CiA402 State Chart

Description of States
Each state represents an internal reaction by the drive.
This chart will change depending on whether the control word is sent "CMD" or an event
occurs (a detected fault, for example).
The drive state can be identified by the value of the status word "ETA."
State
1- Not Ready to switch on
2 - Switch on disable
3 – Ready to switched on
4 - Switched on
5 - Operation enabled
6 - Quick stop active

Drive internal reaction
Initialization stats. This is a transient state invisible to the communication
network.
The drive is inactive.
The drive is locked, no power is supplied to the motor.
The drive is supplied with AC power but is stationary.
The drive is locked, no power is supplied to the motor.
The drive is supplied with AC power but is stationary.
The drive is locked, no power is supplied to the motor.
The power stage of the drive is ready to operate, but voltage has not yet
been applied to the output.
The drive is running.
The drive is unlocked, power is supplied to the motor.
The drive functions are activated and voltage is applied to the motor
terminals.
If the reference is zero or the "Halt" command is applied, no power is
supplied to the motor and no torque is applied.
"ATN" Auto tuning requires an injection of current into the motor. The drive
must therefore be in state "5 - Operation enabled" for this command.
NOTE: The command "4 - Enable operation" must be taken into
consideration only if the channel is valid. In particular, if the channel is
involved in the command and the reference, transition 4 will take place only
after the reference has been received for the first time.
Emergency stop.
The drive performs a fast stop, after which restarting will only be possible
once the drive has changed to the "Switch on disabled" state.
During fast stop, the drive is unlocked and power is supplied to the motor.
The condition for transition 12 to state "2 - Switch on disabled" depends on
the value of the parameter "Quick stop mode":
If the "Quick stop mode" parameter has the value 0, the drive stops freewheel
and then changes to state "2 - Switch on disabled".
If the "Quick stop mode" parameter has the value 1, the drive stops according
to the slow down ramp and then changes to state "2 - Switch on disabled".
If the "Quick stop mode" parameter has the value 2, the drive stops according
to the quick stop ramp (0x604A) and the changes to state "2 - Switch on
disabled".
Do not set the value 3 to "Quick stop parameter".
If the "Quick stop mode" parameter has the value 4, the drive stops according
to the voltage limit and the changes to state "2 - Switch on disabled".
