Speed-setpoint monitoring

Function
The speed setpoint comprises:
• Speed setpoint of the position controller
• Speed setpoint portion of the feedforward control (with active feedforward control only)
• Dift compensation (only for drives with analog setpoint interface)
Figure 2-5 Speed setpoint calculation
The speed-setpoint monitoring ensures by limiting the control or output signal (10V for analog setpoint interface
or rated speed for digital drives) that the physical limitations of the drives are not exceeded:
