Register 256 "Reset"
The actuator supports the following reset/re-initialization behavior:
● Local reset by push-button
● Reset over bus with command "Remote-Reset"
Effect of reset:
● Process values except actual value and setpoint are reset to factory settings.
● Network parameters (register 513...516 and 764...768) are only reset in case of a local
reset. When resetting over the network, the network parameters are retained, as other-
wise communication would be lost.
● Not reset are: Counters and device info.
Register 260/261 "Minimum and maximum position"
Electronic positioning limitation
Register 262 "Actuator runtime"
Read only; positioning time from one stop to another.
Register 513...515 "Backup mode"
The device can be configured to go to a defined state if communication to the controller is
lost.
● Waiting time to recognize communication loss → Register 515
● Reaction:
– Go to a predefined backup position → Register 514
– Deactivate (factory setting): The actuator controls to the last received setpoint, until a
new valid setpoint is received.
Register 516 "Startup setpoint"
The parameter defines a positioning setpoint for the actuator at initial commissioning or after
a power reset, before receiving a new valid setpoint from the controller.
Register 794...766 "Modbus configuration"
Configures the RS-485 address and transmission parameters.
Register 767 "Bus termination"
Defines the electronic switching 120 Ω resistance for bus termination.
Register 768 "Bus config. command"
The "Load" function must be queried in the register within 30 s to save the parameters if pa-
rameters in Registers 764...766 "Modbus configuration" are changed over the bus. Other-
wise, the changes are discarded.
