Highest Node Address
Highest Node Address
Defines the highest possible node address in the MEMOBUS /
Modbus Network. To yield optimal network performance, it is
recommended to set the serial communication address H5-01 starting
from 01h and then consecutively up to the last drive and then setting
this parameter to that H5-01 address.

Master Time-out
Master Time-out Sets the minimum amount of time that he slave drives will wait for a
message from the master before performing the action set in P9-27. 3.0 ~

4.0 s Programming
P9-27 089A
Network Recovery
Network Recovery
When no messages are received from the master for the time set in
P9-26, the slave drive will act according to this setting:
0: Automatic - drive will attempt to assume master functionality.
1: Slave / Resume - drive will continue running when the master is
lost and will wait for a master to come on-line.
2: Slave / Stop - drive will stop running when the master is lost and
will wait for a master to come on-line.
3: Fault MSL - fault the drive with an MSL (Master Lost).
Note: The drive will keep running in its current operation state which
could cause an undesirable condition.

No message received form the master within the time
specified in P9-26 when Network Recovery is set to
Fault MSL (P9-27 = 3).
Increase P9-26 to account for network latency.
Verify that there is a drive on the network with
parameters set as P1-01 = 3 and P9-27 = 0.
Check network connections and verify H5-01 and
P9-25 for all drives on the network.

Network Activity
Network Activity
Shows network traffic. A fluctuating number from 0 to 1000 denotes activity, while a relatively constant 0
denotes no activity.
Unit changes based on network status:
<->: Drive can not communicate to other drives
<+>: Drive is a Node on a network
: Drive is a Master on an iQpump Network
(*n1) Displayed units are determined by parameter P6-02.
