Configuring speed setpoint
Eight sources in total are available for speed setpoint. You can select one of them with the
combination of digital input signals SPD1, SPD2 and SPD3:

7.6.1.1
Speed control with external analog speed setpoint
In the S mode, when the digital input signals SPD1, SPD2 and SPD3 are all at low level (0),
analog voltage from the analog input 1 is used as the speed setpoint.
The analog voltage from the analog input 1 correponds to a parameterized speed value.
Default speed value is rated motor speed. The analog voltage of 10 V corresponds to the
maximum speed setpoint (V_max) and this maximum speed setpoint can be specified by
parameter p29060.
