11.2 Control via state machine
In the operation mode “Control via state machine (Local/Remote 412 = 1), the fre-
quency inverter is addressed via the control word of the state machine.
Transition 4 to status “Operation enabled” is only possible:
−
If, in a configuration for positioning control (parameter Configuration 30
the controller release is set via STOA and STOB,
If, in other configurations (parameter Configuration 30 ≠
x40) the controller
release is set via STOA and STOB and if one of the digital inputs S2IND or S3IND
is set. (Typically: S2IND = Start clockwise/S3IND = Start anticlockwise)
Parameter Control word 410 is applicable to the frequency inverter if parameter Lo-
cal/Remote
412 is set to “1 – Control via statemachine”.

Bits 9 … 15 are used depending on the configuration and on
Mode of Operation.
Control word
bits 4, 5, 6
operation mode specific
and bit 8
halt
are used in motion
control configurations (Parameter Configuration 30 = x40) only.
The actual value parameter Status word 411 shows the current operating status.
