EPOS P 24/5 - programmable positioning controller
The new programmable EPOS P positioning controller is a new addition to the successful EPOS family. With all the features of the online-commanded EPOS slave version, this new master version also has an integral processor and memory for stand-alone operation and independent controlling of up to 127 other units via CANopen bus. Programming complies with IEC 61131-3 standard. Standardized function blocks in accordance with PLCopen motion control standard make implementation easy.
EPOS P 24/5 is a freely programmable positioning controller with an integrated power stage for brushless and brush DC motors of up to 120 watts. This makes it ideal for very dynamic and minute precision drives and controlling systems. Several drives can be networked and coordinated through a standardized CANopen interface, particularly other EPOS slave units. Different operating modes can be pre-selected for controlling purposes (point-to-point, positioning controller with Feedforward, speed controller, torque control, Homing , electronic gearing, step/direction and position marker).

Force Control Industries, Inc. entered into the controls business in 1994 when it became apparent that many of the clutch/brake positioning problems associated with the Posidyne® clutch/brake were actually related to the controls, and not the fault of the clutch/brake. Many systems were built around a PLC, and scan time caused variable delays in the signal timing causing positioning errors. As the speeds increased, response became more and more critical, and millisecond variables caused unacceptable positioning errors.
The Posidyne® clutch/brake was often picked in critical positioning applications because of it's stopping consistency, however there were still position errors. The cold start to hot run change was most prevalent, as it is in all clutch/brakes. Many times the stop position flag would have to be adjusted after r unning for awhile, and if the machine was shut down for awhile, it may have to be readjusted again.
Positioning errors could also be caused by changes in temperature, speed, actuation pressure, or many other variables.
Force Control Industries, Inc. built the first control by buying components and installing into a box. This solved the scan time problem, but still left the adjustment needed due to other variables. A commitment was made by management to take a clean sheet of paper, and design and build a control that would not only solve the scan time problem, but would continuously self adjust to compensate for all of the other variables that affect clutch/brake drives.

For applications not needing the advanced features of a motion controller, the QD75 single-slot modules offer the flexibility to include or add motion to Q series control platforms. Features include linear and circular interpolation as well as multi-axis point-to-point commands. The QD75 modules are capable of 1,2, or 4 axis of control. The QD75-M type modules add the functionality and convenience of Mitsubishi’s high-performance Servo System Control Network (SSCNET). All of the QD75 modules are supported by easy to use Windows based programming packages.

Drivers and Controllers for piezo actuators
To fulfill various requirements in terms of driving and control conditions for its piezo actuators (static, pulse, dynamic), the CEDRAT Group has developed 3 different families of standard drivers:
CA45 rack: Low cost & compact (1 channel) linear voltage amplifier for precise and quasi-static motion.
LA75 rack: Linear voltage amplifier for dynamic and precise motion.
SP75 rack: Switching power amplifier for fast motion.
These standard drivers can be equipped with controllers and sensor conditioners.

The PS 90 is a modular designed position control for maximal nine axes, divided in three groups, each with three axes. Because of this special feature, it is possible to operate respectively three 2-phase step motors or DC servo motors (brush and brushless). Each axis has two inputs for incremental encoder or position measuring system. Thus, very precise positioning in closed loop mode is possible for all drive systems. Step motors can be operated from full step up to 256 micro steps per full step. The PS 90 can be operated by a handheld terminal or a PC via the integrated USB interface. Point-to-point positioning mode with different velocity profi les as well as complex continuous-path control like circular interpolation or 3-axes linear interpolation are possible. Because of safety requirements, an external emergency stop button is pluggable.
The software tool OWISoft is also part of the delivery. Thus, the PS 90 can be configured and operated comfortably.
Please order the required drive modules directly with the base unit.
