Flying Start/Ride-Through [44] - WEG CFW-11 Programming Manual

When the PID regulator is active (P0203 = 1) and in Automatic mode, for the inverter to leave the disable condition, besides
the condition programmed in P0218, it is also necessary that the PID error (the difference between the Setpoint and the
process variable) be higher than the value programmed in P0535. Refer to the
for more details.
P0219 – Zero Speed Time
Adjustable 0 to 999 s
Range:
Properties:
Access groups 01 PARAMETER GROUPS
via HMI:
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 Item 13.1.4 Digital Outputs / Relays [41] on page

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, VVW or Vector), they
will be described in full detail next, for each one of the modes.
P0320 – Flying Start/Ride-Through
Adjustable 0 = Off
Range: 1 = Flying Start
2 = Flying Start / Ride-Through
3 = Ride-Through
Properties: CFG and PM

via HMI:
Description:
The parameter P0320 selects the functions Flying Start and Ride-Through use. More details in the subsequent sections.
