(
Stop!
Special commissioning procedure after long−term storage
If controllers are stored for more than two years, the insulation
resistance of the electrolyte may have changed.
Possible consequences:
ƒ During initial switch−on, the DC−bus capacitors and hence the
controller are damaged.
Protective measures:
ƒ Form the DC−bus capacitors prior to commissioning.
Instructions can be found on the Internet (www.Lenze.com).
)
Note!
ƒ Keep to the switch−on sequence described.
ƒ The chapter "Troubleshooting and fault elimination" helps
you to eliminate faults during commissioning.
To avoid injury to persons or damage to material assets ...
... before the mains supply is connected, check:
ƒ The wiring for completeness, short circuit and earth fault.
ƒ The "EMERGENCY STOP" function of the entire system.
ƒ The in−phase connection of the motor.
ƒ The correct connection of the resolver or incremental encoder to
prevent the motor from rotating in the wrong direction.
... check the setting of the most important drive parameters before enabling
the controller:
ƒ Is the U/f rated frequency adapted to the motor circuit configuration?
ƒ Are the drive parameters relevant for your application set correctly?
ƒ Is the configuration of the analog and digital inputs and outputs
adapted to the wiring?
