6.11 Setpoint scaling of the analog input
The setpoint scaling of analog input AI1 depends on the operating mode of the fixed
setpoint processing.
Operating mode
"Mechanical
setting elements"
Setpoint scaling on the operating mode: "Mechanical setting elements":
The following figure shows the setpoint scaling of the analog input AI1:

1) Depending on the selected direction of rotation, the parameter Application limit –
positive speed or the parameter Application limit – negative speed are used to
scale the speed setpoint f1.
For the application limit, refer to the MOVISUITE
®
parameter tree in the following
menu: Functions > Monitoring functions > Limit values > Application limit.
Additional
operating modes
Setpoint scaling on the operating modes:
• "Unipolar/fixed setpoint"
• "Bipolar/fixed setpoint"
• "Fixed setpoint + analog setpoint"
• "Fixed setpoint × analog setpoint"
INFORMATION
In these operating modes, the setpoint scaling is only possible in Expert mode and
with a free configuration of the digital inputs (configuration of the digital inputs ="0").
In these operating modes, the setpoints of the analog input can be adjusted using the
following scaling parameters of the analog input:
• Voltage offset scaling
• Current offset scaling
• Numerator scaling
• Denominator scaling
