ACS800 CONTROL WORD INFORMATION
In PLC logic, when we use profibus adapter then we use some values like 1151, 1143, 1142. and then move it to the vfd control word.
my question is from where we get this value? what is the meaning of that value?
i have gathered some information from manual, but yet it is not clear to me. plese give details information.
1142 dec is Bit 1,2,4,5,6 and 10 true binary (Starting from bit 0). That is the normal starting state in remote operation.
1143 is with bit 0 set to True. It is the "On Command". At this point, if the drive was Ready On, it will proceed to Ready Run.
1151 is with bit 3 set to true, it is the "Run Command". The drive will respond with Ready Ref which means it is ready to follow a reference.
Please refer to the details in the corresponding manual for the drive. Attached is a link to the standard firmware manual. Page 211 shows the main control word bits in standard firmware. The bit order are same or similar in other firmware as well.
