Overview
For SINAMICS S120, S150, G130 and G150 units, a Safe Brake
Adapter SBA is required to safely control a motor holding brake
via the Safe Brake Control (SBC) safety function according to
IEC 61800-5-2.
The Safe Brake Adapter is available for a 230 V AC brake
control voltage.
It can be ordered as supplementary component for
SINAMICS S120 chassis format units as well as for
SINAMICS G130 units.
Note:
The SBA is approved for the IEC area. Safe Brake Adapter with
UL approval are available on request. The UL approval is valid
for a maximum permissible current consumption of 1.5 A
(inductive).
■
Design
The Safe Brake Adapter SBA has the following connections
and interfaces:
•
1 connection for the connecting cable to the Power
Module/Motor Module
•
1 connection for the external 230 V AC supply
•
1 connection for motor holding brake
•
1 connection for fast de-excitation
