Setting Values For Limit-Value Monitors; P360 Response Delay For External Faults And Alarms; P362 Delay Time For The Overvoltage Monitoring; P363 Threshold For The Minimum Line Frequency - Siemens 6RA70 Series Instructions Manual

PNU Description
P360 Response delay for external faults and alarms
The fault message or alarm is not activated on the converter until the
(G180)
appropriate input or corresponding control word bit (as selected in P675,
(G181)
P686, P688 or P689) has been in the LOW state for at least the time period
set in this parameter (see also Section 8, Sheets G180 and G181).
i001: Delay for external fault 1
i002: Delay for external fault 2
i003: Delay for external alarm 1
i004: Delay for external alarm 2
P361 Delay time for the undervoltage monitoring
FDS Activation of the fault message F006 (line undervoltage) is delayed by the
time that can be set in this parameter. During this delay time firing pulses
are output!
Another time which is parameterized for automatic restarting (P086) only
begins after the time set here has elapsed.
P362 Delay time for the overvoltage monitoring
FDS Activation of the fault message F007 (line overvoltage) is delayed by the
time that can be set in this parameter. During this delay time firing pulses
are output!
Another time which is parameterized for automatic restarting (P086) only
begins after the time set here has elapsed.
P363 Threshold for the minimum line frequency
If the line frequency falls below the value set here and does not rise above it
FDS
again within the "restart" time set in P086, the fault message F008 is
activated. As long as the line frequency is below the value set here, the
drive is kept in operating state o4 or o5.
[values < 45.0 Hz can be set in SW 1.9 and later]
CAUTION
Operation in the extended frequency range between 23 Hz and 110 Hz
is available on request.
P364 Threshold for the maximum line frequency
If the line frequency rises above the value set here and does not fall below it
FDS
again within the "restart" time set in P086, the fault message F009 is
activated. As long as the line frequency is above the value set here, the
drive is kept in operating state o4 or o5.
CAUTION
Operation in the extended frequency range between 23 Hz and 110 Hz
is available on request.

10.18 Setting values for limit-value monitors

(see also Section 8, Sheet G187 and G188 of Operating Instructions 6RX1700-0AD**)
n < n min signal
P370 Speed threshold n min
Speed threshold for n < n min limit-value monitor.
FDS
Note:
(G187)
This threshold also affects the sequence of control operations for
"Shutdown", "Fast stop", cancellation of the "Inching" or "Crawling"
command, the "Braking with field reversal" function and the brake control
operation (see Section 9).
P371 Hysteresis for n < n min signal
This value is added to the response threshold if n < n min is active.
FDS
(G187)
n < n comp. signal
