Replacing,
addressing and parametrizing frequency converters [2]
The frequency converters control the speed of travel and
hoist motors.
A faulty frequency converter can be removed and replaced as
an individual module. For this purpose, it is connected with plug-in connections
or terminal blocks.
Setting the
device address
The frequency converter is controlled by the central PLC via
a device address. The device address can be automatically or manually set.
The device address is a digital
unique address of each CAN bus device in the CAN bus network, via which the PLC
and the respective CAN bus device exchange data. Each CAN bus device must have
its own unique device address. If two CAN bus devices inadvertently have the
same device address there will be a conflict and a fault is displayed.
The bit rate is the speed with which the data is exchanged.
See also Overview: Device addresses,
page .
Device address and bit rate are correctly set:
If the frequency converter is already correctly set (correct
device address and bit rate), it can be directly installed.
● As the
device address and bit rate are correctly set, the PLC finds the CAN bus device
at the expected device address.
Setting device address of the PLC automatically:
If the base address is set on the frequency converter, the
correct device address is automatically set by the PLC.
● The PLC doesn't find a component
at the expected device address, instead it finds a CAN bus device with a base
address.
● The PLC
converts the base address of the CAN bus device to the expected device
address.
Setting device address and bit rate manually:
If the device address or bit rate is incorrectly set at the
frequency converter, it must be manually set.
Only with frequency
converter ATV320
Removing a jumper:
It is possible that a jumper is used on the frequency
converter ATV320 which must be removed so that the frequency converter can
function correctly.

Restarting ABUControl:
Switch off the crane. See Switching off the
crane.
Wait for about 1 minute.
Switch the crane on.
Replacing
frequency converters
Switch off the crane. See Switching off the crane.
Remove or disconnect connection cables from
the faulty components.
Remove and replace faulty components.
Plug in or connect the connection cables
again.
Switch the crane on.
After replacement, the frequency converter must be
reparametrized.
For this work step, access from a laptop or tablet computer
to KranOS is necessary. The user "Abnahme" (commissioning) (user level ‚[2]) or
"Service" (user level [1]) must be logged in.
