What is the adjustment range for the speed reference input in the Altivar 58 drive?

The range is set by the low speed (LSP) and high speed (HSP) settings in menu 2 (SEt - adjustments menu).
Therefore, if the LSP is set to a value greater than 0 Hz the lowest valid speed reference will be the LSP setting.
See the attached keypad programming guide for additional details.

*Note: It may be helpful to notice the deadband (blS) and pedestal (bnS) settings in menu 4. They can be used to change how the drive responds to the analog input signal with respect to low speed.
