Reverse frequency Prohibition
(supported by 3720 and above
versions)
0
Invalid
1
Valid
When the motor is not allowed to run in the reverse direction, the parameter should be set to 1.
If P0-21=0 (negative frequency prohibition is invalid), the operation frequency of the communication given
frequency converter is negative or the external given reverse operation command, and the frequency converter
operates in reverse.
If P0-21=1 (negative frequency prohibition is effective), the operation frequency of the communication given
frequency converter is negative or the external given reverse operation command, and the frequency converter
operates at 0Hz.
The function of input terminal 49 "reverse frequency static" is the same as that of P0-21.
For applications where motor reverse rotation is not allowed, please don’t use parameter P0-21 to change the
steering, because the parameter setting will be reset after restoring factory settings.

Setting frequency
This parameter is only valid when the frequency source is digital setting.
This parameter is used to confirm the mode to modify the setting frequency when keyboard ▲, ▼ or terminal
UP/DOWN acted, which means the target frequency is increased or decreased based on the operating frequency
or the set frequency.
The difference between the two settings is obvious when the frequency converter is in the process of
acceleration and deceleration, that is, if the operating frequency of the frequency converter is different from the
set frequency, the different selection of this parameter is very different.
