• setting up the motor overtemperature protection
• tuning the speed controller
• setting up the fieldbus control.
If an alarm or a fault is generated during the start-up, see chapter
possible causes and remedies. If problems continue, disconnect the main power and
wait 5 minutes for the intermediate circuit capacitors to discharge and check the drive
and motor connections.

Start-up procedure

Before you start, ensure you have the motor nameplate and encoder data (if needed) at hand.
The start-up may only be carried out by a qualified electrician.
The safety instructions must be followed during the start-up procedure. See the
safety instructions on the first pages of the appropriate hardware manual.
Check the installation. See the installation checklist in the appropriate hardware
manual.
Check that the starting of the motor does not cause any danger.
De-couple the driven machine if
• there is a risk of damage in case of an incorrect direction of rotation, or
• a normal ID run
when the load torque is higher than 20% or the machinery is not able to withstand the
nominal torque transient during the ID run.
Connect the control panel to the drive using an
appropriate Category 5E cable.
Switch the power on.
Switch to local control to ensure that external control is
disabled by pressing the LOC REM button on the control
panel. (Local control is indicated by the text "LOC" on the
uppermost row on the display.)
