Setting the Drive Networking Parameters
1.
1. Set parameter H5-01, Serial Node Address, on each drive.
Note: For optimal performance, use consecutive numbers starting from 1. Parameter setting H5-01 must be unique for each drive.
2.
Set parameter P9-25, Highest Node Address, on each drive.
Note: For optimal performance, set to highest H5-01 value. This setting must be the same for all the drives on the network.
3.
Set P1-01 to 3 (MEMOBUS/Modbus Network) on all the drives.
4.
Cycle main power to all networked drives.
Note: The H5-01 setting will not take effect until power is cycled to the drive and may cause communication errors and unexpected
behavior.
Verifying Drive Network Communications
Access monitor U9-02, Network Activity, and verify:
• No drives have a value of 0 <->
• All drives are receiving valid data indicated by a regular change in the monitor value.
• At least one drive has the unit <M>, while the others have the unit <+>.
Network State
Drive is the Master and is
communicating with
another drive.
Drive is a node on the
network and is
communicating with a
Master.
Drive is not able to
communicate to any other
drives.
If a drive displays U9-02 = 0 <->:
