7.1.11. Initialisation to Default Settings
There are two ways to initialise the frequency converter to default: Recommended initialisation and manual initialisation.
Please be aware that they have different impact according to the below description.
Recommended initialisation (via par. 14-22 Operation
Mode
)
1.
Select par. 14-22 Operation
Mode
2.
Press [OK]
3.
Select “Initialisation” (for NLCP select “2”)
4.
Press [OK]
5.
Remove power to unit and wait for display to turn off.
6.
Reconnect power and the frequency converter is reset. Note
that first start-up takes a few more seconds.

7.1.12. RS-485 Bus Connection
One or more frequency converters can be connected to a controller (or
master) using the RS-485 standard interface. Terminal 68 is connected
to the P signal (TX+, RX+), while terminal 69 is connected to the N signal
(TX-,RX-).
If more than one frequency converter is connected to a master, use par-
allel connections.
Illustration 7.9: Connection example.
In order to avoid potential equalizing currents in the screen, earth the cable screen via terminal 61, which is connected to the frame via an RC-link.
Bus termination
The RS-485 bus must be terminated by a resistor network at both ends. If the drive is the first or the last device in the RS-485 loop, set the switch S801
on the control card for ON.
For more information, see the paragraph
Switches S201, S202, and S801
