HEIDENHAIN PWM 8 Operating Instructions Manual page 12

If e.g. the soft key BNC A is pressed, the assignment of the BNC socket A can be changed:
Switching the BNC memory:
The assignment of the BNC sockets is stored in three BNC memories that can be called
successively.
Each time the soft key
The display of the active BNC memory is highlighted:
Changing the signals in the BNC memories 1 to 3:
The signal in the active BNC memory is automatically stored each time it is changed by
pressing the soft keys
After power interruption the signals of the BNC memory active last are allocated to the BNC
sockets.
Notes on the use of the BNC sockets:
•
When using the BNC sockets to measure the encoder signals with an oscilloscope,
be sure that the workstation and the operator are properly grounded!
• A floating oscilloscope should be used to display the encoder signals with as little interference
as possible. Always connect the oscilloscope to the socket of the switch cabinet of the machine
tool to avoid signal distortions caused by different ground potentials.
The following encoder signals can be connected with the BNC sockets:
Interface Board
11µApp
1Vpp
TTL, HTL
*) Signal is generated in the PWM 8.
