PID output hold (Pr.1361 and Pr.1362)
• The manipulated amount (PID output) can be fixed when the fluctuation of the deviation is small. This function
eliminates unnecessary acceleration/deceleration, which is effective to reduce the power consumption.
• When the deviation falls within the Pr.1362 PID output hold range and the elapsed time exceeds the Pr.1361
Detection time for PID output hold, the manipulated amount (PID output) is fixed at the output frequency at that
time.
• Even if the deviation falls out of the PID output hold range, the manipulated amount (PID output) is kept during the
detection time for PID output hold.
NOTE
• While the PID output is held, calculation is not performed for the P term, I term, and D term. For the P and I terms,
the values at the start of the holding period are kept. The D term is set to "0".
• When the control switches between the first PID control and second PID control, the PID output holding state is
canceled.
• The PID output holding function is disabled in the following cases:
When Pr.1362="9999", while the PID setting is not applied to the frequency, during the sleep function, at switching
to the auxiliary motor in the multi-pump function, during PID gain tuning, and during the sleep boost.

Stirring function during the PID sleep (Pr.1364 and Pr.1365)
• This function starts the pump periodically to prevent clogging of the pump while the PID output suspension
function (sleep function) is activated.
• When the sleep function is activated and the elapsed time exceeds the Pr.1365 Stirring interval time, the pump
is operated at the stirring frequency (Pr.232 or Pr.233). The pump decelerates to stop when the elapsed time
exceeds the Pr.1364 Stirring time during sleep. The interval time count for the second time onward starts after
the previous deceleration stop is completed.
• The rotation direction depends on the Pr.232 and Pr.233 settings.
• The stirring signal (STIR) turns ON during the stirring operation. For the STIR signal, set "218 (positive logic)" or
"318 (negative logic)" in any of Pr.190 to Pr.196 (output terminal function selection) to assign the function.
• When Pr.579 Motor connection function selection="1 or 3" (multi-pump function), the starting order of the
motors is changed when the sleep function is activated. The stirring operation during the sleep is applied to the
motor to be started first next time. For example, when the previous starting order was M1 M2 M3 M4, and
the next starting order of motors is M2 M3 M4 M1, stirring operation during the sleep will be applied to the
M2 motor.
• When the auxiliary motor starting condition is satisfied by the stirring operation during the sleep while the multi-
pump function is used, the stirring operation continues. The auxiliary motor does not start.
NOTE
• When the control switches between the first PID control and second PID control during the sleep function, the
interval time and the stirring time timer are carried over.
• When the sleep function cancellation condition is satisfied, the sleep function is cancelled, and the stirring function
during the sleep is also cancelled.
• Changing the terminal assignment using Pr.190 to Pr.196 (output terminal function selection) may affect the
other functions. Set parameters after confirming the function of each terminal.

PID priming pump function (Pr.1363)
• This function starts the priming pump first before starting the main pump so that the main pump does not intake air
at start.
• When the start command is turned ON after setting Pr.1363 PID Priming time"9999", the priming pump
operation signal (Y217) turns ON to start the priming pump. When the elapsed time exceeds the Pr.1363 setting,
the main pump starts.
• The priming pump continues operation during operation of the main pump. When the STF signal is turned OFF to
stop the main pump, the priming pump also stops.
• For the Y217 signal, set "217 (positive logic)" or "317 (negative logic)" in any of Pr.190 to Pr.196 (output terminal
function selection) to assign the function.
NOTE
• The priming operation is performed at every startup.
• When the operation is restarted after inverter reset by a protective function activation, the priming operation is
performed.
• When the control switches between the first PID control and second PID control during the priming time, the
priming time is carried over.
• The PID priming pump function is enabled when the PID setting is applied to the frequency.
• Even when the inverter emergency stop operation (output shutoff by the MRS signal, etc.) is performed, the PID
priming pump function operation continues while the power is supplied to the control circuit. For the emergency
stop operation, configure another circuit to stop the priming pump.
• Changing the terminal assignment using Pr.190 to Pr.196 (output terminal function selection) may affect the
other functions. Set parameters after confirming the function of each terminal.

PID auxiliary pressure pump function (Pr.1374 and Pr.1375)
• This function enables signal output to activate an auxiliary pressure pump when the pump flow rate is low in the
system which constantly requires a high pressure.
• When the deviation exceeds the auxiliary pressure pump operation starting level (Pr.1374 Auxiliary pressure
pump operation starting level - 1000%) after the PID output suspension function (sleep function) is activated,
the auxiliary pressure pump starts and the auxiliary pressure pump operation signal (Y226) turns ON.
• When the deviation falls below the auxiliary pressure pump operation stopping level (Pr.1375 Auxiliary pressure
pump operation stopping level - 1000%) during the auxiliary pressure pump operation, the auxiliary pressure
pump stops.
• For the Y226 signal, set "226 (positive logic)" or "326 (negative logic)" in any of Pr.190 to Pr.196 (output terminal
function selection) to assign the function.
NOTE
• The recommended settings of Pr.577 (Pr.1149), Pr.1374, and Pr.1375 are as follows.
Pr.577 (Pr.1149) > Pr.1374 > Pr.1375
• Even when the inverter emergency stop operation (output shutoff by the MRS signal, etc.) is performed, the PID
auxiliary pressure pump function operation continues while the power is supplied to the control circuit. For the
emergency stop operation, configure another circuit to stop the auxiliary pressure pump.
• Changing the terminal assignment using Pr.190 to Pr.196 (output terminal function selection) may affect the
other functions. Set parameters after confirming the function of each terminal.

PID overpressure control (Pr.1370 and Pr.1376)
• When the main valve is suddenly closed in the multi-pump function system, a sudden increase of the pipe
pressure may occur, and the pipes may be broken. To prevent fracture of the pipes, all auxiliary motors are
stopped when the feedback value exceeds the predetermined level.
• When the PID measured value reaches or exceeds the Pr.1376 Auxiliary motor stopping level and the elapsed
time exceeds the Pr.1370 Detection time for PID limiting operation while the multi-pump function is activated,
all operating auxiliary motors are disconnected and allowed to coast to a stop regardless of the Pr.579 Motor
connection function selection setting. The motor driven by the inverter continues its operation. (For the details
of Pr.579, refer to page 406 of the Instruction Manual (Detailed).)
• When the auxiliary motor is once stopped, the motor operation does not start while the PID measured value is the
Pr.1376 setting or more even when the auxiliary motor starting condition is satisfied.
NOTE
• The PID overpressure control function can be used when PID control is performed (reverse action only) by the set
point or measured value input using the multi-pump function.
• Either the first or the second PID measured value is used according to the PID control selection. When the control
switches between the first PID control and second PID control, the measured value to be used is also switched to
continue the control operation.
PID sleep boost (Pr.1366 to Pr.1368)
• The pump pressure can be increased before the PID output suspension function (sleep function) is activated. This
function is useful to prevent frequent repetition of starting and stopping of the pump, and to keep the sleep state
for a long period of time.
• When the normal condition to activate the sleep function is satisfied (the output frequency is less than Pr.576
setting for the time set in Pr.575 or longer), the PID set point automatically increases by the amount set in Pr.1366
Sleep boost level.
• When the measured value reaches to the set point during Pr.1367 Sleep boost waiting time, the sleep function
is activated. Then, the set point returns to its original value from the sleep boost set point.
• When the measured value does not reach to the sleep boost set point after the time set in Pr.1367 passes, PID
control continues without activating the sleep function.
• When the deviation remains at the Pr.577 setting or higher for the time set in Pr.1368 Output interruption cancel
time, the inverter output restarts.

Check valve deceleration function (Pr.111 and Pr.1369)
• When the pump is stopped, slow deceleration can be applied to the predetermined section to prevent the water
hammer sound caused by closing the valve.
• The Pr.111 Check valve deceleration time setting is applied to the section between Pr.2 Minimum frequency
and Pr.1369 Check valve closing completion frequency.
NOTE
• The check valve deceleration function is enabled when the PID setting is applied to the frequency.
• When the Pr.1369 setting is higher than the Pr.2 setting, the normal deceleration time (Pr.8 or Pr.45) setting is
applied.
PID upper/lower limit pre-warning (Pr.1370 to Pr.1373)
• The set point can be changed to prevent increase of the measured value before PID upper limit (FUP) or PID
lower limit (FDN) is detected.
• When the measured value reaches and remains at the pre-warning level set in Pr.1371 PID upper/lower limit
pre-warning level range for the time set in Pr.1370 Detection time for PID limiting operation, the PID upper/
lower limit pre-warning signal (Y219) or the second PID upper/lower limit pre-warning signal (Y220) is output.
Also, the set point is changed by the amount set in Pr.1372 PID measured value control set point change
amount.
• Set the rate (%/s) for changing the set point by the Pr.1372 setting value in Pr.1373 PID measured value control
set point change rate. When the measured value falls within the normal range, the set point returns to its original
value.
• For the Y219 and Y220 signals, assign the functions to output terminals using the Pr.190 to Pr.196 (output
terminal function selection).

NOTE
• When Pr.554="5, 7, 15, or 17" and a deceleration stop is performed by the FUP/FDN signal detection, the set point
changed by the Pr.1372 setting value remains effective.
• The set point change by the PID upper/lower limit pre-warning function is enabled when the PID setting is applied
to the frequency.
• When the control switches between the first PID control and second PID control while the set point is changed by
the Pr.1372 setting value or while the Y219 (Y220) signal is output, the set point returns to its original value.
PID dry run monitoring function (Pr.1370)
• This function can prevent operation without water in the pipes by monitoring the flow rate (measured value) inside
the pipes. When the flow rate decreases while the FU signal is ON, an output signal is sent for notification.
• The dry run signal (DRY) is output during PID control when the measured value is lower than the lower limit
(Pr.132 or Pr.1144) and the output frequency is higher than the setting in Pr.42 Output frequency detection or
Pr.43 Output frequency detection for reverse rotation (FU signal ON) for the time set in Pr.1370 Detection
time for PID limiting operation.
• For the DRY signal, set "228 (positive logic)" or "328 (negative logic)" in any of Pr.190 to Pr.196 (output terminal
function selection) to assign the function.
• The PID dry run monitoring function is enabled for the reverse action.
NOTE
• The PID dry run monitoring function is enabled when the PID setting is applied to the frequency.

PID input pressure control (Pr.1370, Pr.1373, and Pr.1377 to
Pr.1381)
• This function controls the pump inlet pressure to prevent water shortage that may cause air intake or cavitation on
the pump.
• To enable the PID input pressure control function, set the terminal for the pressure input in Pr.1377 PID input
pressure selection.
• When the input pressure measured at the inlet remains lower than the Pr.1378 PID input pressure warning
level for the time set in Pr.1370 Detection time for PID limiting operation, the PID input pressure warning
signal (Y229) is output. Also, the set point is changed by the amount set in Pr.1380 PID input pressure warning
set point change amount.
• Set the rate (%/s) for changing the set point by the Pr.1380 setting value in Pr.1373 PID measured value control
set point change rate. When the input pressure falls within the normal range, the set point returns to its original
value.
• When the input pressure measured at the inlet remains lower than the Pr.1379 PID input pressure fault level for
the time set in Pr.1370 Detection time for PID limiting operation, the operation for the abnormal input pressure
starts and the PID input pressure fault signal (Y230) is output.
• Select the operation for the abnormal input pressure in Pr.1381.
• For the Y229 and Y230 signals, assign the functions to output terminals using the Pr.190 to Pr.196 (output
terminal function selection).
• To monitor the input pressure, set "69" in the monitor selection parameters. (0.1% increments)

• When the control switches between the first PID control and second PID control while the set point is changed by
the Pr.1380 setting value or while the Y229/Y230 signal is output, the set point returns to its original value or the
signal turns OFF, and the detection restarts.
• When the PID input pressure control function and the PID upper/lower limit pre-warning function are used
simultaneously, each function may change the set point. When the set point change is attempted by both functions,
the change by the PID input pressure control function has priority.
• When the PID input pressure control function and the PID sleep boost function are used simultaneously, each
function may change the set point. When the set point change is attempted by both functions, the change by the
PID input pressure control function has priority. (The sleep state is established without applying the set point
change by the PID sleep boost function.)
