• For many applications, the inverter is not allowed to auto-run to avoid device damage and ensure
safety due to no person interference at power on. In these applications, when the inverter’s power
is initialized and ready to run, it can not start to run until the terminal run command is given.
1: Level enabled mode.
• For certain applications, when ensured personal safety and device safety it need the inverter
immediately run at power on in order to provide automation and efficiency. In these application, the
inverter will immediately run as soon as the terminal run command is given whether before or after
power on.

For 380V inverter, this braking voltage range is 630-750V.
For 220V inverter, this braking voltage range is 380-450V.
Note: Only in inverter running status the braking is enabled.

Fixed length arrive and stop function (F19.26
F19.34)
This group is used to realize fixed
function. As the right figure:
The inverter inputs the count pulse from
terminal (multi-
function terminal is set as No.
52 function) and
according to the measuring
per revolution (F19.31) and
(F19.30). Then
modify the count length and
obtain the actual length (F19.27) via
ratio (F19.28) and
length checking coefficient
(F19.29) too.
The formula is as follows:
F19.27 = Counted length × F19.28 ÷ F19.29
Counted length = Counted pulse number ÷ F19.31 × F19.30 × π
If F19.27 ≥ F19.26, the inverter will automatically send the stop command.
need clear F19.27 or changed to F19.27 < F19.26. Otherwise the inverter can’t be started.
