Heidenhain: Measuring and Test Equipment (PWM 20)
Analysis for HEIDENHAIN Encoders
HEIDENHAIN encoders provide all information necessary for commissioning, monitoring and diagnostics. PWM inspection devices and PWT testing devices are available specifically for analyzing the encoders. Testing devices are used for checking the function of encoders. The PWTs have fewer functions than the PWMs, much higher measuring tolerances and cannot be calibrated. There are two types of diagnostics, depending on how the devices are integrated:
Encoder diagnostics: The encoder is connected directly to the test or inspection device. This makes a comprehensive analysis of encoder functions possible.
Diagnostics in the control loop: The PWM phase meter is looped into the closed control loop (e.g. through a suitable testing adapter). This makes a real-time diagnosis of the machine or system possible during operation. The functions depend on the interface.
PWM 20 ATS Software
HEIDENHAIN offers an adjusting and testing package for diagnostics and adjustment of encoders with absolute and incremental interfaces. It consists of the following components:
PWM 20: Phase angle measuring unit for connection to a PC through the USB interface.
ATS: Adjusting and Testing Software with integrated local encoder database for automatic encoder identification.
The functions supported by the ATS software vary depending on the encoder and the encoder interface. The EnDat interface makes it possible not only to display the position value, but also to read out the online diagnostics, to read or write parameters, shift datums, set write protection and use further inspection functions, etc.
These statements in this document refer to the ATS software version V3.0
We recommend returning the PWM 20 to the HEIDENHAIN calibration service in Traunreut every two years in order to ensure traceable, accurate and error-free operation as test equipment.
