Lenze i550 Series - Initial Switch-On and Functional Test

Inial switch-on and funconal test
Target: achieve rotaon of the motor connected to the inverter as quickly as possible.
Requirements:
•
The connected motor matches the inverter in terms of power.
•
The parameter sengs comply with the delivery status (Lenze seng).
1. Preparaon
1. Wire power terminals.
2. Wire digital inputs X3/DI1 (start/stop), X3/DI3 (reversal) and X3/DI4 (frequency preset 20 Hz).
3. Do not connect terminal X3/AI1 (analog setpoint selecon) or connect it to GND.

2. Switch on mains and check readiness for operaon
1. Switch on mains voltage.
2. Observe LED status displays "RDY" and "ERR" on the front of the inverter:
a) If the blue "RDY" LED is blinking and the red "ERR" LED is o, the inverter is ready for operaon. The
controller is inhibited.
You can now start the drive.
b) If the red "ERR" LED is lit permanently, a fault is pending.
Eliminate the fault before you carry on with the funconal test.
