Register 262 "Actuator runtime"
Read value only; positioning time from one stop to another.
Register 263 "Positioning signal characteristic between Y and U"
Depending on the valve type, a logarithmic characteristic can be compensated using this
function, in order to achieve a linear input/output signal (see Modbus registers [➙ 7]).
Register 264 "Tolerance blockage monitoring"
If the setpoint does not reach the tolerance limit set within this parameter, bit 04 is set in
register 769 and can be used for alarming in the building automation system.
Register 513...515 "Backup mode"
In case the communication to the controller is lost, the device can be configured to go into a
defined state.
● Waiting time to recognize communication loss → Register 515
● Reaction:
– Go to a predefined backup position → Register 514
– Deactivated (factory setting): The actuator controls to the last received setpoint, until
a new valid setpoint is received.
Register 516 "Startup setpoint"
In this parameter, a setpoint can be defined, which the actuator moves to at initial
commissioning or after a power reset, before receiving a new valid setpoint from the
controller.
Register 794...766 "Modbus configuration"
Configuring the RS-485 address and transmission parameters.
Register 767 "Bus termination"
Electronically switchable 120 Ω resistance for bus termination.
Register 768 "Bus config. command"
If the parameters in registers 764...766 “Modbus configuration” are changed via bus, they
are only saved of the function “Load” is called within 30 s in this register. Otherwise, all
changes are discarded.
Register 769 "Status"
In register 76, the bits are set as described in the table below, in order to reflect the
respective status information.

Bit 00 1 = Not available Bit 06
1 = Not available
Bit 01 1 = Backup mode active Bit 07
1 = Not available
Bit 02 1 = Not available Bit 08
