Mitsubishi Electric FR-F820-00077 Instruction Manual page 521

Parameters
● 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.
Fig. 5-156:
● 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.

Tab. 5-164: Cleaning operation and trigger condition
The ON state at power-ON or inverter reset is not regarded as a trigger.
Use Pr. 150 and Pr. 151 to set the detection level. (Refer to page 5-244.)
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 page 5-353.)

Turning ON of the start command is defined
Trigger enabled
as a trigger.
Turning ON of Y12 signal is defined as a
Trigger enabled
trigger.
Turning ON of FUP, FDN, FUP2, or FDN2 signal
Trigger enabled
is defined as a trigger.

Trigger enabled
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.
