KW Module
The compact inverter
Flexible and functional
The DC link generated by the KE supplies the modular compact inverters KW with energy. For a long service life, a cold plate cools the component with either air or liquid. The KW has a slot for a separately available controller card (KW-R) – seven cards are available, two of them with additional functions for functional safety.
Quick conversion and upgrading
Thanks to the modular concept, the user can replace the controller card at any time or simply upgrade the system to new technology functions after an extended period of operation – without having to change the basic installation.
Double overload
A short-term overload capability provides more power during acceleration or deceleration. This can increase the machine output.
KWD variant –
The compact inverter D, two in one
Compact for small outputs. The double inverter KWD is a KW variant for two servo drives with a maximum output of 5 kVA. It combines two independent compact inverters in a compact housing with cold-plate cooling. The KWD controls two axes and halves the space requirement in the system while offering the same benefits as the KW compact inverter.

Dynamic and precise
Dynamic and precise
The KW digital compact inverter modules control drives in 4-quadrant operation precisely and with high dynamic response. They can be multifunctionally networked with the higher-level controller via various fieldbuses.
