Commissioning
The purpose of commissioning is to adapt the inverter as part of a machine with a variable-speed drive sys-
tem to its drive task.
Important notes
DANGER!
Incorrect wiring can cause unexpected states during the commissioning phase.
Possible consequences: death, severe injuries or damage to property
Ensure the following before switching on the mains voltage:
▶ Wiring must be complete and correct.
▶ Wiring must be free of short circuits and earth faults.
▶ The motor circuit configuration (star/delta) must be adapted to the inverter output voltage.
▶ The motor must be connected in-phase (direction of rotation).
▶ The "emergency off" function of the overall system must operate correctly.
DANGER!
Incorrect settings during commissioning may cause unexpected and dangerous motor and system move-
ments.
Possible consequences: death, severe injuries or damage to property
▶ Clear hazardous area.
