RS-485 Communication Features
7.4.3 BACnet Quick Communication Start
Follow the instructions below to configure the BACnet network for a quick start.
1 Set five multi-function input terminals (IN-65–71 PxDefine) to ‗Interlock 1‘ – ‗Interlock 5‘
respectively, in the correct motor order.
• When auto change mode selection (AP1–55) is set to ‗0 (None)‘ or ‗1 (Aux)‘,
and if 5 motors are operated, including the main motor, the interlock numbers
1,2,3,4,5 refer to the monitors connected to Relay 1,2,3,4,5 (If interlock
numbers 1,2,3,4,5 are connected to Relay 1,2,3,4,5 at the inverter output
terminal).
• If auto change mode selection (AP1-55) is set to ‗2 (Main)‘, and the main and
auxiliary motors are connected to the inverter output terminal Relay 1,2,3,4,
Interlock 1,2,3,4 are the monitors connected to Relay 1,2,3,4. Set COM-04
Int485 Mode.
2 Set the Device Object Instances for COM-21 and 22 and dfine the values. The device
object instances must have unique values.
3 Set COM-01 (Int485 St ID) by entering a value (for BACnet, the Int485 station ID must
be set within a range of 0–127). The station ID value set at COM-01 must be within the
value range defined by the Max Master Property of different Master for MS/TP token
passing.
4 Test the network and make sure the BACnet communication is working properly.
