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 except for 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.
Setting Range
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 M X operates like the normal M X without the
SNK option installed. In normal mode only 20% of normal
operating current can sunk and the M X will generate errors 31
and 32.
0.0 to max V range Sets the EUT shut off voltage, A ctive only if the dFREQ listed
value below is set to zero. This is the voltage (A C or DC) at which the
EUT will shut off. If set to a value that will allow the EUT to
continue operating, the M X may be unable to limit the current
being fed back by the EUT.
0.0 to max V range Sets the EUT over voltage limit. This is the maximum allowable
value voltage (A C 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.
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.
0.25 to 5.00 sec This delay determines how long the M X waits to apply the
programmed frequency shift to the EUT after the set current
limit level has been exceeded.
0.25 to 5.00 sec This delay determines how long the M X 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 V OLTA GE is applied
