those (values) to the maximum value.
However, this is not true for the
gas channel values. If a gas channel (value) is larger than the de
fi
ned
maximum, the auto controller will respond with:
“Target value greater than de
fi
ned max”.
If a gas channel maximum is set to 0 or off, then sending a (value) to that
gas channel will generate the following response:
“Gas Channel x disabled” where x is the gas channel number.
It is very important to understand the operating limits of the Ion
Source and Hollow Cathode to prevent damage. Review the ion
source and hollow cathode manuals to determine appropriate
operating conditions. Contact KRI for assistance in establishing
operating conditions if necessary.
6.4.4.10 R - Monitor Command for Reading the Actual Feedback Values
The R command is used to get the actual feedback values from the auto
controller. It uses the same parameters as those described above for the
P command, except that there is no program number required and the ?
character is not used.
R:<parameter> – Get the current running (value) of <parameter>
Values are reported in Amps, Volts or sccm, appropriate for
the selected parameter(s).
Example: R:GS2<cr><lf> – Get current value of Gas Channel
2 feedback.
Example: R:ALL<cr><lf>
Example response in ‘Verbose’ mode:
“Gas Channel 1 = 18.300
Gas Channel 2 = 0.000
Gas Channel 3 = 0.000
Gas Channel 4 = 10.000
Discharge Volts = 200
Discharge Amps = 3.000
Keeper Volts = 31.400
