309 Cut-Off Freq Default: 0.0 Hz
Range: 0.0 to 5.0 Hz
Level 2
This parameter sets the point where the drive no longer attempts to spin the motor. The range of this
parameter is 0.0-5.0 Hz. When the parameter is configured to a value of 0.0 Hz, the drive will operate with
no Cut-off Frequency. If the function is enabled, the drive will be able to ramp up through the cut-off
frequency range, as in normal operation. If the speed command falls below the cut-off frequency, the drive
stops “gating” the outputs and coasts down to zero speed. The keypad display will indicate Zero Speed, and
the Forward or Reverse LED will be lit depending on the command. When the reference returns to a value
greater than the cut-off frequency, the drive will ramp from 0.0 Hz to the reference frequency.
