Description of user parameters
Parameter 1 "position transmitter"
Default value (standard setting): 1
0: The actuator does not have a position transmitter.
1: The actuator is equipped with a potentiometer without RWG.
2: The actuator is equipped with an ESR 0-20 mA. For this position transmitter, the monitoring of signal interruption is not active.
3: The actuator is equipped with an ESR 4-20 mA.
For this position transmitter, the monitoring of signal
interruption is active.
Parameter 2 "Data code position transmitter"
Default value: 0
0: 0 to 100 percent, resolution is 1%
The value of the position transmitter is stated in byte 4 of the process representation input. Byte 3 is fixed to value 0. The set point is
determined via byte 4 of the process representation output. Byte 3 has to be set to 0.
1: 0 to 1000 per mil, resolution is 0.1%
The value of the position transmitter is read with bytes 3 and 4 of the process representation input.
The set point is determined via bytes 3 (high byte) and 4 (low byte) of the process representation output.
Parameter 3 "Reversing prevention in ms"
Default value: 200
lowest value: 100 (0.1 s)
highest value: 1000 (1 s)
Parameter for setting of the pause time in between a change of direction.
If necessary, adjust the value to the mechanics to prevent destruction
through a change of direction performed too fast.
Parameter 4 "Redundancy"
Default value: 0
0: no cable redundancy (only the first channel is used for communication).
1: cable redundancy switched on (first and second channel cabled) The watchdog must be activated, otherwise the parameter set is rejected
by the DP slave.
Parameter 5 "Time for channel changing in 0.1 s"
Default value: 50
lowest value: 50 (5 s)
highest value: 6000 (10 min)
States the time after which the channel is changed if no net data are transmitted (no state 'Data Exchange' or DP-Fail-Safe). This parameter
is only effective if the cable redundancy (parameter 4) is switched on.
Parameter 6 "Safety behaviour"
Default value: 0
0: Safety behaviour switched off (parameter 7,8,9 insignificant)
1: Simple safety behaviour switched on. A safety operation will only be started if a connection to the master (net data transmission) was
already available.
2: Extended safety behaviour switched on.
If extended safety behaviour is switched on, a safety operation can be triggered immediately after the actuator is
switched on.
Safety operation on failure of connection (no status Data_Exchange or DP-Fail-Safe). The parameters set in the most recent connection also
apply to the safety behaviour after an interruption in the supply voltage. If the parameter is set back to values 1 or 2, the watchdog must to
be activated, otherwise the parameter set is rejected by the DP slave.
Parameter 7 "Time of initiation safety operation 0.1 s"
Default value: 30
lowest value: 0 (actuator reacts immediately)
highest value: 12000 (actuator reacts after 20 minutes)
