Brett replied to Gert's topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareGert, im doing a similar application with an ABB ACQ580 - Fena-21... in your logic, you have vector length a 1. which makes sense in the logic that youve presented. Did writing 1151 start the drive and 1150 stop the drive? Did you read or write any more data to/ from the drive? in my application, im looking to also send a speed reference. Would i just increase my vector length to read or write to another register in the drive? Thanks in advance!
