Epsilon EP – Compact 1.5 Axis Servo Drive
2.2 – 16.0 A rms (4.4 – 32 Peak)
115V / 230V
Epsilon EP, Control Techniques’ compact and easy-to-use servo drive, is scalable from a simple amplifier to a completely programmable 1.5-axis motion controller. The Epsilon EP is available in three flexible models – Epsilon EP-B (base), Epsilon EP-I (indexer), and Epsilon EP-P (programming). Each model is available with five drive different power stages—2.2A, 4.0A, 6.5A, 9.0A and 16.0A—providing the capability to deliver over 198 lb-in (22.4 Nm) of torque at the rated motor speed and 396 lb-in (44.8 Nm) of peak torque for those high demanding pulse duty application. Connectivity is the key. The Epsilon EP offers four of the most popular network connections for industrial controls. RS485 with the 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 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.
Our Epsilon EP servo drive product line offerings include integrated motion control solutions. The Epsilon EP product line offers product scalability with base, indexer and programming variants.
Variants and their respective solutions include:

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:
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.
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 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.
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.
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.
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.
