This feature (skip frequencies) prevents the motor from
operating permanently at speeds where the mechanical
system enters into
resonance,causing high vibration or
noise levels.
The enabling of this function is performed by setting
P306

0.00.

Reference
Output Frequency
The passage through the skip frequency band (2xP306)
uses the programmed acceleration/deceleration ramps.
This function does not work properly if two skip
frequencies overlap.
In applications where the motorcurrent is lower than the
rated inverter current, and where the braking torque is
not enough forthe brakingcondition,please contactWEG
to optimize the settings.

Maximum allowable value for WEG serial protocol is 30
andmaximum allowable value for Modbus-RTU protocol
is 247.
For more details about the Serial communication refer
to the item 8.24 and 8.25.
The serial interface is an optional inverter accessory.
Refer to the items 8.11, 8.12 and 8.16 for detailed
information.
