Initial switch-on and functional test

Initial switch-on and functional test
Target: achieve rotation of the motor connected to the inverter as quickly as possible.
Requirements:
• The connected motor matches the inverter in terms of power.
• The parameter settings comply with the delivery status (Lenze setting).
1. Preparation
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 selection) or connect it to GND.
2. Switch on mains and check readiness for operation
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 off, the inverter is ready for operation. 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 functional test.
