Maximum cable length of the brake control
The maximum permissible cable length of 300 m between the Safe Brake Adapter 230 V
AC and the brake must be observed. To accurately calculate the maximum cable length,
see the SINAMICS Low Voltage Engineering Manual on the customer DVD supplied with
the device.
Fast de-energization
In some cases, DC brakes are operated with an upstream brake rectifier (230 V AC input
side) for fast de-energization. Some brake rectifier types are equipped with two additional
connections for switching the brake load on the DC side. This allows the brake coil to be
quickly de-energized, i.e. braking starts earlier.
The Safe Brake Adapter supports such fast de-energization using the two additional
connections -X15:1 and -X15:2, which are designed to control a contactor. In turn, the relay
is responsible for switching the brake current on the DC side. This function does not belong
to safe brake control.
