3.5.3.2.VOLTAGE AMPLITUDE (AMP=5)
NOTE: The external sense lines must be connected to TB2 on the rear panel of
the AC Power System. If they are not properly connected an OUTPUT
FAULT message will result when the amplitude is programmed. Refer to
Figure 2-6.
The output voltage Amplitude may be programmed independently or simultaneously for
each phase.
Select the Amplitude (AMP) screen by entering keystrokes:
5 ENT
The display now shows the AMP parameter screen:
AMP MON A = 5.0
B = 5.0 C = 5.0
NOTE: The B and C values are optional and they are only displayed with either a
two or three-phase configuration.
Program all outputs to 115.5 volts with the keystrokes:
115.5 PRG ENT
Program phase A to 130.0, phase B to 110.0 and phase C to 90.0 volts simultaneously.
130 A PRG 110 B PRG 90 C PRG ENT
Slowly increase the output amplitude of phase B only:
B PRG ↑ (Hold until desired value is obtained.)
The output frequency can be programmed between 17 and 45 Hz. For operation between
these frequencies, the output voltage Amplitude (AMP) is limited to values less than that
described by the following formula:
AMP = Voltage Range * (FRQ)/45
