Description:
It defines whether or not the Zero Speed Disable function will be timed.
If P0219=0, the function works without timing.
If P0219>0, the function will be configured with timing, and the counting of the time adjusted in this parameter will
be initiated after the Speed Reference and the Actual Motor Speed become lower than the value adjusted in P0291.
When the counting reaches the time defined in P0219, the inverter will be disabled. If during the time counting any
of the conditions that cause the zero speed disable ceases being fulfilled, then the time counting will be reset and
the inverter continues enabled.
P0291 – Zero Speed Zone
Refer to the section 13.1.4 for more details.

12.7 FLYING START/RIDE-THROUGH [44]

The FLYING START function allows starting a motor that is spinning freely, accelerating it from the speed it is
found.
The other function, RIDE-THROUGH, allows the recovery of the inverter, without being disabled by undervoltage,
when a failure in the voltage supply occurs.
Since these functions work in different manners depending on the used control mode (V/f or Vector), they will
be described in full detail next, for each one of the modes.
