The generator supplies 10 kV controlled. However, if the current of 2mA is reached,
then it is limited to this value, i.e. if necessary the voltage decreases. The numbers are
displayed here in hexadecimal.
RXPDO1 for 10 kV and 2 mA in U-mode
Example: 20kV, I-mode, 2mA:
In I-mode the roles of U target and I target are exchanged with each other. If the high-
voltage generator, for example, is switched on for 2 mA and 20 kV by RXPDO1 with I-
mode, the Utarget does not limit the output current, as long as the output voltage is
below 20 kV. (See Figure 5.3.3.) If the output voltage reaches 20 kV, the output current
does not continue to increase. (The high-voltage generator behaves than as in U
mode).

Output from messages and warnings
Under certain conditions the high-voltage generator switches off the output voltage.
This can be from user specified conditions, as for example Umin threshold during I-
mode, number of electrical arcs reached, etc. In addition permanent self tests and tem-
perature monitoring is done, that lead to warnings or to shut down.
In this case the generator sets the corresponding bit and always the collective mes-
sage "Collective malfunction" in the status word.
The high-voltage generator is then in an error state. The state of the high-voltage gen-
erator can be determined from the TXPDO1 via SYN-object. If the high voltage is
switched off, for example, due to exceeding Imax in U-mode, the TXPDO1 looks like
the following:
