change acs510 drive direction in modbus
Tnx for your support about my previous question
Now i need a way to change drive direction in abb drv lim or full modbus except Change reference frequenc.
Which one bits & cw specify drive direction in run mod and What number to start the drive should be written in cw 400001
Please give me a clear explanation
This is my first try to install abb driver in modbus
perhaps you have not read the instructions of my app well and in general, if you do not know the rules of regulation in ModBus it becomes quite difficult to be able to give you a clear instruction to do it, in this little space
In the CW you are going to set, as indicated also in the drive manuals, the start command is 47F in hex and to stop the drive 47E is used.
In my app I used 1150 to stop and 1151 to start, it's the same, but in decimal, not in HEX format.
The direction changes with the REF value, i.e. up to 20000 you will have the rotation in one direction, if you increase this value the drive starts to turn in the opposite direction.
