- 0 - 10V with remote potentiometer option *
- 0 - 10V with external reference *
- 4 - 20mA with external reference *
- reference with internal potentiometer (CVI - VMA option)
- limitation of maximum speed with internal potentiometer (CVI - VMA option)
• Digital reference
- 1 to 3 preset speeds (accessible with the parameter-setting option **)
Speed regulation
Regulation of a reference with the integrated PI loop (accessible with the parameter-
setting option **)
