Available functions The functionality of the PWM 9 is divided into the PWT MODE and the PWM MODE.
The most important functions of the PWM MODE:
The most important functions of the PWT MODE:
Bar-graphic display of
Check-Ref function
29 – 462
Display of phase angle and on-off ratio
Display of scanning frequency
Measurement of signal amplitude, current consumption and supply voltage of measuring
system
Display of the internal UNIVERSAL COUNTER and the rotary encoder signal periods (pulse
count)
Display for reference signal, interference signal and count direction
Output of amplified scanning signals (interface board: 11 µApp, 1 Vpp) or of original scanning
signals (interface board TTL, HTL) via 3 BNC sockets, e.g. on an oscilloscope.
Signal amplitude
Signal quality
Width of reference signal
Position of reference signal
Adjustment help for mounting the scanning head on exposed encoders
Testing of encoders with distance-coded ref. marks
Note
Each PWM 9 is delivered together with detailed operating instructions.
These operating instructions can be found in the Internet in German and other languages
and can be downloaded at www.heidenhain.de/Services/...
A detailed explanation of the PWM 9 is part of our Training course on measuring systems
or a special PWM 9 training course.
We recommend to participate in a HEIDENHAIN service training course so that you can use
the PWM 9 effectively.
