HPG™ 13150 400 V RF Power Generator
Prerelease version
2. Power ramping recipe
The function mode allows you to determine the shape of a power ramp
within a certain time frame. There are four programmable time frames.
For each time frame, you may control the following parameters:
• Set the time duration of the presence of RF power from 0.1 second
to 1440 minutes
• Set the start value of the RF power in watts
• Set the end value of the RF power in watts
Creating Recipes Through the Host Port:
If you are using RS-232 , PROFIBUS , or Ethernet to control and monitor the
HPG generator:
Note: For host port commands, see Table 4-13 on page 4-41 .
1. Set the number of recipes:
Send one data byte for command 19 , representing the desired number of
recipe steps.
2. Specify the ramp time for each given recipe using command 21 :
a. Send one byte to select the step number 1 to 2
b. Send two bytes to set the ramp time value.
3. Specify the set point for each given recipe step using command 22 :
a. Send one byte to select the recipe step number 1 to 2
b. Send two bytes to specify the set point value.
4. Set the run time for each given recipe using command 23 :
a. Send one byte to select the recipe step number 1 to 2.
b. Send two bytes to set the run time in seconds.
5. Set the ramping rise time:
Send two bytes, least significant byte first, for command 31 , representing
the ramping rise time in tenths of a second.
6. Set the ramping fall time:
a. Send two bytes, least significant byte first, for command 32 ,
representing the ramping fall time in tenths of a second.
