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.
No. 50 to No. 52 – No. 53 ≤ the range of the setting prohibit fre-
quency ≤ No. 50 to No. 52 + No. 53

Note 1. Constant-speed operation is prohibited in the setting prohibit
frequency range. Output frequency does not jump during
acceleration or deceleration, which is performed smoothly.,
2. Set as follows; No. 50 ≥ No. 51 ≥ No. 52
2-8-25 Speed Search Function
Item name Constant to be set Factory preset
Multifunction contact input function No. 32, 33 ---
Speed search deactivation current level No. 54 150%
Minimum baseblock time No. 55 0.5 s
V/f during speed search No. 56 100%
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.
Search Command (Set
Value = 9, 10) (No. 32
or No. 33)
