30 – 564 HEIDENHAIN Service Manual iTNC 530 HSCI
30.3 PWM 9 encoder diagnostic kit
Brief description The PWM 9 set currently has the ID 512134-01.
The PWM 9 phase angle measuring unit is a universal testing device for inspecting and adjusting
HEIDENHAIN incremental encoders (linear , rotary and angle encoders).
There are different expansion modules available for checking the different encoder signals
(11 µApp, 1 Vpp, TTL, HTL).
The PWM 9 can be connected in series between the encoder and the control.
Inspections at "operating speed" are possible.
The signal amplitude is also measured when the encoder has stopped.
Three BNC sockets (A/B/C) are available for checking the encoder signals on an oscilloscope
(recommended by HEIDENHAIN).
For inspecting and adjusting HEIDENHAIN measuring systems in the workshop the PWM 9 can
also be used without subsequent electronics (e.g., control, position display).
If the PWM 9 is connected in the signal path between the encoder and the control:
Do not change the settings of the PWM 9 (e.g., parameters, encoder voltages) and do not switch
it off while the machine tool is operating.
Ignoring this may cause machine damage or personal injury!
Read the PWM 9 User's Manual, before you use the device.
