Sets the Lead Drive selection priority overriding the P9-01 selection. If
multiple drives have the lowest P9-21 value, then P9-01 determines which
drive becomes the Lead.

System Fault Retry
System Flt Retry

Determines the number of times the iQpump Memobus Network will allow
automatic restarts of system faults. The drive uses parameter
L5-03 in determining when to attempt a system fault restart.
For proper operation, this parameter should be set the same for all network
drives.

Lead Swap @ Sleep
Lead Swap @ Sleep

When the Lead DRive has been in Sleep for this amount of time and there
is another drive available with a lower P9-21, then this drive will request
for a swap.

Highest Node Address
Highest Node Adr

Defines the highest possible node address in the Memobus 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.

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).
