EPR, EPC<br>Programmable Cam Controllers

Cam controllers execute the control function on the basis of the machine position or in a time-controlled manner. The function can be compared with the cam of a disc, whereby the switch-on and switch-off points for every outputs are determined according to the sections of the circle.

They are used wherever a quick and accurate control operation is essential depending on a fixed connection to the machine position, for example on packaging machines or glue application devices. The position is identified by a rotary encoder connected to the device.

Programming is done either via the keyboard and display integrated at the front or with the help of a connected PC.

A significant advantage of the devices EPR, EPC is the possibility of optimising switching points in operating machines and compensating delay times of connected actuators, depending upon the speed (downtime compensation).

Other important advantages of all variants are the significantly high speeds as compared to the PLC, the exact switching points, multiple programmes in one device, simple programme designing and modification as well as accurate downtime compensation to precisely 1 ms.

Programming is done either via the keyboard and display integrated at the front or with the help of a connected PC.
