Remove power from the drive and wait for the charge lamp to be completely extinguished. Wait at least five additional minutes for the drive to be
completely discharged. Measure the DC BUS voltage and verify that it is at a safe level.
Reinstall the operator keypad and terminal cover.
Set parameters n003, n004 and n035 to their appropriate values

• Check whether the address set in
the PROFIBUS-DP Master differs
from the address of the option unit.
• Check that the master is functioning
properly.
• Check that the termination resistor
is correctly connected to the
communication line.
• Check whether the communication
line is correctly connected
(disconnected or poor connection).
