measured voltage and current; unchecked causes the indicators to show the commanded
values of voltage and current, respectively.
When Start Ramp is clicked, information from the check boxes and # of Cycles is passed to the
example program and used to start ramp execution (see PAR. 4.6.3).
The Error in and Error out boxes are standard error callouts, showing 0 for no error, and an error
code and associated string if there is an error.
4.6.3 SOFTWARE TIMED RAMP EXECUTION
Clicking the Start Ramp button on the Software Ramp panel (Figure 4-8) causes the Ramp
Function Panel (Figure 4-9) to be displayed as the ramp is being generated. Checking the
Readback Voltage or Readback Current checkboxes above the DC VOLTS or DC AMPERES
indicators cause the Voltage and Current indicators to show measured voltage and current
vs.commanded values of voltage and current if unchecked.
FIGURE 4-9. RAMP FUNCTION PANEL, CURRENT RAMP
The information from the Software Ramp Panel is passed to either KepcoDCPwr Software
Timed Ramp Example.vi for a voltage ramp or KepcoDCPwr Current Software Timed Ramp
Example.vi for a current ramp. The computer sends the proper commands to the KLP that gen-
erate the ramp. The checkboxes for Readback Voltage, Readback Current can be altered while
the ramp is being generated to allow the indicators to display either measured or commanded
voltage or current. The Disable @ End and Repeat checkboxes can also be altered while the
ramp is being generated.
