Controller states Meaning
NOT READY TO SWITCH ON The controller is being initialized and is not yet
ready to operate. It then switches automaticaly to
the state "switch-on disabled".
SWITCH ON DISABLED The controller is inhibited (RSP) and waits for
comand 2 (shutdown).
READY TO SWITCH ON The controller is inhibited (RSP) and waits for
command 3 (switch on).
SWITCHED ON The controller is inhibited (RSP) and waits for
command 4 (operation enabled)
OPERATION ENABLED The controller is enabled (RFR). In this state, a
pulse inhibit is possible any time.
MALFUNCTION REACTION
ACTIVE A fault (TRIP) was recognized and an error
response initiated (e.g. controlled deceleration).
MALFUNCTION The controller is in a state of error (TRIP).
QUICK STOP ACTIVE In the state "OPERATION ENABLED" the
command "quick stop" was given. The controller is
decelerated in a controlled way (quick stop ramp).
After deceleration, the controller changes
automatically to "SWITCH ON DISABLED".
Commands Meaning
COMMAND 2,6,8
(Shutdown)
(CONT-Bit0 = 0)
Command to change from different states to the
state "READY TO SWITCH ON".
COMMAND 3
(Switch on)
(CONT-Bit0 = 1)
Command to change to the state "SWITCHED
ON".
COMMAND 4
(Operation enabled)
(CONT-Bit3 = 1)
Command to change to the state "OPERATION
ENABLED". Controller inhibit is deactivated.
COMMAND 5
(Disable operation)
(CONT-Bit3 = 0)
Command to change to the state "SWITCHED
ON". Controller inhibit is released.
COMMAND 7,9,10,12
(Disable voltage)
(CONT-Bit1 = 0)
Command to change to the state "SWITCH ON
DISABLED". Controller inhibit is released.
COMMAND 7,10,11
(Quick stop)
(CONT-Bit2 = 0)
Command to change to the state "SWITCH ON
DISABLED".
If the controller was enabled, the controller is
decelerated in a controlled way (quick stop ramp).
COMMAND 13
(Malfunction/TRIP)
The controller has recognized an error.
In case of certain faults, a controller deceleration
may be necessary (depending on the controller).
Once completed, the controller changes to the
state "MALFUNCTION".
COMMAND 14
(Reset malfunction/TRIP)
(STEU-Bit7 0->1)
Command to acknowledge a fault. The controller
changes to the state "SWITCH ON DISABLED" if
an error is no longer recognized.
