Illegal Transition 
After initiation of a drive by either power on or NMT node reset, the drive automatically 
performs transitions 0 and 1 to the SWITCH ON DISABLED state. The controlword can 
then be used to cause any of the transitions defined previously. If a transition is illegal 
(such as requesting a QUICK STOP in a FAULT state), the controlword is rejected with 
abort code 0609 0030, “Value range of parameter exceeded.” If an RPDO is used to 
control the drive, an RPDO style emergency is transmitted with the error code. The 
emergency structure and meaning is illustrated in the 
SimplIQ
 CANopen Implementation 
Manual. This emergency can be masked in accordance with object 2F21h. In case of an 
illegal transition, bit 7 in the statusword
 (warning) is set for at least the next 
transmission of this statusword
. The bit is after a legal transition of the controlword
  The resolution for statusword transmission is approximately 3 milliseconds. Events 
that are modified during this time are sensed and responded to, but no notification 
of them is made by the statusword
 
Object 0x6040: Controlword
