7.1.1.1 Selection of the main speed setpoint
The main speed setpoint is selected in the Lenze setting via the analog input 1.
• Scaling: 10 V ≡ 100 % reference speed ( C011 )
• The main setpoint is transformed to a speed setpoint in the setpoint encoder via a ramp func-
tion generator with linear or S-shaped ramps.
• For a detailed functional description see FB L_NSet_1 . ( 230)

7.1.1.2 Motor potentiometer function
Alternatively, the main speed setpoint can be generated via a motor potentiometer function.
• In the Lenze setting, the motor potentiometer function is deactivated.
• Activation is possible via
C806 or via the bMPotEnable input.
• The behaviour of the motor potentiometer during switch-on of the drive system can be selected
in C805 .
• For a detailed functional description see FB L_MPot_1 . ( 226)
7.1.1.3 Process controller
A process controller (PID controller) is connected downstream of the setpoint generator.
• In the Lenze setting, the process controller is deactivated.
• The activation is executed by selecting the operating mode in
C242 .
• For a detailed functional description see FB L_PCTRL_1 . ( 233)
