Dynamic Braking Unit B150
The Dynamic brake permits to control the regenerated energy for series SD750 (integrated in frames 1
and 2). B150 dynamic brake activates an IGBT to discharge the DC bus with external resistors when
the DC voltage overpasses a pre-set value. This activation signal can also be sent by the drive in slave
mode from the common fiber optic port included in the control board.
The B150, with reduced dimensions and high reliability, is the main power-switching device of such
dynamic braking systems.
Communication boards
SD750 family is compatible with the most commonly used communication protocols (Profibus-DP,
Profinet, Modbus TCP, Ethernet IP, CAN Open, Field Bus, etc.), thanks to its optional boards.
