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 and the frequency 
is set between 40Hz and 80Hz. If the state is OFF, the 
RS operates like a normal RS without the SNK option 
installed. In normal mode, only 20% of available 
current can be sunk and the RS 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 
RS 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. 
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). 
    Frequency Shift 
application delay 
time. (Delay F) 
This delay determines how long the RS waits to apply 
the programmed frequency shift to the EUT after the 
set current limit level has been exceeded. 
    Output Relay 
Open delay time. 
This delay determines how long the RS waits to open 
the output relay after the frequency shift has been
