsilon EP-P, opening up a whole new world of interfacing possibilities are also available. The Epsilon EP-P’s EtherNet port supports EtherNet/IP, Modbus TCP/IP, HTTP, and SMSC with up to eight simultaneous connections (sockets) at a single time. That means you can be online with your HMI at the same time as your PC Tools, monitoring drive status remotely via a web browser, and have the drives communicating to each other for a true distributed control system, all at the same time!

The Ethernet port is configured to communicate using two industrial protocols: EtherNet/IP and Modbus TCP/IP. Communication setup is easily done with drag and drop drive information into the Ethernet Mapping. The EP-PDN, EP-IDN (DeviceNet) and EP-PPB (Profibus) are the Epsilon EP drives with these industry standard fieldbus options.

The EP-P has built in RS485 multi drop serial ports. The ports use industrial standard Modbus RTU. Making connectivity easily with many PLC and HMI products.

Position Tracker™ – Fieldbus Indexing replaces expensive PLC motion controllers with fieldbus communications. Motion profiles can be dynamically changed on the fly.
