Operation manual Profibus PBD 100
23.07.2007
10/36
Time of initiation for the safety operation in 0.1 s.
Indicates the down time of initiation of the net data transmission after which a safety operation will be started. If transmission is restored
during this time no safety operation will be performed.
Parameter 8 “Safety operation”
Default value: 0
0: Actuator remains in its position.
1: Actuator runs CLOSE.
2: Actuator runs OPEN.
3 Actuator runs to the safety position (refer to parameter 9).
If no position transmitter is installed (Parameter 1 = 0), value 3 is not permitted. In this case the parameter set is rejected.
Parameter 9 “Safety position in per mil”
Default value: 0
lowest value: 0 end position CLOSED
highest value: 1000 end position OPEN
Actuator runs to the set safety position. This parameter is only effective if parameter 8 (safety operation) is set to value 3 and if parameter 6
(safety behaviour) is not 0.
Parameter 10 “Output speed safety operation percentage”
Default value: 100
lowest value: 0 (minimum output speed)
highest value: 100 (maximum output speed)
Running speed with which the safety position will be approached.
Only effective if parameter 8 (safety operation) and parameter 6 (safety behaviour) are not set to 0.
Detailed descriptions of the parameters 11 to 14 see subclause 9.2
Parameter 11 “Dead time positioner in 0.1 s”
Default value: 0
lowest value: 0 (actuator reacts immediately)
highest value: 600 (actuator delays reaction by 1 minute max.)
Indicates the time which has to be maintained between two motor starts. In case the controls issue a command before that time, the actuator
delays reaction until dead time has expired.
It must be ensured via the controls that the maximum number of starts of the actuator is not exceeded.
Parameter 12 “Overrun direction OPEN in per mil”
Default value: 5
lowest value: 0 (no overrun in direction OPEN)
highest value: 100 (10 % overrun in direction OPEN)
The motor is switched off as soon as the distance between the actuator position and the nominal position arrives at this value. This is only
valid for operations in direction OPEN. This parameter must be smaller than the value in parameter 14 (max. error in per mil).
Parameter 13 “Overrun direction CLOSE in per mil”
Default value: 5
lowest value: 0 (no overrun in direction CLOSE)
highest value: 100 (10 % overrun in direction CLOSE)
The motor is switched off as soon as the distance between the actuator position and the nominal position arrives at this value. This is only
valid for operations in direction CLOSE. This parameter must be smaller than the value in parameter 14 (max. error in per mil).
Parameter 14 “max. error in per mil”
Default value: 10
lowest value: 1 (0.1% error).
highest value: 100 (10% error).
