Commissioning of the Frequency Inverter
7.1
Switching on Mains Voltage
After completion of the installation work, make sure to check all control and power
connections again before switching on the mains voltage. If all electrical connections
are correct, make sure that the frequency inverter is not enabled (control inputs
S1IND/STOA and S7IND/STOB open). After power-up, the frequency inverter carries
out a self-test and the relay output (X10) reports "Fault".
After a few seconds, the self-test is complete, the relay (X10) picks up and signals
"no fault ".
If the unit is in "as-delivered" condition or after resetting the unit to the factory set-
tings, the guided commissioning procedure is started automatically. On the control
unit, the “SetUP“ menu from the menu branch CTRL is displayed.
7.2
Setup Using the Control Unit
The guided commissioning of the frequency inverter determines all parameter set-
tings relevant to the required application. The available parameters were selected
based on known standard drive applications. This facilitates the selection of the im-
portant parameters. After successful completion of the SETUP routine, the actual
value

from the VAL menu branch is displayed on the control
unit. Now, the user should check whether further parameters are relevant for the ap-
plication.
Note:
The guided commissioning contains the function for parameter identifi-
cation. The parameters are determined by way of measurement and set
accordingly. You must carry out the guided commissioning procedure
with cool machine
because part of the machine data depends on the
operating temperature.
Warning!
For control of a synchronous machine and successful setting of pa-

first. To do this,
proceed according to the operating instructions for the extension mod-
ule EM-RES installed. Otherwise, personal or machine damage may
occur.
When the unit is in "as-delivered" condition, the guided commission-
ing procedure is started automatically. After successful commission-
ing, the guided commissioning can be carried out again later via the
sub-menu CTRL, and the function can be called again.
Use the ENT key to switch to the CTRL sub-menu.
In the CTRL sub-menu, select the menu item "SEtUP" and con-
firm by pressing the ENT key.

lowing chapter)
If the setup was changed, the hardware and software functionality
will be configured. The message "SEtUP" is displayed again.
Confirm this message by pressing the ENT key in order to continue
the commissioning procedure.
