8.4.1.1 Setpoint channel
Setpoint addition
Fine tuning (correction variable) often needs to be carried out on site for applications in which
the command variables are generated by central control systems.
You achieve the correction variable using the addition point for the main and additional setpoint
in the setpoint channel. Both variables are imported simultaneously via two separate or one
setpoint source and added in the setpoint channel.
Adjustable parameters
Parameter Setting
p1070 Main setpoint
p1071 Main setpoint scaling
r1073 Main setpoint effective
p1075 Supplementary setpoint
p1076 Supplementary setpoint scaling
r1077 Supplementary setpoint effective
r1078 Total setpoint effective
These parameters concern connector inputs to which the setpoint values are connected.

Direction reversal
A reversal of the rotational direction is necessary under the following conditions:
● When the drive should be operated in both directions of rotation.
● If the cables were connected with an incorrect phase sequence.
Note
Note that only one direction of rotation is enabled in the factory setting.
