Parameter Description
 Setting the time to monitor the process data received. If no process data is
received within this time, an appropriate message is output
 Factory setting: 100 ms
 The factory setting for communication with BACnet is possibly too low and must be
increased. Adapt the value to the requirements and properties of your particular
plant or system.
 The setting 0 ms deactivates the monitoring.

The configuration workload can be reduced by leaving out values which are not
required. In this case, the appropriate parameters must be set manually.
Example: If you are not using BV93, set p0854 to 1.

Parameter Value Description
p0840 r2090.0 Wire ON/OFF1 to control word 1 bit 0
p0852 r2090.3 Wire the signal for "Enable operation" to control word 1 bit 3
p0971 1 Permanently save the settings in the drive
p1070 r2050.1 Connect the signal for the main setpoint to the communication
interface
p2030 8 Communication protocol for P1
With this setting the drive sets parameters p2020 and p2021 as
follows:
 p2020 = 5: Baud rate 4800 bit/s, alternative setting option for P1:
p2020 = 6 (9600 bits/s)
 p2021 = 1 … 99: Slave address (factory setting = 99).
p2051.0 r52.0 Send status word via the communication interface
p2051.1 r63.0 Send actual speed value via the communication interface
