With parameter SP .0 „Setpoint and rotation selection" the required setpoint source
and the corresponding rotation source can be linked (see Fig. 6.4.2).

Set Value and Ramp Adjustment
The setpoint can be preset with the following sources:
– analog (REF1)
– digital absolute (SP .1)
– digital in per cent (SP .2)
– motorpoti (see chapter 6.8.4)
– analog direct (fast setpoint setting)
Concerning the rotation sources it must be differentiated between
three possible preadjustments:
1. Direction of rotation by way of parameter SP .3 „Digital rotation
setting"
Set values: SP .3
0
1
2
2. Direction of rotation by way of terminal strip X2
The direction of rotation can be adjusted by way of assigning
terminal forward or reverse. If both terminals are assigned at
the same time then direction of rotation forward has priority.
Connection / Activation of direction of rotation see Chapter
6.3 „Digital In- and Outputs".
3. Direction of rotation through sign of setpoint
For analog signals by adjusting positive or negative voltages
and for digital signals by adjusting positive or negative values.
