Pr-55 :
Stand-by Pump Waiting Time on Multi-Drive Control Mode
This is to give some delay to stand-by pump. If the stand-by pump starts operation before the main
drive outputs maximum frequency then the pressure may increase suddenly.
Pr-61 :
PID Type Setup on Multi-Drive Control Mode
Centralized control is a method that all of drivers participating into operation are allocated with
target value for the output frequency by one PID controller of Master.
Pr-70 :
High Pressure Alarm Level
It sets standard pressure value to issue the high pressure alarm.
When setting the setup pressure, it is automatically set to setup pr 2bar.
Pr-71 :
Low Pressure Alarm Level
It sets standard pressure value to issue the low pressure alarm.
Pr-72 :
High Pressure Alarm Time
It sets maintaining time of high pressure alarm level to issue the high pressure alarm. That is, if
the current pressure increases above the high pressure alarm level (Pr-70) and maintains its
state for a specified time, a high pressure alarm is displayed and operation stops.

Drive
Pr-64 :
Output Ratio on Starting Increase of All PID(Preparing)
It is an output ratio to start the next drive by applying it centralized control method for multiple pump
operation. That is, if the output ratio of drive in operation is higher than a specified value, the next
drive to be linked starts to be operated.
