This is a function to remove stains or foreign matter on the impellers or fans of pumps by setting a forward/reverse rotation
sequence.
Outline of the cleaning operation
• Setting a number in Pr.1470 Number of cleaning times setting enables the cleaning function.
• The cleaning operation is started when the trigger set in Pr.1471 or Pr.1479 occurs, or when X98 signal turns ON. When
the cleaning is started initially, the operation in the opposite direction to the start command is performed.
• When the number of times of cleaning operation is an odd number, the operation in the opposite direction to the start
command is performed. When the number of cleaning times is an even number, the operation in the start command
direction is performed.
