Baumuller has been pursuing a policy of energy efficiency in developing controllers. These controllers , which do not convert energy into heat when motor brakes are applied. The benefits of a regenerative system can be felt in particular on machines running in reversing duty, where sudden acceleration followed by deceleration is typical. Baumuller regenerative converters have some technical features such as: the active front-end devices in the b maxx 4100 series, which are suitable for universal use, make energy regeneration possible in any system. The ability to feed energy back into the system creates huge potential for savings at high power ratings in particular. B maxx 4100 controllers can be used for power ratings between 35 kw and 180 kw. The benefits of a regenerative system can be felt in particular on machines running in reversing duty, where sudden acceleration followed by deceleration is typical. These converters have some technical features for: Monitoring the charging circuit and main contactors as well as for synchronisation with the frequency of the supply system. Current controlled precharging on the b maxx 4100 boasts a number of advantages over resistive charging: when a unit powers up, for example, the charging time is monitored and faults are detected and reported. This means that troubleshooting can be performed even before the machine starts up, thus preventing damage to the machine or drive. The controlled charging current means that the converter is protected against short-circuits. Even enabling the main contactor will not generate an uncontrolled current rush. External charging resistors are not necessary for mounting in a control cabinet and adaptation to the dc-link capacitance is not required.This regenerative system it makes sense to use b maxx 4100 regenerative converters on large machine tools or grinding machines.
