• 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.
• 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 during cleaning operation.
• Y215 signal turns ON during cleaning operation. For the Y215 signal, assign the function by setting "215 (positive logic)"
or "315 (negative logic)" in any of Pr.190 to Pr.196 (Output terminal function selection).
 Cleaning trigger selection (Pr.1471, Pr.1479, X98 signal)
• Use Pr.1471 Cleaning trigger selection the trigger to start cleaning operation. As set in Pr.1471, cleaning operation is
started when any of the applicable trigger conditions is satisfied.

*1 The ON state at power-ON or inverter reset is not regarded as a trigger.
*2 Use Pr.150 and Pr.151 to set the detection level. (Refer to
*3 Use Pr.131, Pr.132, Pr.1143, and Pr.1144 to set the detection level. When the frequency reflection is not provided for the PID setting, or when
the function is disabled, a trigger does not occur. (Refer to
*4 Set the load characteristics fault detection function. When the function is disabled, a trigger does not occur. (Refer to
*5 The output signal can be used as a trigger if the signal is not assigned to a terminal.
*6 When the automatic restart after instantaneous power failure is set for every start, or when the online auto tuning is enabled, cleaning is started
upon completion of the set operations.
*7 While the self power management is enabled, the start trigger is disabled.

Turning ON of Y12 signal is defined as a trigger.
Trigger enabled Turning ON of FUP, FDN, FUP2, or FDN2 signal is
defined as a trigger.
Trigger enabled Turning ON of LUP or LDN signal is defined as a trigger.

Turning ON of X98 signal is defined as a trigger. (This
trigger is always enabled by assigning X98 signal to an
input terminal.)
When Pr.1479  "0", the trigger is enabled.
