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 the iQpump1000 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 <+>.

If a drive displays U9-02 = 0 <->:
• Check physical connections.
• Verify the H5-
oo serial communication settings.
• Confirm the P9-25 and P9-27 settings on all the drives. P9-25 should be set to the highest H5-01 address and at least one
drive should have P9-27 set to 0.
• Cycle main power.
Multiplexing Principle
Always observed by system:
• New drives start as Lead and run in PI mode.
• Only the Lead drive can request staging and de-staging.
• Staging will start a new Lead drive and make the old Lead drive into a Lag drive.
