4.5.1 PROGRAM EDITING (cont)
FREQ : Any desired output frequency from 20.00 to 5000 Hz. may be entered.
RANGE RESOLUTION
20.00 - 99.99 Hz 0.01 Hz
100.0 - 999.9 Hz 0.1 Hz
1000 – 5000 Hz 1 Hz
Va, Vb, Vc : Line to neutral voltages are entered for 1 Φ and 3 Φ Forms. Line to Line voltages are
entered for 2 Φ operation.
This defines the amplitude of the Power Source output,
Direct Coupled:
0 to 150 volts rms (Line-Neutral) in steps of 0.1 volts
Actual maximum output voltage varies depending on the power source
model, load, and input voltage.
Transformer Coupled: 0 to 375 volts rms (TRANSFORMER RATIO= 0.1-2.5)
steps of 0.1 volts for ratios < 1.0
steps of 0.5 volts for ratios > 1.0
WFa, WFb, WFc : Select the desired output waveform. Waveform 1 is always a sine wave. Waveforms
2-16 may be copied and/or edited as desired using the SETUP ( fn ) functions.
The UPC will attempt to generate the selected waveform at the rms voltage programmed.
Because of the difference in the rms voltage content of various waveforms the UPC may not be
able to reproduce the waveform at the voltage desired. If the waveform is peak-voltage-limiting,
then selecting transformer coupled output with a higher ratio may solve this problem.
Ilim : Programmable current limit can be set as desired. The range will change depending upon which
Power Source the UPC is controlling. One value is used for all three phases. This function is
average responding, RMS programmed.
PHb, PHc : Phase angle can be set from 0-359º for Phase B and Phase C, referenced to Phase A.
Phase A is always at 0º.
Pressing
STORE at any time during editing will cause the program to be stored. The V/I METER display
will become active.
Pressing
EXECUTE at any time during editing will cause the program to be stored and executed. The
V/I METER display will become active.
Pressing
EDIT again while in the Program Edit Mode will allow transients to be created and edited. The
TRANSIENT edit display will become active (see 4.5.2).
