 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 the 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.
• When the motor rotation direction is restricted in Pr.78 Reverse rotation prevention selection, rotation is performed not
in the prohibited direction but in the permitted direction.
Output frequency
• Use Pr.1472 Cleaning reverse rotation frequency and Pr.1474 Cleaning forward rotation frequency to set the running
frequency for cleaning operation, and use Pr.1473 Cleaning reverse rotation operation time and Pr.1475 Cleaning
forward rotation operation time to set the operating time after the cleaning running frequency is reached.
• Use Pr.1477 Cleaning acceleration time and Pr.1478 Cleaning deceleration time to set the acceleration/deceleration
time for cleaning operation.
• The Y215 signal turns ON during cleaning operation. For the Y215 signal, set "215 (positive logic)" or "315 (negative logic)"
in any parameter from Pr.190 to Pr.196 (Output terminal function selection) to assign the function.
