Yaskawa iQpump1000 AC Drive Quick Start - Manual (Page 223)

The restart counter is incremented at each restart attempt, regardless of whether the attempt was successful. When the counter
reaches the number set to L5-01, the operation stops and the fault must be manually cleared and reset.
The number of fault restarts is reset to zero when:
• The drive operates normally for 10 minutes following a fault restart.
• A fault is cleared manually after protective functions are triggered.
• The power supply is cycled.
No. Name Setting Range Default
L5-01 Number of Auto Restart Attempts 0 to 10 Times 5 Times
n L5-04: Fault Reset Interval Time
Determines the amount of time to wait between restart attempts when parameter L5-05 is set to 1.
No. Name Setting Range Default
L5-04 Fault Reset Interval Time 0.5 to 600.0 s 10.0 s
n o1-08: Third Line User Monitor Selection
Selects the monitor that is shown in the third line. Effective only when o1-06 is set to 1.
Enter the last three digits of the monitor parameter number to be displayed: Uo-oo. For example, set “403” to display
monitor parameter U4-03.
No. Name Setting Range Default
o1-08 Second Line User Monitor Selection 101 to 799 103
n P1-01: Pump Mode
Selects the base operation mode of the drive controller.
No. Parameter Name Setting Range Default
P1-01 Pump Mode 0, 1, 3 0
Setting 0: Drive only
Designed for single pump stand-alone applications
Setting 1: Contactor lag
Contactor Lag systems multiplex a main pump with up to 5 lag pumps. The drive will stage and de-stage the lag pumps based
on system demand by using its digital output contacts to control the lag pump motor starters
Setting 3: MEMOBUS network
Up to eight drives can be networked together to provide for system redundancy and precise control.
When P6-01 > 0, the Flow Rate can come from another drive on the MEMOBUS Network.
Setting P9-40 to 0 (Analog) will read the Flow Meter from the analog terminal (H3-oo = 22) or from the pulse input (H6-01
= 5), while setting P9-40 to 3 (Network) will read the Flow Meter information from the network. When there is no such drive
on the network, a “Net Flow Meter Lost, Chk Source” alarm is triggered for drives with P9-40 set to 3 (Network) and P6-01
> 0.
Staging is disabled when and the drive PI output is influenced by the Water Level / Suction Pressure Control.
The functions listed below will behave slightly different when P1-01 is set to 3:
• Start Level: Active on the first pump in the network. Drives in the process of alternation will not undergo this process.
• Sleep: Active when the drive is the only drive running on the network.
• Over-cycle Protection: Active when the drive is the only drive running on the network.
• Pre-charge: Active only on the first drive to run in the network.
• Low City Pressure: Active on any drive in the network. An alarm condition will cause other drives in the network to stop
running and show a “Net Pump Err” message.
• Utility Delay: When this function is active, the drive is unavailable to the iQpump MEMOBUS Network and will force the
Home Screen text to show “Pump Off Network”.
• Remote Drive Disable: When this function is active, the drive is unavailable to the iQpump MEMOBUS Network and will
force the Home Screen text to show “Pump Off Network”.
