Process representation output
Via the process representation output, the master (control) can control the slave (actuator).
Only one operation bit may be set at any given time. If several operation bits are set at the same time, the actuator stops and signals the
fault “wrong command”

Run to nominal value Can only be set if position transmitter
(potentiometer / ESR (options)) is available.
Do not run to nominal value
Bits 3-7 are reserved for extensions and must be set to 0.
Byte 2: Nominal output speed: This byte is not used
Value range: 0..100:
Minimum speed: 0 (actuator runs with min. set output speed)
Maximum output speed: 100 (actuator runs with max. set output speed)
Byte 3: Set point (position) high byte
Conditions Values
Parameter 2 (data code from position
transmitter) = 0
This byte must be set to 0.
Parameter 2 (data code from position
transmitter) = 1
This byte states the higher value part (High byte)
of the nominal value.
Byte 4: Set point (position) low byte
Conditions Values
Parameter 2 (data code from position
transmitter) = 0
Range 0..100
Parameter 2 (data code from position
transmitter) = 1
This byte states the lower value part (Low byte) of
the nominal value.
