The inverter is switched on in the following steps:
●
Switch on the line voltage
– The power supply inside the inverter switches on,
– the DC link is still not precharged.
●
Switch on the inverter, e.g. at the operator panel or with STARTER
– By issuing the ON/OFF command (ON button at the IOP or p0840 = 1 using
STARTER).
– The DC link is now precharged (this takes approx. 4 s).
●
depending on the parameter assignment, the inverter pulses must be separately enabled
- and the inverter then accelerates the motor up to the selected speed.
