Set the range of setting prohibit frequency in the units of 0.1 Hz.
The range of the setting prohibit frequency is determined as fol-
lows, depending on combinations with No. 50 to No. 52.

When search command is “closed” during baseblock, speed
search is started after Inverter output is shut off for the minimum
baseblock time.
Search commands with set values of 9 and 10 cannot be set at the
same time.
Set value = 9: Speed search starts with the maximum frequency.
