6-3 Special functions
(2) When the external signal terminals are used to operate and stop the inverter, and you do not want the motor
to automatically restart after recovery from a power failure, use the above circuit and set F1108=0.
(3) When operating with the hold function, the inverter does not restart after recovery from the following
conditions.
①
Recovery from free run stop with MBS multifunctional input terminal
②
Recovery from alarm stop with the auto alarm recovery function
③ Recovery from a momentary power failure by the ―restart after momentary power failure‖ function
6-3-3 Notes on free run stop terminal (MBS)
The free run stop terminal is provided for systems in which mechanical braking is used to stop the motor. When
setting the motor to the free run status using this terminal, be sure to turn OFF any operation signal.
If the free run stop signal is released with an operation signal on, the inverter restarts according to normal operating
procedure and the function code settings. Therefore, depending on the free run speed of the motor, an unexpected
over current or overvoltage may occur and result in an alarm stop.
For example: if flying start is not set as the starting method and the free run stop signal is released when the motor is
still slowly rotating, the inverter will restart from the starting frequency or after DC braking depending on the
starting method.
