How can resolve problem A2002 OVERVOLTAGE Alarm in ABB ACS550 Drive ?
Overvoltage controller is active. Check for and correct:
• Static or transient overvoltages in the input power supply.
• Insufficient deceleration time (parameters 2203 DECELER TIME 1 and
2206 DECELER TIME 2).
Check input supply voltage.
If input supply is ok then check DC voltage in parameter group 1
Parameter 0107 - .... DC voltage.
If all are ok then increase de-acceleration time
Parameter 2203 - ......
Please also share above reading and what is condition of fault means fault comes when you stop drive or comming continuously.
