Capacitor and Braking Resistor

Description

The drive has an internal capacitor and an internal braking resistor. If the internal capacitor and the internal braking resistor are insufficient for the dynamics of the application, one or more external braking resistors must be used.

The resistance values for external braking resistors must not be below the specified minimum resistance. If an external braking resistor is activated by means of the appropriate parameter, the internal braking resistor is deactivated.
