9.11.3 REGENERATE Control Screen
Figure 9-46: REGENERATE CONTROL screen
The –SNK option mode of operation is controlled by parameters set in the REGENERATE
CONTROL SCREEN. Access to this screen is from the APPLICATIONS SETUP 2 screen by
selecting the SNK entry and pressing the ENTER key.
The following parameters are available to be programmed by the user.
Field Description Setting Range Purpose
STATE Enable the
Regenerate
Function ON / OFF This field allows the regenerative mode of operation
to be enabled. The regenerative state can only be
enabled if the output relay is open, the DC Mode or
the frequency is set between 40Hz and 80Hz. If the
state is OFF, the MX operates like a normal MX
without the SNK option installed. In normal mode,
only 20% of available current can be sunk and the MX
will generate an error 31 and 32. fault.
UNDER VOLT EUT under
voltage limit 0.0 to max V
range value 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 MX may be unable to limit the current being fed
back by the EUT.
OVER VOLT EUT over voltage
limit 0.0 to max V
range value 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 in an effort 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 Delta Frequency 0.0 to 6.0 Hz 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 Delay 0.25 to 5.00 sec 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).
