 Cleaning operation by the cleaning signal (X97 signal)
• When X97 signal is assigned to an input terminal, the cleaning operation can be finished when the cleaning signal (X97)
is turned from ON to OFF.
• For the X97 signal input, set "97" in any parameter from Pr.178 to Pr.189 to assign the function.
Pr.1470 setting

Other than 0
NOTE
• When a trigger occurs during the following operations, the cleaning operation is started upon completion of the following
operations.
Automatic restart after instantaneous power failure, online auto tuning at startup
• The following functions are disabled during cleaning operation.
PID control automatic switchover frequency, PID control sleep function, pre-charge fault, determination of pre-charge ending
with parameters, PID gain tuning, switchover to the commercial power supply operation with the automatic switchover
frequency of the inverter (Pr.139), automatic switchover of auxiliary motors of the multi-pump function, output stop function
(Pr.522), restart at every start during cleaning
• When the stall prevention is activated during acceleration of the cleaning function, the operation is shifted to the cleaning
deceleration operation.
• If the number of cleaning times set in Pr.1470 is an even number, the operation is shifted to the normal operation after the
cleaning forward/reverse operation time (Pr.1473/Pr.1475) of the final cleaning operation has elapsed.
• Changing the terminal assignment with Pr.178 to Pr.189 and Pr.190 to Pr.196 may affect other functions. Set parameters
after confirming the function of each terminal.
