10.3.3. BACnet MSTP Parameters
The following parameters are used to configure the drive when connecting to a BACnet MSTP network.
Par. Parameter Name
P1-12 Control Source
P5-01 Drive Address
P5-03 Baudrate
P5-04 Data Format
P5-07 Fieldbus Ramp Control
P5-09 BACnet Device Instance ID Low
P5-10 BACnet Device Instance ID High
P5-1 1 Max Master
10.3.4. BACNet MSTP Commissioning
In order to connect the drive and operate on a BACnet MSTP network, the following procedure should be used.
1. Set P1-14 = 101 to allow access to the extended parameters.
2. On each drive, set an unique Drive Address in parameter P5-01.
3. Set the required baudrate in P5-03.
4. Select the required data format in P5-04.
5. Define a unique BACnet Device Instance ID for each drive using parameters P5-09 and P5-10.
6. Select control from BACnet connection by setting P1-12 = 6.

Set this parameter to 6 to activate BACnet MSTP operation.
This parameter is used to set the drive address on the BACnet network. Each drive on a given
network should have a unique value. By default, all drives are set to MAC ID 1.
This parameter is used to set up communication baudrate. It should be set to match the chosen
baudrate of the BACnet system. Auto baudrate is not supported.
Use this parameter to set RS485 communication data format. Possible settings are as follows:
n-1 : No parity, one stop bit (default setting)
n-2 : No parity, two stop bits
O-1 : Odd parity, one stop bit
E-1 : Even parity, one stop bit
The setting must match the requirement of the BACnet network.
This parameter determines whether the acceleration and deceleration time of the drive is
controlled by the drive internal parameters (P1-03 : Acceleration Time, P1-04 : Deceleration
Time), or controlled directly from the BACnet MSTP network. In most cases, using the drive internal
parameters is the best solution.
P5-09 and P5-10 are used to setup drive device instance ID value.
Instance ID = (P5-10 * 65536) + P5-09. The allowed setting range is Range from 0 ~ 4194304.
Default value is set to 1.
Set BACnet MS/TP max master property, range from 1 ~ 127. Default set to 127.
