The following sub-menus are available in the CONFIGURATION menu:
Entry Description
REGENERATIVE CONTROL
UNDER VOLT Sets the EUT shut-off voltage, Active only if the dFREQ listed
below is set to zero. This is the voltage (AC or DC) at which the
EUT will shut off. If set to a value that will allow the EUT to
continue operating, the SEQUOIA may be unable to limit the
current being fed back by the EUT.
OVER VOLT Sets the EUT over voltage limit. This is the maximum allowable
voltage (AC or DC) at which the EUT can operate. The output
voltage may be increased up to this level if the current limit is
exceeded to keep the current below the set current limit value.
This over-voltage
threshold also triggers the power source to
either change the programming frequency or reduce the output
voltage depending on the delta frequency setting (0.0Hz to
reduce the output voltage and any delta frequency to change the
programming frequency) after the DELAY F delay is reached.
dFREQ This setting determines the size of the frequency shift that will be
applied to the EUT after the current limit has been exceeded. If
set to 0.0 Hz, no frequency shift will be applied, irreverent in DC
mode.
DELAY This delay setting field is used to set the delay time for both the
Frequency shift event (Delay F) and the Output relay open event
(Delay R).
