disconnection will not be detected.
(This function will not be enabled until the output frequency of the inverter must exceed
this frequency after the soft start time and be lower than this frequency after deceleration.)

The set time of F27.23 is calculated when the wire disconnection is identified. According
to the setting of F27.24, the operating frequency in this period is reverse during unwinding and
positive during winding.

F27.25 and F27.26 are not valid until one output terminal is defined as “brake control”
(67# function).
When the output frequency of the inverter drops to the set value of F27.25, the brake control
terminal will be valid and maintained (the brake mode 1 is enabled).
It will be invalid after the set time of F27.26. When the brake control terminal is valid, the
inverter will stop freely.
There is no response to the running command when the brake control terminal is valid.
If F27.26 is set to 0.0, the brake control terminal will remain valid and can be reset by the
brake reset terminal or protection reset terminal.
