MOTOROLA MVME61006E-0161 Channel isolation card

When the motor is braking, energy is fed back to the servo amplifier. This energy is converted into heat in the ballast resistor. The ballast resistor is switched in by the ballast circuit. The maximum ballast power depends on the ballast resistor which is used and the ballast power set in the software. If you would like some help with dimensioning the ballast power required for your system, please talk to our applications department.

Functional description: 

- Single amplifier, not coupled via the intermediate circuit (DC+, DC-) The circuit starts to respond from a intermediate circuit voltage of 720V. If the power which is fed back from the motor is higher than the ballast power level which is set, then the servo amplifier signals the status “Ballast power exceeded” and the ballast circuit switches itself off. At the next internal check of the intermediate circuit voltage (a fraction of a second later) an overvoltage will be recognized and the controller will switch off with an error message “Overvoltage
