Its generally in every application needed to read out the actual drive state (CIA Get State) for "OPERATIONAL" at first, before any function block will be called !
The CIA Get State function block has to be called cyclic and the Enable input must be toggled! Please see attached demo program.
This is needed especially when the drives will be switched on after the PLC has booted otherwise the PLC goes into Nodeguard error, and the MC_Power for Lexium 23
remains in state 991.
