The bit definitions of VFD operating status word 3 are shown as following table:
1. Some instructions
1.For function code 0x10 and 0x43,when rewrite multiple continous function codes,if any one of the function
codes is invalid for write operation,then it will return error information and all of the parameters can’t be
rewritten.When rewrite multiple continuous control parameters,if any one of the parameters is invalid for write
operation, then it will return error information and this parameter and others behind can’t be rewritten,but other
parameters before this parameter can be rewritten normally.
2.For some special function code,Using 0x06 and 0x41 or 0x10 and 0x43 are the same function,in write
operation,the parameters can be saved after power failure.
