FtU
T
M Time delay before automatic start for the
underload fault
0 to 6 min 0 min
If Atr = YES the drive restarts automatically after an underload fault ULF once this time delay has
elapsed.
Minimum time permitted between an underload being detected and any automatic restart.
In order for an automatic restart to be possible, the value of Maximum restart time tAr page 91
must
exceed that of this parameter by at least one minute.
Visible only if Application underload time delay ULt above is not set to nO.
MdE
M Selecting the operating mode
nO
v nO: single variable mode
v YES: single variable mode with auxiliary pump
When MdE = YES, output LO1 is forced to PMP (see page 53
).
Visible only if PID feedback assignment PIF page 72
is not set to nO.
FOn
T
M Starting frequency of the auxiliary pump
0 to tFr HSP
Above this frequency and after the pump starting time delay tOn,
the auxiliary pump starts.
Visible only if Selecting the operating mode MdE above is not set to nO.
tOn
T
M Time delay before starting the auxiliary
pump
0 to 999.9 s 2 s
This time is necessary to avoid the effects of transient pressure fluctuation and thus prevent oscillation
(pump starting/stopping).
Visible only if Selecting the operating mode MdE above is not set to nO.
rOn
T
M Ramp for reaching the auxiliary pump
nominal speed
0 to 999.9 s 2 s
Visible only if Selecting the operating mode MdE above is not set to nO.
FOF
T
M Auxiliary pump stopping frequency
0 to tFr 0 Hz
Below this frequency and after the time delay for stopping the auxiliary pump tOF, the pump stops.
Visible only if Selecting the operating mode MdE above is not set to nO.
T
Parameter that can be modified during operation or when stopped.
