This parameter is a symmetrical limit on both directions of rotation.
Defines drive absolute maximum frequency reference. Slip compensation and current limit can increase the motor frequency further.
Used in unipolar mode to define drive minimum set speed. This can be overridden if the maximum set speed clamp Pr 21.01 is adjusted to be less
than Pr 21.02. Inactive during jogging.
This parameter is used to select a speed reference for motor 2 as follows:
0: AI.AV Analog reference 1 or 2 selected by terminal input
1: AV.Pr Analog reference 1 (voltage) or Presets selected by terminal input
2: AI.Pr Analog reference 1 (current) or Presets selected by terminal input
3: Pr Preset reference selected by terminal
4: PAd Keypad reference selected
5: Prc Precision reference selected
When this parameter is set to 0 the reference selected depends on the state of bit parameters Pr 1.41 to Pr 1.44. These bits are for control by digital
inputs such that references can be selected by external control. If any of the bits are set, the appropriate reference is selected (indicated by Pr 1.49).
If more than one bit is set the highest numbered will have priority.
In modes 1 and 2 a preset speed will be selected instead of the voltage or current selection, if the preset selected is any preset speed other than
preset speed 1. This gives the user the flexibility to be able to select between voltage and 3 presets, or current and three presets, with only two digital
inputs.
