• 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.

Fixed length arrive and stop function (F19.26
－
F19.34)
This group is used to realize fixed length stop
function. As the right figure:
The inverter inputs the count pulse from the
terminal (multi-function terminal is set as No.
52 function) and gets the count length
according to the measuring number of pulses
per revolution (F19.31) and shaft diameter
(F19.30). Then modify the count length and
obtain the actual length (F19.27) via length
ratio (F19.28) and length checking coefficient
(F19.29) too.
The formula is as follows:
F19.27 = Counted length × F19.28 ÷ F19.29 ÷ 100
Counted length = Counted pulse number ÷ F19.31 × F19.30 ×
π
If F19.27
≥
F19.26, the inverter will automatically send the stop command. Before running again, it
need clear F19.27 or changed to F19.27 < F19.26. Otherwise the inverter can’t be started.
