During a constant speed operation, the operating frequency is saved
automatically in the following conditions: the operation command (Fx or
Rx) is off, a fault trip occurs, or the power is off.
When the operation command is turned on again, or when the inverter
regains the power source or resumes to a normal operation from a fault
trip, it resumes operation at the saved frequency. To delete the saved
frequency, use the multi-function terminal block. Set one of the multi-
function terminals to 20 (U/D Clear) and apply signals to it during constant
speed operation. The saved frequency and the up-down operation
configuration will be deleted.
