HI

I have a D425 and a couple of double motor modules 6SL3120-2TE13-0Axx that drive siemens braked motors 1KF7032-xAK7xCxx

The application I am looking at requires the system confirm the status of the brake, does the unit have a native brake check function?

can anybody point me in the right direction to find out what brake checking you have or can get with these units?

I have an extended licence for this unit

Thanks

Andy

Andy,

the safety brake check as the Bosch-Rexroth driver has for vertical axis is not provided in the Siemens driver as preconfigured solution.
The easiest way I can suppose is to manage the brake with an additional relay interrupting the brake wire and engagé a torque sequence as soon as the safety sofware require.

During this phase the additional output for the brake is off and the test is positive until the limit stroke as defined isn't reached. In cse of unwanted stroke means that the brake is loosing the effect and an additional warning has to rise up in the safety software.
