Procedure without application class or for the application class [0]: Expert

The wizard only displays the "setpoint input" if you con󹪝gured a converter with PROFINET or

PROFIBUS interface.

Select whether the converter is connected to a higher-level control via the 󹪝eldbus.

Select whether the ramp-function generator for the speed setpoint is implemented in the

higher-level control or in the converter.

Select the control mode.

Further information is provided at the end of the section.

Select the I/O con󹪝guration to preassign the converter interfaces.

Factory setting of the interfaces (Page89)

Default setting of the interfaces (Page92)

Set the applicable motor standard and the converter supply voltage.

Application:

• "[0] Load cycle with high overload ..." for applications requiring a high dynamic performance,

e.g. conveyor systems.

• "[1] Load cycle with low overload ..." for applications that do not require a high dynamic

performance, e.g. pumps or fans.

If an optional component is installed between converter and motor, the corresponding

setting must be performed.

If a braking resistor is installed, you set the maximum braking power to which the braking

resistor will be subjected.

Select your motor.

Enter the motor data according to the rating plate of your motor.

If you have selected a motor based on its article number, the data has already been entered.

De󹪝ne whether the converter actuates a motor holding brake.

Set the most important parameters to suit your application.

Application:

• [0]: In all applications that do not fall under [1]…[3]

• [1]: Applications involving pumps and fans

• [2]: Applications with short ramp-up and ramp-down times. However, this setting is not

suitable for hoisting gear and cranes/lifting gear.

• [3]: Applications involving pumps and fans with optimized e󹪟ciency. The setting only makes

sense for steady-state operation with slow speed changes. We recommend setting [1] if load

surges in operation cannot be ruled out.

• [5]: Applications with high breakaway torques, e.g. extruders, mills and mixers
