[Speed Thresh Pos]
Threshold speed for the drive above or below which the value of Par 393
[Speed Threshold] changes. When the speed of the drive exceeds the value of
this parameter, Par 393 [Speed Threshold] displays “Above Thresh” (0). When
the speed of the drive is below the value of this parameter, Par 393 [Speed
Threshold] displays “Below Thresh” (1).

[Speed Thresh Neg]
Threshold speed for the drive above or below which the value of Par 393
[Speed Threshold] changes. When the speed of the drive exceeds the value
specified in this parameter, Par 393 [Speed Threshold] displays “Above
Thresh” (0). When the speed of the drive is below this threshold, Par 393
[Speed Threshold] displays “Below Thresh” (1).

[At Speed Error]
Defines the speed above and below the speed reference (in Par 118 [Speed
Reg In]) at which the value of Par 394 [At Speed] changes. When the
difference between the speed reference and the actual speed is greater than
the value of this parameter, Par 394 [At Speed] displays “Not Equal” (0).
When the difference between the speed reference and the actual speed is
less than the value of this parameter, Par 394 [At Speed] displays “Equal” (1).
