 Cleaning operation by the cleaning signal (X97 signal)
• When the 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 of Pr.178 to Pr.189 to assign the function.

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, electronic bypass
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.
