Convotherm settings for variable frequency drive
Hello! The ATV12H075M2 variable frequency drive broke (shorted to ground), so we bought a new one. It was bought through an electronics distributor, not Convotherm. So it has just default settings. Anyone knows which settings this needs to operate properly? Addresses, etc.?
As I understand it, it has MODBUS. Default address was 0 (which is broadcast). When I set it to 1, the oven passes the self-tests (no E03.0.1.1 anymore), and when I start the program it heats, but fan doesn’t turn. I also changed:
COnF> FULL> drC > nPr [Rated motor power]: 0.35kW
COnF> FULL> drC > nCr [Rated motor current]: 1.6A (nameplate says 1.6-1.65A), maybe 1.7A but not important at this point.
Besides this, it is with default settings and I’m not sure which settings it needs.
Any help is greatly appreciated.
