Controller enables smoother running for fast stepper motors


Controllers for stepper motors that are used in handling and automation tasks such as quality assurance or in photonics applications, test equipment or photonics alignment must be able to fulfill a large number of requirements. They should have smooth-running motors for high resolution and if possible, work in a closed servo loop, but at the same time, also be inexpensive and compact.

PI (Physik Instrumente) has introduced the new C-663.12 single-axis controller for 2-phase stepper motors. Thanks to the closed servo loop, the closed-loop stepper motor controller combines the advantages of both a stepper motor drive and a servo motor. This rules out any problems caused by step loss or overheating of the motor.

At the same time, the resolution of 2048 microsteps ensures low motor vibration and good position resolution. The high supply voltage of 48V and maximum 2.5A per phase means that plenty of energy is available for the motor; it can run very fast.

In addition, there are further features that are very convincing in practice: Up to 16 controllers can be networked with each other via USB or RS-232 and operated from the same computer. The easily understandable GCS programming language allows macros to be defined that the controller can then process independently.

It also includes an integrated data recorder, which allows you to read monitoring and diagnostics data at any time, and a USB interface for easy communication with a laptop or PC. Alternatively, an RS-232 interface simplifies integration into industrial applications.

Each controller is supplied with a wide-range-input power supply, RS-232 and USB cable, and extensive software so that it can be started up quickly and easily.
