Heidenhain: Measuring and Test Equipment (PWM 9)

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.


The PWM 9 is a universal measuring device for checking and adjusting incremental linear and angular encoders.


Functions and B
enefits:

  • Connection to the oscilloscope via BNC connectors

  • Measurement of signal amplitudes, current consumption, operating voltage and scanning frequency
