Control / Reference Value
The device control commands are triggered by the following bit combinations in the Control Word:
Command
Shutdown
Switch On
Switch On
Disable Voltage
Quick Stop
Disable Operation
Enable Operation
Reset Fault
"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.
State
Switch On disabled
Ready to Switch On
Switched On
Operation enabled
Quick Stop active
Error Reaction active
Error
"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
Bit 9 "Remote" is set if the operation mode "Control via Statemachine" (
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 Anticlockwise
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
terisis
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.
