5.5.7 Dynamic Drive Control

Procedure for application class [2]: Dynamic Drive Control

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 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.

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]: Recommended setting for standard applications.

• [1]: Recommended setting for applications with ramp-up and ramp-down times < 10 s. This

setting is not suitable for hoisting gear and cranes.

• [5] Recommended setting for applications with a high break loose torque.

Motor data identi󹪝cation:

• [0]: No motor data identi󹪝cation

• [1]: Recommended setting. Measure the motor data at standstill and with the motor rotating.

The converter switches o󹪜 the motor after the motor data identi󹪝cation has been completed.

• [2]: Default setting: Measure the motor data at standstill. The converter switches o󹪜 the

motor after the motor data identi󹪝cation has been completed.

Select this setting if the motor cannot freely rotate, e.g. for a mechanically limited traversing

range.

• [3]: Measure the motor data while the motor is rotating. The converter switches o󹪜 the motor

after the motor data identi󹪝cation has been completed.
