Bits 0 2 are used to transmit operation commands to the actuator. Only one of
these bits may be set to 1 at any given time. If several bits are set at the same time,
no operation is performed and the following signal is given: Wrong oper. cmd
For operation commands via bit 2 (Fieldbus SETPOINT):
Condition: Position transmitter (potentiometer, RWG, EWG or MWG) installed
in the actuator
If the setpoint is 0 per mil, the actuators runs to end position CLOSED; it runs
to end position OPEN for 1000 per mil .
If the limit of 1,000 is exceeded, the actuator completely runs to end position
OPEN.
To avoid placing too much strain on the mechanics, reversing of direction is
delayed. The default setting in the factory for the reversing prevention time is
300 ms.
Bits 4 through 7 are not used and must be set to 0.
Byte 2: Fieldbus speed setpoint
Byte 2 - Fieldbus speed setpoint in % (value range 0
available for actuators equipped with ACV variable speed actuators controls.
Bytes 3 and 4: Setpoint /(process setpoint, option)
Byte 3 = high byte, byte 4 = low byte.
The setpoint position is transmitted via bytes 3 and 4 (value: 0
position controller.
The value 1,000 corresponds to the maximum setpoint, e.g. end position OPEN.
The value 0 corresponds to the minimum setpoint, e.g. end position CLOSED.
AC 01.2/ACExC 01.2 Profinet
Value Description
1 Operation command in direction OPEN.
0 No command
1 Operation command in direction CLOSE.
0 No command
1 Run to setpoint
Setpoint is provided via bytes 3 and 4.
In combination with a process controller, this bit is
used to select between process controller operation
and OPEN - CLOSE operation.
0 No command
In combination with a process controller, this bit is
used to select between process controller operation
and OPEN - CLOSE operation.
1 Certain indications of the actuator controls can be
reset using this command in selector switch position
Remote control (REMOTE) via the communication
interface (e.g. PTC tripping device and torque fault).
The function of this bit corresponds to the push but-
ton RESET at the local controls.
