Definition of the bits
Tripping of safety relay
Resetting of speed controller
Assigning of LOCAL commands
Assigning of LINE commands
Cancellation of communication control
Commands (read and write)
Run / stop command
Frequency reference sign
DC braking command
Freewheel stop command
Fast stop command

* These bits cause the action given when written at 1 They are reset to zero by the speed
controller Writing them at 0 has, therefore, no effect and they will always read 0.
Causes the ATV-45 2s safety relay to open, and as a result, the switching off of the
controller, If the relay contact Is used to maintain the line contractor.
Causes fault acceptance and resetting of the ATV-45 2 safety relay only If the fault could
be corrected and has disappeared.
Puts the ATV-45 2 in LOCAL mode, this can only be controlled from Its terminal (logic and
Puts the ATV-45 2 in LINE, this waits for its commands from the serial link.
When the speed controller is In LINE mode exchange monitoring is carried out
permanently, If the ATV 45 2 does not receive at least one character every second, the
SLF fault will appear.
The setting to state 1 of bit B4 cancels this control This possibility is reserved for fine
adjustment phases and Is not recommended during operation for safety reasons.
1 = run, 0 = stop.
Frequency reference signal 0 = positive, 1 = negative.
Reversing the rotation direction can be achieved by changing the bit state. or by supplying
an opposite frequency reference sign in word W19.
Brake control by positioning the bit at 1 Has priority over RUN bit.
Freewheel stop control as soon as the bit Is set to 1 Has priority over RUN bit.
Fast stop control (deceleration ramp divided by 4) Has priority over RUN and CAL bit.
