Select speed setpoint
In case of terminal control in the preset control mode "Terminals 0":
• In the Lenze setting, the main speed setpoint is selected via the analog terminal X3/A1U (e.g. via
a setpoint potentiometer).
• Scaling: 10 V ≡ 100 % reference speed (C00011) ≡ 1500 rpm
(applies to 4-pole asynchronous motors)
In case of keypad control:
1. Navigate to parameter C00728/3.
2. Set the desired setpoint speed in [%] with regard to the reference speed set in C00011 (CCW
rotation: -199.99 % .... 0, CW rotation: 0 ... +199.99 %).
In order to prevent jumps, the main speed setpoint is led via a ramp generator with linear ramps:

Using fixed setpoints
Alternatively to the setpoint selection via the analog input or C00728/3. "fixed setpoints" can also
be activated according to the following truth table:
• Fixed setpoints refer to the reference speed set in C00011.

LOW LOW 0 0 The setpoint speed is selected via the analog input 1 or with
keypad control via C00728/3.
HIGH LOW 1 0 Setpoint speed = fixed setpoint 1 (C00039/1: 40 %)
LOW HIGH 0 1 Setpoint speed = fixed setpoint 2 (C00039/2: 40 %)
HIGH HIGH 1 1 Setpoint speed = fixed setpoint 3 (C00039/3: 40 %)
