Yaskawa iQpump Micro Quick Start - Manual (Page 100)

No. Name Description
P9-09 Add Frequency Level
When P9-08 is set to 0, this parameter sets
the level above which the output frequency
needs to rise for the time set in P9-11 before
the lead drive will send a request for a new
lead drive via the iQPump MEMOBUS
network.
When P9-08 is set to 2 and the delta
feedback (setpoint minus feedback) has
exceeded the level set in P9-10 for the time
set in P9-11, this parameter sets the level
above which the output frequency needs to
rise before the lead drive will send a request
for a new lead drive via the iQPump
MEMOBUS network.
P9-10 Add Delta Level
When P9-08 is set to 1, this parameter sets
the level above which the delta feedback
(setpoint minus feedback) must rise for the
time set in P9-11 before the lead drive will
send a request for a new lead drive via the
iQPump MEMOBUS network.
When P9-08 is set to 2 and the output
frequency has exceeded the level set in
P9-09 for the time set in P9-11, this
parameter sets the level above which the
delta feedback (setpoint minus feedback)
needs to rise before the lead drive will send
a request for a new lead drive via the
iQPump MEMOBUS network.
P9-11 Add Delay Time
Sets the delay time before a new lead drive
is added to the system.
P9-12 Remove Pump Mode
0: Output frequency
1: Feedback
2: Feedback + Fout
P9-13
Remove Frequency
Level
When P9-12 is set to 0, this parameter sets
the level below which the output frequency
must fall for the time set in P9-15 before the
lead drive will send a request to be removed
from the system via the iQPump
MEMOBUS network.
When P9-12 is set to 2 and the delta
feedback (feedback minus setpoint) has
exceeded the level set in P9-14 for the time
set in P9-15, this parameter sets the level
below which the output frequency must fall
before the lead drive will request to be
removed from the system via the iQPump
MEMOBUS network.
P9-14 Remove Delta Level
When P9-12 is set to 1, this parameter sets
the level above which the delta feedback
(feedback minus setpoint) must rise for the
time set in P9-15 before the lead drive will
request to be removed from the system via
the iQPump MEMOBUS network.
When P9-12 is set to 2 and the output
frequency has exceeded the level set in
P9-13 for the time set in P9-15, this
parameter sets the level above which the
delta feedback (feedback minus setpoint)
frequency must rise before the lead drive
will request to be removed from the system
via the iQPump MEMOBUS network.
P9-15 Remove Delay Time
Sets the delay time before the lead drive is
removed from the system.
P9-16 Stabilization Time
Sets the time used to stabilize the system
when a pump is staged or de-staged.
Lead/lag control and pump protection are
suspended during this time.
P9-17 Setpoint Modifier
Sets the value by which the system setpoint
is incremented depending on the number of
pumps that are running.
Pump 1: Setpoint
Pump 2: Setpoint + ((X-1) (P9-17))
No. Name Description
P9-18
High Feedback Quick
De-Stage
Sets the feedback level that will trigger a
quick de-stage. Set as a percentage of the
P1-11 value.
The quick de-stage ignores parameters
P9-12 to P9-15 and uses an internal 2
second delay.
Setting this parameter to 0.0 disables the
feature.
P9-19 Alternation Unit
Sets the units used in P9-03.
0: Hours (H)
1: Minutes (min)
P9-20 Allow Network Run
0: Always
1: First/alternation
2: First only
3: Alternation only
P9-21 Run Priority
Sets the lead drive selection priority
overriding the P9-01 selection. Lower value
= Higher priority.
If multiple drives have the lowest P9-21
value, then P9-01 determines which drive
becomes the lead.
P9-22 System Fault Retry
Sets the number of times that the iQPump
MEMOBUS network will allow automatic
restarts of system faults.
The drive uses L5-04, Fault Reset Interval
Time, to determine when to attempt a
system fault restart.
Set this parameter to the same value for all
drives on the network.
P9-23
Maximum Number of
Running Pumps
Sets the maximum number of pumps that
can run on the system.
P9-24 Lead Swap at Sleep
Sets the length of time for which the lead
drive will be in Sleep Mode before this drive
will request a swap when there is another
drive available with a lower P9-21 setting.
Setting this parameter to 0 will disable the
function.
P9-25 Highest Node Address
Sets the highest possible node address in the
MEMOBUS network.
For optimal network performance, set the
serial communication address H5-01
beginning with 01h consecutively up to the
last drive and then set this parameter to that
H5-01 address.
P9-26 Master Time-out
Sets the minimum amount of time that the
slave drives will wait for a message from
the master before performing the action set
in P9-27.
P9-27 Network Recovery
0: Automatic. The drive will attempt to
assume master functionality.
1: Slave/Resume. The drive will continue
running when the master is lost and will
wait for a master to come online.
2: Slave/Stop. The drive will stop running
when the master is lost and will wait for a
master to come online.
3: Fault MSL. Fault the drive with an MSL
(Master Lost).
P9-28
NETSCAN Alarm
Time
Sets the amount of time that the slave drives
will wait for a message from the master
before displaying a NETSCAN alarm.
P9-29 Net Start Delay
Sets the amount of time that the network
will wait before selecting and starting the
lead drive after the first drive on the network
has been put on AUTO Mode.
P9-30
Lag Drive Speed
Follower Gain
Sets the gain to be applied to the speed of
the current lead drive when P9-05 is set to
3. The bias to be applied is set in P9-31.
P9-31
Lag Drive Speed
Follower Bias
Sets the bias to be applied to the speed of
the current lead drive when P9-05 is set to
3. The gain to be applied is set in P9-30.
