7.22 Safe Brake on X50
The connector X50 provides the link to the safe brake. If a brake is configured, it is monitored by the SBC (safe brake
control) function. The following table gives information about the pinout and the requirements for the safe brake.
The brake can be connected directly or a brake control unit can be used in between. The electrical characteristics listed
in the table below correspond with the brake output signals on X50.

Stripping length: 10 mm
Use brake, which is engaged when not powered.
Use 24 V brake or valve, capable for 100 % duty cycle.
Maximal current: 0.8 A
At 24 V a minimal current of 10 mA must flow
The brake must be active (braking) when the current is equal or below 10mA.
Brake must be tolerant for test pulses of 1 ms, where no current is driven.
