DANGER!
When in the Sleep mode, the motor can spin at any time considering the process conditions. If you
wish to handle the motor or execute any kind of maintenance, power down the inverter.
P0217 – Sleep Frequency
Adjustable
Range:
0.0 to 500.0 Hz Factory
Setting:
0.0 Hz
Properties:
Access Groups
via HMI:
Description:
Parameter P0217 defines a value for the frequency reference, seeing that below this value the inverter may go
into the Sleep mode depending also on P0218 and P0535.
The Sleep mode disables the inverter at moments in which the frequency reference is below P0217. That will
happen after the time interval set in P0218.
If the frequency reference goes above P0217 again, the inverter will exit the Sleep mode automatically. However,
if the inverter is in the PID mode in automatic, besides the previous condition, if the error in the PID is higher than
the value programmed in P0535, the inverter will also exit the Sleep mode.
P0218 – Sleep Time
Adjustable
Range:
0 to 999 s Factory
Setting:
0 s
Properties:
Access Groups
via HMI:
Description:
The parameter P0218 establishes the time interval in which the Sleep mode conditions by P0217 and P0535
must remain stable. That prevents that momentary disturbances and oscillations incorrectly activate the Sleep
state.
11.4 FLYING START / RIDE-THROUGH
The Flying Start function allows driving a motor that is in free spinning, accelerating it from the rotation in which
it is. The Ride-Through function allows recovering the inverter, with no locking by undervoltage, when there is an
instant drop in the power supply.
Both functions have as a premise the special case in which the motor is spinning in the same direction and at
a speed close to the speed reference, and, thus, immediately applying to the output the speed reference and
increasing the output voltage in ramp, the slip and the starting torque are minimized.
