4.2.3 Basic Operation - 10 Step Guide
The basic method of setting up the inverter for use is described below. This method uses a digital frequency setpoint and requires only
the minimum number of parameters to be changed from their default settings. It assumes that a standard Siemens four-pole motor is
connected to the inverter
(see section 4.2.1 if another motor type is being used)
.
Step/Action
Button
Display
1.
Apply mains power to the inverter.
The display will alternate between the actual frequency (0.0 Hz) and the requested
frequency setpoint (5.0 Hz default).
2.
Press the parameterisation button.
3.
Press the
D
button until parameter P005 is displayed.
4.
Press P to display the present frequency setpoint (5 Hz is the factory default setting).
5.
Press the
D
button to set the desired frequency setpoint
(e.g. 35 Hz).
6.
Press P to lock the setting into memory.
7.
Press the
Ñ
button to return to P000.
8.
Press P to exit the parameterisation procedure.
The display will alternate between the present output frequency and the frequency
setpoint.
9.
Start the inverter by pressing the RUN button.
The motor shaft will start to turn and the display will show that the inverter is ramping up
to the setpoint of 35 Hz.
Note
The setpoint will be achieved after 7 seconds (default ramp-up time, defined by P002 is
10s to reach 50 Hz, the default maximum motor frequency, P013).
If required, the motor’s speed (i.e. frequency) can be varied directly by using the
D
Ñ
buttons. (Set P011 to 001 to enable the new frequency setting to be retained in memory
during periods when the inverter is not running.)
10.
Switch the inverter off by pressing the STOP button.(see section 5.4)
The motor will slow down and come to a controlled stop.
Note
Full stop will be achieved after 7 seconds (default ramp-down time, defined by P003 is 10 s
from 50 Hz, the default value P013).
