Resolution 1 RPM.
The speed of the motor at which flow Is
zero and minimum pressure H
MIN
is achieved
should be entered here in RPM. Alterna-
tively, the speed in Hz can be entered in
parameter 22-84 Speed at No-Flow [Hz]. If it
has been decided to use RPM in 0-02 Motor
Speed Unit then parameter 22-85 Speed at
Design Point [RPM] should also be used.
Closing the valves and reducing the speed
until minimum pressure H
MIN
is achieved
determines this value.

The speed of the motor at which flow has
effectively stopped and minimum pressure

is achieved should be entered here in
Hz. Alternatively, the speed in RPM can be
entered in parameter 22-83 Speed at No-Flow
[RPM]. If it has been decided to use Hz in
0-02 Motor Speed Unit then
parameter 22-86 Speed at Design Point [Hz]
should also be used. Closing the valves and
reducing the speed until minimum pressure

be entered here in RPM. Alternatively, the
speed in Hz can be entered in
parameter 22-86 Speed at Design Point [Hz].
If it has been decided to use RPM in

22-87 Pressure at No-Flow Speed
Range: Function:
0 * [ 0 - par. 22-88 ] Enter the pressure H
MIN
corresponding to
Speed at No Flow in Reference/Feedback
Units.
Also see parameter 22-82 Work Point Calculation point D.
22-88 Pressure at Rated Speed
Range: Function:
999999.999 * [ par. 22-87 -
999999.999 ]
Enter the value corresponding
to the Pressure at Rated Speed,
in Reference/Feedback Units.
This value can be defined using
the pump datasheet.
Also see parameter 22-82 Work Point Calculation point C.
22-90 Flow at Rated Speed
Range: Function:
0 * [0 - 999999.999 ] Enter the value corresponding to Flow at
Rated Speed. This value can be defined
using the pump datasheet.
5.2.10 23-0* Timed Actions
Use Timed Actions for actions needing to be performed on
a daily or weekly basis, e.g. different references for working
hours/non-working hours. Up to 10 Timed Actions can be
programmed in the frequency converter. The Timed Action
number is selected from the list when entering parameter
group 23-0* from the LCP. Parameter 23-00 ON Time –
parameter 23-04 Occurrence then refer to the selected
Timed Action number. Each Timed Action is divided into
an ON time and an OFF time, in which 2 different actions
may be performed.
The clock control (parameter group 0-7* Clock Settings) of
Timed Actions can be overridden from Timed Actions Auto
(Clock Controlled) to Timed Actions Disabled, Constant OFF
Actions or Constant ON Actions either in 23-08 Timed
Actions Mode or with commands applied to the digital
inputs ([68] Timed Actions Disabled, [69] Constant OFF
Actions or [70] Constant ON Actions, in parameter group
5-1* Digital Inputs.
