Cleaning Operation By The Cleaning Signal (X97 Signal) - Mitsubishi Electric FR-F800 Instruction Manual

• Turning ON of X98 signal can be used as a trigger to start the cleaning operation. For the X98 signal input, set "98" in any
of Pr.178 to Pr.189 to assign the function.
• When using the cleaning function for the purpose of periodic maintenance in such applications that require continuous
pump operation for a long time, use a time trigger. The time trigger is enabled by setting a time period before starting the
cleaning operation in Pr.1479 Cleaning time trigger. The timer starts when the timer starting condition is satisfied, and the
cleaning operation is performed at a time interval set in Pr.1479.
• Starting conditions of the timer for a time trigger
- When the start command turns ON
- When the cleaning ends

Cleaning operation by the cleaning signal (X97 signal)
• When 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.
