11.2 Repairing and replacing units
⇒
In order to get the highest degree of functional safety, it is advisable to
provide the configured drive controller for replacement. See chapter 9
for identification of the drive controller.
⇒
On page 11-4 you will find a fault report that you should copy. Fill in the
fault report thoroughly and completely. The duly completed fault report
helps accelerate the repair process and identify application-related
faults.
⇒
Switch power off to the control cabinet before beginning work. Make
sure that the power supply switch cannot be unintentionally or
inadvertently switched back on.
DANGER
Lethal electric shock caused by contact to live
parts of more than 50 V!
⇒
Check the installation for complete shutoff by testing
the mains terminals for the electronic power and
control system with regard to de-energization.
⇒
Separate or loosen all electrical and mechanical connections (except
for the fixing screws for the device) on the front, top and bottom of the
device.
•
In case of cooling with a duct remove the ducts from the duct
adapters.
•
The cooling agent connections of liquid-cooled devices can be
taken off the device with the cooling system filled. The liquid
cooling agent won’t leak!
CAUTION
Hand injuries caused by heavy drive controller
with sharp-edged housing!
⇒
Use appropriate hoisting gear and protective gloves
for disassembly.
⇒
Loosen the fixing screws on top and bottom of the device (do not
unscrew!). Lift the device off the fixing screws with appropriate hoisting
gear (DKR02: approx. 120 kg, DKR03: approx. 49 kg, DKR04: approx.
150 kg) and take it out.
⇒
Remove the software module from the faulty device (board U5) and
plug it into the replacement device.
Note:
The machine-specific parameters are stored in the software
module!
If you use the previous software module, it is unnecessary to
readjust the drive to the machine!
