Setting the parameters – Example for ACS580
Standard control program
If the communication adapter module is used to chain a control
panel or a PC to several drives, set the parameters of group 49
Panel port communication for each drive before you connect the
drives to the bus.
1. Power up the drive.
2. Define the node ID of the drive (
49.01 Node ID number
).
All devices connected to the bus must have a unique node ID.
It is advisable to reserve ID 1 for spare/replacement drives
because they have ID 1 as the default factory setting. Start
numbering from ID 2.
3. Set the baud rate of the drive (
49.03 Baud rate
).
The baud rate has to be the same for all nodes on the bus.
4. Select a suitable value for parameter
49.05 Communication
loss action value
.
This parameter defines the operation of the drive when the
control panel communication breaks.

•
Last speed (2):
