Parameter
Explanation
p0015 = 110
Macro drive unit
Set communication via BACnet MS/TP
Default setting of the interfaces (Page 16)
p2020
Fieldbus interface baud rate
p0015 = 110 sets p2020 = 6
4: 2400 baud
5: 4800 baud
6: 9600 baud
7: 19200 baud
8: 38400 baud
9: 57600 baud
10: 76800 baud
11: 93750 baud
12: 115200 baud

p2021
Fieldbus interface address
Valid USS addresses: 1 … 127.
The parameter is only active if address 0 is set at the Control Unit address switch.
A change only becomes active after the inverter power supply is switched off and
switched on again.
p2024
Fieldbus interface times
[0] maximum permissible processing time (APDU
timeout)
p2025
Fieldbus SS BACnet settings
[0] = device object instance number
[1] = info maximum number frames
[2] = APDU number of retries
[3] = maximum master address
p2026
Fieldbus interface BACnet COV increment
Change in value at which point the inverter sends and UnConfirmedCOVNotification
or and ConfirmedCOVNotification.
r2029
Fieldbus
interface
error statis-
tics
[0] number of error-free telegrams
[1] number of rejected telegrams
[2] number of framing errors
[3] number of overrun errors
[4] number of parity errors
[5] number of starting character
errors
[6] number of checksum errors
[7] number of length errors
