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 relay is open and the
frequency is set between 40Hz and 80 Hz. If the
state ids off the MX operates like the normal MX
without the SNK option installed. In normal mode
only 20% of normal operating current can sunk
and the MX will generate errors 31 and 32.
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.
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 F* Frequency Shift
application delay
time. 0.25 to 5.00 sec 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.
DELAY R* Output Relay
Open delay
time. 0.25 to 5.00 sec 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
output relay will be opened after the UNDER
VOLTAGE is applied
PREVIOUS
SCREEN Returns to previous screen.
NOTE: DELAY F and DELAY R are linked together as DELAY when entered from the front
panel.
Parameters set in the REGENERATE CONTROL screens are retained in non-volatile memory
between uses. They are NOT part of the setup registers however. Thus, only one set of
parameters is retained reflecting the last used settings with the exception of the STATE which is
always OFF at power up.
The same SNK parameters can also be programmed over any of the available remote control
interfaces using SCPI commands. Refer to the MX Programming Manual for details on
programming syntax.
