Additional settings
P no. Parameter name
p0015 = 21 Drive device macro
Select the I/O configuration (USS fieldbus)
p0791[0 ... 1] Fieldbus analog outputs
Parameter to interconnect the analog outputs for control via the fieldbus
p2030 = 5 Fieldbus telegram selection
5: BACnet
p2020 Baud rate
Factory setting = 9600 bit/s
p2024[0 ... 2] Processing times
p2024 [0]: 0 ms ... 10000 ms, maximum processing time (APDU timeout), factory setting = 1000 ms,
p2024[1 ... 2]: No significance for BACnet
p2025[0 ... 3] BACnet communication parameter
p2025 [0]: 0 ... 4194303: Device object instance number,

p2026[0 ... 74] Setting of the COV_Increment
(COV = change of values) 0 ... 4194303, factory setting = 1
COV_Increment: Changes the value of the "present value" of an object instance for which the server
transfers an UnConfirmedCOV_Notification or ConfirmedCOV_Notification.
You can use these parameters to set for which inverter value changes an UnConfirmed-
COV_Notification or ConfirmedCOV_Notification result is sent.
The factory setting 1 means that the inverter sends an UnConfirmedCOV_Notification or Confirmed-
COV_Notification if the considered value, e.g. for a range of 0 ... 10 V, changes by ≥ 1 absolute.
This requires an active SubscribeCOV_Service to send the relevant object instance.
You can also set the COV_Increment via the object property "COV_Increment" of the relevant analog
input, analog output or analog value.
p2027 BACnet language selection
German/English - only becomes effective after power off/on
r2029 Fieldbus fault statistics
Displays receive faults on the fieldbus interface
p2040 Fieldbus monitoring time
0 ms ... 1999999 ms, factory setting = 100 ms
The more slaves that are connected in the network, the longer the fieldbus monitoring time must be.
If process data is not transferred within one cycle of the fieldbus monitoring time, then the inverter shuts
down with fault F01910.
p2040 = 0 ⇒ bus monitoring deactivated.
