Fig. 12-116: CiA-402 state machine
Note:
Some of the CiA-402 states cannot be directly mapped to drive's internal sys-
●
tem state machine. More-over direct control of the drive's power section by
option card is not feasible. The states defined in the CiA-402 state machine
are simplified and mapped as follows.
CiA-402 state
Not ready to switch on
Switch on disabled / Ready to switch on / Switched on Stop
Operation enable
Quick stop active
Fault reaction active / Fault

Quick stop object option code (0x605A) is not implemented.
●
Transition 16 is not supported.
●
Upon reception of Quick stop command the drive automatically transits (12)
●
to "Switch On Disabled" state when the drive stops.
Illegal state transition request is handled as follows:
●
In order to control the drive, the state transitions have to be done in a proper
sequence. If the requested state transition is not appropriate (as defined in
the state chart) then it is termed as "Illegal transition".
