disable operation active
State disable operation active is reached when:
• Bit Enable Operation is reset in state Operation enabled.
Power Off:
State Power Off is reached when:
• A mains power failure is detected and the Power Off function has been ac-
tivated in the cu parameters (see chapter 4.4.22).
➢ The states "shutdown operation active“, “disable operation active“ and
"fault reaction active“ are only carried out with the appropriate setting of
the state machine. The behavior in these states is defined in co32.
Changes of the state machine
All possible changes between the different states of the state machine can be
found in the picture in chapter4.1 State machine.
Setting of bit 3 Enable Operation in the controlword can deactivate the Disable
Operation function.
Setting of bit 2 no Qickstop can deactivate Quickstop Reaction Active.
Disable Operation Active can be interrupted by Shutdown Operation Active.
Quickstop Reaction Activecan not be interrupted by Shut Down Active, inde-
pendent of the selected response to the Switch On Bit.
Fault Reaction Active has the highest priority and can interrupt Shutdown Oper-
ation Active, Disable Operation Active and Quickstop Reaction Active .
Exception:
• Fault Reaction Active is interrupted by Shut Down, if shutdown mode is
set as direct shutdown (shutdown option code = „0: disable drive function“
or co32 state machine properties Mode shutdown mode = „0: direct“).
Removal of bit 1 enable voltage always leads to an immediate shutdown of the
modulation.
