Hi,
New to this so please bear with me.
I have this controlling a Netzsch Progressive cavity pump at 30Hz and the pumps motor is rated at 21A and is running quite hard at 18A.
Recently we are getting VSD alarms that trip the pump out. When I look at the alarms I get 64- Drive OL and straight after 169- PWM Freq reduced.
I've seen a member mention to check parameter P413- Mark OL Factor and set that to 125%.
Can I change this parameter via the HIM or do I need to get software and connect up to it?
Should there be anything else I should try for these alarms?
Appreciate your time
