Description
The Safe Brake Control (SBC) is a safety function, that is used in safety-related applications,
e.g. in presses or in rolling mills. In the current-free state, the brake acts on the motor of the
drive by spring force. The brake is released when current flows (=low active).
The maximum brake current is 2 A.
The Safe Brake Adapter 230 VAC is installed in the cabinet unit in the factory. An infeed is
connected to terminal -X12 on the Safe Brake Adapter to provide the necessary power. For
control, a connection is established between the Safe Brake Adapter and the Control
Interface Module using a cable harness installed in the factory.
For controlling the brake, a connection must be established on site between terminal -X14 on
the Safe Brake Adapter and the rectifier of the brake. It is not permissible that AC brakes are
directly controlled.
NOTICE
Device failure as a 24 V DC brake has been connected
When a 24 VDC brake is connected to option K88 (Safe Brake Adapter 230 VAC) this can
damage the Safe Brake Adapter and cause the device to fail (when the brake closes this is
not displayed by an LED, the fuses can then trip, the relay contact service life is reduced).
• Do not connect a 24 VDC brake to the 230 VAC Safe Brake Adapter.
Note
Maximum cable length of the brake control
The maximum permissible cable length of 300 m between the Safe Brake Adapter 230 VAC
and the brake must be observed. To accurately calculate the maximum cable length, see the
SINAMICS Low-Voltage Configuration Manual on the customer DVD supplied with the
device.
