Remove Freq Level
Remove Freq Lvl
When P9-12 = 0 and the output frequency drops below this level for the time set
in P9-15, the lead drive will request to be removed from the system through the
iQpump MEMOBUS network.
When P9-12 = 2 and the output frequency drops below this level and the delta
feedback (feedback - setpoint) has exceeded the level set in P9-14 for the time
set in P9-15, the lead drive will request to be removed from the system through
the iQpump MEMOBUS network.

High Feedback Quick De-
Stage
High FB De-stage Determines the feedback level to trigger a quick de-stage, set as a percentage of
parameter P1-09. The quick de-stage ignores parameters P9-12 to P9-15 and
only uses an internal 2 second delay.

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.

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
When no messages are received from the master for the time set in

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).
