5.1 Before you start
Tip!
The controller is factory−set to drive the following four−pole standard asynchronous motors:
– 230/400 V, 50 Hz
– 280/480 V, 60 Hz
– 400 V, 50 Hz
Maintain the switch−on sequence. ( 5−6)
In the event of an error during commissioning please see the "Troubleshooting and fault
elimination" chapter: ( 8−1)
Check ...
... before the mains voltage is connected
the wiring for completeness, short circuit, and earth fault
If no function module is used (delivery status):
– Has the FIF cover been mounted?
If the internal voltage source X3/20 of the standard I/O is used:
– Are the terminals X3/7 and X3/39 bridged?
... the most important drive parameters settings before the controller is enabled
Has the V/f rated frequency been adapted to the motor circuit configuration? ( 7−5)
Have the configuration of the analog inputs and outputs been adapted to the wiring? ( 7−57)
Have the configuration of the digital inputs and outputs been adapted to the wiring? ( 7−68)
Are the drive parameters relevant for your application set correctly?
If required, use the keypad or PC to adapt them. ( 6−1 ff)

( STOP!
Special commissioning procedure after long−time storage
If controllers have been stored for more than 2 years, their DC−bus capacitors may
have dried out.
Possible consequences:
l The DC−bus capacitors and thus the controller will be damaged at the first
switch−on.
Protective measures:
l Anodize the DC−bus capacitors before commissioning. A detailed set of
instructions can be downloaded from the Internet (www.Lenze.com).
