Yes. The EtherCAT Master can control all the physical outputs on the SERVOPACK. However, the SERVOPACK masks output SO1 by default. SO1 is the default output for motor brake (/BK).
In order to control the motor brake output on the EtherCAT SERVOPACK (if using the default parameter for brake assignment Pn50F.2 = 1), the Digital Output Bit Mask (60FE:02) needs to be set to allow writing to that output.
Example: Set 60FE:02 from old value 0x000C0000, to new value 0x000E0000.
After doing that, you will be able to control the brake output with 60FE:01.
If the SERVOPACK status output functions in Pn50E, Pn50F, and Pn510 are assigned, the status will be output using the set value of this function as well as OR logic from the EtherCAT Master value of 60FE:01.
For output mapping, refer to the Digital Outputs (60FEh) section of the user’s manual (Sigma-5 SIEPC72082904 / Sigma-7 SIEPS80000155). The attached PDF shows the Digital Outputs (60FEh) section.
