Explanation of Function
Seite 105 / 180
Free-run stop (FRS)
By operating the free-run stop (FRS) function, the inverter output is cut off.
The motor will free wheel under its own momentum.
This function is used when the motor is to be stopped by the use of a
brake, like an electromagnetic brake.
If you stop the motor with a machine brake while the inverter is still
Outputting to the motor an over-current trip may occur.
Assign 11(FRS) to an intelligent input terminal.
This free-run stop function will operate when the FRS terminal is ON.
If you turn FRS terminal OFF the inverter will restart after the retry wait time b003 passes.
However when the operation command selection A002 is set to control terminal (01), the inverter restarts
during free-running.
This function will only operate when the FW terminal is ON.
On restart it is possible to select 0Hz start or matching frequency start as output methods with the free-run
stop selection b088. (Example 1, 2)
When you set the frequency setting to match (b007) and the frequency detected is under this setting when
the free-run stop is released, the inverter is restarted from 0Hz.
The setting of this function is valid for selection b091 on stopping and reset (RS) action.
