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.
STATE
Enable the Regenerate
Fu nct ion
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,
t h e DC Mo d e o r the frequency is set between 40Hz and 80Hz. If the
state is OFF, the MX operates like a normal MX without the SNK o p t i o n
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 volt age 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 to keep the
current below the set current limit value. Th i s ove r -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.
d FREQ 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 De l a y 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 MX waits to apply the
programmed frequency shift to the EUT after the set current limit
level has been exceeded.
Output Relay Open delay
time. Output Relay Open
delay time. (De la y R)
Th is d e l a y determines how long the MX waits to open the output relay
after the frequency shift has been This delay determines how long the
MX waits to open the output relay after the frequency shift has been
applied and the current still exceeds the set current limit level. If the
frequency shift is set to 0.0Hz, this setting determines the time the
