New energy saving modules KCM from Kollmorgen support the DC-link

Using regenerative braking to save energy and bridge power interruptions: two new intelligent Kollmorgen devices improve performance in multi-axis systems. The KCM-P is an active support module for DC intermediate circuits.

With no complex installation required, the KCM-P stores kinetic braking energy using a novel robust capacitor technology to act directly on the intermediate circuit as a UPS for short-term power interruptions, keeping the DC-link voltage intact. As a dynamic energy storage module for regenerative braking, the KCM-S is easily installed when compared to complex energy storing solutions. The energy stored in the capacitor module during regenerative braking is made available for the next acceleration cycle. With storage and recovery made directly to the DC bus, there is no interfering harmonics when power is required. A third option, the KCM-E, combines the benefits of both regenerative energy modules.

KCM modules (capacitor modules) absorb kinetic energy generated by the motor when it is operating in generator mode. Normally, this energy is dissipated as waste via brake resistors. These modules however, feed the energy they have stored back into the intermediate circuit as and when it is required. The modules are available in 3 different versions.

KCM-S saves energy: The energy stored in the capacitor module during regenerative braking is available the next time acceleration happens. The module’s inception voltage is calculated automatically during the first load cycles.

KCM-P power in spite of power failure: If the power supply fails, the module provides the servo amplifier with the stored energy that is required to bring the drive to a standstill in a controlled manner (this only applies to the power supply voltage; battery-back up, the 24V supply separately).

KCM-E expansion module for both applications. Expansion modules are available in two capacitance classes. The modules can be combined as required.
