10.16 Ramp-function generator
P330 Factor for ramp-function generator times
*
Selection of a factor for the values set in parameters P296, P297, P298,
FDS
P303 to P314 and P542 (ramp-function generator times).
(G136)
0 Factor = 1
1 Factor = 60
i.e. effective ramp-function generator times = values set in
[minutes] instead of in [seconds]

10.17 Setting values for monitoring functions and limits

Setting values for monitoring functions
P351 Threshold for undervoltage trip
If the line voltage drops below a specific value (P078) and does not return to
FDS
the permissible tolerance range within the "Restart time" set in P086, fault
message F006 is activated. The drive dwells in operating state o4 or o5
while the line undervoltage persists.
P352 Source for overvoltage trip
If the line voltage exceeds a specific value (P078) and does not return to the
FDS
permissible tolerance range within the "Restart time" set in P086, fault
message F007 is activated.
P353 Response threshold for phase failure monitoring
If the line voltage drops below the permissible value in operating states of
FDS
≤ o4 and does not return to an "acceptable" value within the "Restart time"
set in P086, fault message F004 or F005 is activated.
The drive dwells in operating state o4 or o5 for the period that the line
voltage remains below the threshold and during the subsequent voltage
stabilization period set in P090.
When a switch-on command is entered, the converter dwells in operating
states o4 and o5 for a maximum total delay period for both states set in
P089 until the voltages in all phases exceed the threshold set in this
parameter before fault message F004 or F005 is activated.
P355 Stall protection time
F035 is activated if the conditions for the "Stall protection" fault message are
FDS
fulfilled for longer than the period set in P355.
When P355=0.0, the "Drive blocked" monitoring function (F035) is
deactivated and alarm A035 is likewise suppressed.
P357 Threshold for tachometer interruption monitoring
F042 is suppressed if the actual EMF value is lower than the value set in
FDS
P357.
The setting is entered as a % of the ideal mean DC voltage value at α =0,
i.e. as a % of P078.001 * 1.35
