Function description
Register 1/3 "Setpoint/actual value"
The controller setpoint for the position to move to, 0...100 % stroke/angle of rotation, scal-
ing 0.01, i.e. 0 % = 0 and 100 % = 10000
The actual value reported by the device, with the same scaling.
Register 256 "Restarting the device"
Restarting by:
● resetting power (turning operating voltage off and on)
● Sending "ReInitDevice" command.
⇒ Actuator restarts and sets all process values except actual value (= 50%) and setpoint (=
startup setpoint) to factory settings.
Register 256 "Self-test"
When triggered, the self test drives the actuator to the detected limits and sets the flags in
register 769 according to the result (bit 09 = 1 "failed" or bit 10 = 1 "passed").
The self-test fails, if the limits were not reached from the lower end (equates to a jam). Ex-
ceeding the min/max values does not fail the self-test.
The self-test can only be performed, if bit 04 = 0 in register 769 "Status", in other words,
there is currently no blockage or manual operation
