10.2 Control via state machine
In the operation mode “control via state machine” (parameter Local/Remote 412 = 1)
the frequency inverter is controlled via
controlword .
State transition 4 to state “Operation enabled” is only possible when:
Motion control configuration (
Configuration 30 = x40):
Î controller release at STOA and STOB is set.
In other configurations (non motion control,
Configuration 30 ≠ x40):
Î controller release at STOA and STOB is set AND (S2IND OR S3IND)
(S2IND = start clockwise/S3IND = start anticlockwise)
The behavior of transition 5 can be set via the parameter State transition 5 392.
Here, free stopping, shutdown via ramp (reversible) or DC braking (see Chapter
"Behavior in transition 5") can be used.

Controlword bits 4, 5, 6 operation mode specific and bit 8 halt are used in motion
control configurations (
Configuration 30 = x40) only.
Statusword bits 12 + 13 operation mode specific are used in motion control configura-
tions (
Configuration 30 = x40) only.
Note: ACTIVE CUBE inverters support an external 24V supply for control logic. Even
if the mains are not switched on the communication between PLC and inverter
can be established.
The bit 4 “Voltage enabled” of the
statusword displays the current state of
the mains power supply.
Bit 4 “Voltage enabled” = 0 signals “no mains voltage” and the state tran-
sision “Ready to switch on” Î “Switched on” is not possible.
Bit 4 “Voltage enabled” = 1” signals “mains voltage switched on” and the
state transition “Ready to switch on” Î “Switched on” is possible.
