Command Syntax
[SOURce:]VOLTage:DC#:LIMit:MAXimum
Description
Sets upper user limit for DC voltage programming for phase #. If # is
omitted, sets all available phases to value specified. User limits must
fall within actual hardware limits of the power source. Also, MIN limit
must be less than MAX limit.
Parameters
-425.0 – 425.0
Parameter Format
<nr2>
Example
VOLT:LIM:DC1:MAX 270.0

Query Format
[SOURce:]VOLTage:DC#:LIMit:RANGe?
Description
This query returns both upper and lower user limits for DC voltage
programming.
Returned Data Format

Query Example
VOLT:DC1:LIM:RANG?
-425.0000,425.0000
Query Format
[SOURce:]VOLTage:DC#:LIMit:SATuration:RANGe?
Description
Returns maximum DC voltage at which saturation of the output
inverter will occur. Saturation limits are determined in the maximum
peak voltage capability of the AC+DC components at the output of
the power source. For the AFX Series®, these limits are -425 and
+425V. The VOLT:DC1:SAT? returns the max. DC level that may be
programmed based on the programmed AC wave shape and RMS
level.
Maximum allowable values are:
Maximum positive peak voltage:
V_DC = V_peak_max - V_AC_peak_max
Minimum negative peak voltage:
V_DC = V_peak_min + V_AC_peak_min
Examples
V_AC = 300Vrms sine wave
V_DC = 425 - 1.41 *
300
(
V_DC_sat = 0
)
V_AC = 120Vrms sine wave
V_DC = 425 - 1.41 *
120
(
V_DC_sat = 255
)
V_AC = 0Vrms
V_DC = 425 –
0
(
V_DC_sat = 425
)
