Control / Reference Value
The device control commands are triggered by the following bit combinations in the Control Word:
Control Word

Bit 7 Bit 3 Bit 2 Bit 1 Bit 0
Transitions
Reset Fault Enable
Operation
Quick Stop Enable
Voltage
Switch On
Shutdown X X 1 1 0 2, 6, 8
Switch On X 0 1 1 1 3
Switch On X 1 1 1 1 3
Disable Voltage X X X 0 X 7, 9, 10, 12
Quick Stop X X 0 1 X 7, 10, 11

1 x x x x 15
"X" means any value.
Transition 3 (Command "Switch On") is only processed if Bit 4 "Voltage enabled" in the Status Word is
set.
The status word reflects the operation state.

"X" means any value.
Bit 7 "Warning" can be set at any time. It signals a device-internal warning. The active warning can
be read out from the Warning Status with Parameter
Warnings
270.
Bit 9 "Remote" is set if the operation mode "Control via Statemachine" (
Local/Remote
412 = 1) is
set, and the Controller Release is switched on.
Logical combination of the digital control signals:
STO = (STOA and STOB) AND (Start Right OR Start Left).
The frequency inverter can only be controlled, if the logical combination is true. The logical inputs for
Start Right and Start Left can be directly linked to "On" or "Off" (Parameter
Start Clockwise
68 and
Star Anticlockwise
69).
Bit 10 "Reference frequency reached" is set when the specified reference value is reached. In the
special case of power failure regulation, the bit is also set when the power failure regulation reaches
the frequency 0 Hz (see frequency inverter operating instructions). For "Reference value reached"
there is a hysteresis (tolerance range) which can be set via Parameter
Reference Value Reached:
Hysteresis
549 (see frequency inverter operating instructions).
Bit 11 "Limit value reached" indicates that an internal limit is active. This may be the current limit,
the torque limit or the overvoltage control. All functions result in the reference value being left or not
reached.
