Analogue signal interruption detection
F741
Analogue signal
interruption – fault
handling mode
Selection 0: deactivated
1: STOP and
AErr
on display
2: STOP without any message on display
3: Inverter continue running with f-min
4: Reserved
Default setting: 0
F742
Threshold for
detection (%)
Range: 1…100 %
Default setting: 50%
Message via digital output (function code
18
)
If
F400
/
F406
set lower than 0.01V interruption detection is deactivated (a minimal value of 1V is recommended)
Detection threshold is referred to lower limits for analogue input signals, set in parameters
F400 /
F406
Overheat warning level
F745
Warning threshold (%)
Range: 0...100%
Default setting: 80
Heatsink over-temperature warning (message via digital output (function code
16
)
Temperature depending PWM reduction
F745
Threshold for automatic PWM reduction °C
Range: 60...72°C
Default setting: 65°C0
F747
Temperature depending carrier frequency
reduction
Selection: 0: deactivated
1: activated
Default setting: 1
With temperature depending PWM frequency-reduction activated
(F747=1)
, inverter will start to decrease PWM frequency
gradually, as heatsink reaches the temperature set in
F746
If PWM frequency is configured for "RANDOM" (
F159=1
), temperature depending PWM adaption is always deactivated
ATTENTION:!! If sinus output filters are used, the automatic PWM reduction function must be deactivated F747=0
Idling detection
F754
Threshold for idling detection (%)
Range: 0...60 sec.
Default setting: 0.5 sec.
F755
Delay time for idling detection (sec.)
Range: 0...60 sec.
Default setting: 0.5 sec.
Message via digital output (function code
20
)
Earth fault detection
F760
Ground short monitoring
Selection 0: disable
1: enable
Default setting: 1
Reversing mode setting
F761=0:
Reversing goes through f=0 (with deathtime
F120
)
F761
Reversing mode (F=0 / F-START)
Selection 0: through F=0
1: through F-start (F109)
Default setting: 0
F761=0:
Reversing goes through f=Start
(F109)
, (without deathtime
F120
)
