It sets the pressure that determines the end of the pipe filling
process. The sleep function of the drive is disabled during pipe filling
process. Once the pipe filling process has finished, the drive goes to
the stage of setpoint ramp.
Note:
Default units of measurement which are displayed depend on
the selected engineering units.
YES
4 FILL TIM=15m

G25.7.4
/ Safety
time for pipe
filling process
OFF=0,
1 – 9999min
15m
Setting of a safety time to force the end of the pipe filling process.
The condition that is met before (pressure or time) will force the end
of the pipe filling process, changing the equipment from the filled
status (FILL) to setpoint ramp (RAMP).
Note:
If this time is set to ‘0’, the drive will not execute the pipe
filling process.
YES
5 SPT RAMP=1.0Bar / s
G25.7.5
/
Setpoint ramp
0.01 – 326
Engineering
Units / s
1.0Bar / s
Setting of the ramp applied to increase the setpoint.
After finishing the pipe filling process, or if this process has not been
realized from the beginning, the drive will adjust the setpoint value
to the present value of the feedback signal provisionally. Then, the
setpoint will be increased according to the ramp set in this
parameter up to a 5% below the real setpoint selected by user. In
that moment, the real regulation will start. During the setpoint ramp,
the drive cannot go to sleep by no demand.
By setting a slow setpoint ramp, a smooth increase of the motor
speed is get.
Note:
Default units of measurement which are displayed depend on
the selected engineering units.
YES
