Actuator controls AUMA MATIC AM/ AMExB/ AMExC
Modbus
36
Parameter 10: not used
For detailed descriptions of parameters 11 to 14, please refer to
subclause 12.2
Parameter 11 "Dead time positioner in 0.1 s"
Indicates the dead time which has to be maintained between two motor
starts. In case the Modbus master issues a command before that time, the
AUMA MATIC delays the actuator reaction until dead time has expired.
Holding Register Offset: 0x400A (hexadecimal), 16394 (decimal)
The Modbus master of the controls must ensure that the
maximum number of motor starts of the actuator is not
exceeded.
Default value: 0
minimum value: 0 (actuator reacts immediately)
maximum value: 600 (actuator delays reaction by 1 minute max.)
Parameter 12 "Overrun direction OPEN in per mil"
The motor is switched off as soon as the distance between the actuator
position and the nominal position reaches this value. This is only valid for
operations in direction OPEN.
This parameter must be lower than the value in parameter 14 (max. error in
per mil).
Holding Register Offset: 0x400B (hexadecimal), 16395 (decimal)
Default value: 5
minimum value: 0 (no overrun in direction OPEN)
maximum value: 100 (10 % overrun in direction OPEN)
Parameter 13 "Overrun direction CLOSE in per mil"
The motor is switched off as soon as the distance between the actuator
position and the nominal position reaches 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).
Holding Register Offset: 0x400C (hexadecimal), 16396 (decimal)
Default value: 5
minimum value: 0 (no overrun in direction CLOSE)
maximum value: 100 (10 % overrun in direction CLOSE)
Parameter 14 "Max. error in per mil"
The actuator will only be restarted if the distance between the nominal posi-
tion and the actual position is higher than this value.
Corresponds to the outer dead band.
This parameter must be higher than the value in parameter 12 (overrun in
direction OPEN) and parameter 13 (overrun in direction CLOSE).
The parameter must be set sufficiently high to ensure a
stable function of the positioner. If the value is set too low,
the actuator moves continuously within nominal value range
which will result in reducing the life time of the actuator.
Holding Register Offset: 0x400D (hexadecimal), 16397 (decimal)
Default value: 10
minimum value: 1 (0,1 % error).
maximum value: 100 (10 % error).
