0
This parameter is used to set whether to enable the safety protection. If it is set to 1, the AC
drive does not respond to the run command valid upon AC drive power-on (for example, an
LQSXWWHUPLQDOLV21EHIRUHSRZHURQ7KH$&GULYHUHVSRQGVRQO\DIWHUWKHUXQFRPPDQG
is cancelled and becomes valid again.
In addition, the AC drive does not respond to the run command valid upon fault reset of the
AC drive. The run protection can be disabled only after the run command is cancelled.
In this way, the motor can be protected from responding to run commands upon power-on or
fault reset in unexpected conditions.

These two parameters are respectively used to set the detection value of output frequency
and hysteresis value upon cancellation of the output. The value of F8-20 is a percentage of
the hysteresis frequency to the frequency detection value (F8-19).
