4.4.22.6 Figure in the drive state machine
Since the power-off function is active while the CDM is decoupled from the setpoint
setting, the power-off function is displayed as a separate state in the drive state
machine.
A change into the state power-off-active (st00 bit 14 and st12 value 13) can be
done from the following states:
• Operation enabled
• Shutdown active
• Disable operation active
• Quickstop active
It is not possible to change from "fault reaction active" state to power-off.
When a system recovery is detected, the following state transitions are possible:
• Operation enabled (if the restart speed limit has not fallen below yet)
• Power – off active (drive continues deceleration and completes power-off
function)
The following state transitions are possible when the power-off function has been
terminated:
• Fault (after expiry of the deactivation time)
A change to the state "Switch on disabled" can be made at any time using the com-
mand "Disable Voltage".
