5.3 Start-up of the pump-motor unit
The description of how to change pre-set parameters using the hand-held keypad starts on page 34.
NOTE
 When no setpoint has been entered, the drive rotates with the minimum frequency set under
C0010!
 The setpoint offset set under C0140 is stored and will be active at each switch−on.
 The setpoint offset set under C0140 has an additive effect on all other setpoints!
 This effect can be used, for example, to set speeds between fixed speeds:
– Fixed speed via terminal = 67 Hz (4000/min)
– C0140 = -7 Hz
–
Resulting speed = 60 Hz (3600/min)
Switch-on sequence Note
1. Connect keypad.
2. Ensure that controller inhibit is active after
mains connection. misc00
Terminal X3/28 = LOW
3. Open the shut−off device in the inlet line or in
the pressure line..
4. Switch on the mains.

5. The keypad is in “Disp” mode after approx. 2
s and indicates the setpoint offset (C0140). Set
6. Change to the  mode with  in order to
set drive parameters.
0I40 is blinking in the display .
7. Press  . Thus, you skip the display codes
for output frequency (C0050),
motor voltage (C0052) and
apparent motor current (C0054).
8. Set the minimum output frequency (C0010).
Default setting: 10.00 Hz (600/min)
After controller enabling, the
motor at least rotates with the
frequency set under C0010!
9. Set the maximum output frequency (C0011).
Default setting: 86.00 Hz (3000/min)
