Hello!
To control the G120C, I use SPEED AXIS as a motion control object (standard Telegram 1).
I want to use SETAXISSTW to control bits 8 and 9 (for JOG), but they aren't set, although the status after execution was set to done without error. The other bits (11 - 15)  are set and cleared normally with SETAXISSTW, but not 8 and 9. The manual says that the instruction can change bits 8, 9, and 11-15.
To set Bit 8, I write 16#100 for STW1 and STW1BitMask.
To set Bit 9, I write 16#200 for STW1 and STW1BitMask.
Other instructions that could overwrite STW1 aren't executed, if I'm not mistaken.
What could be the problem with setting these bits? 
P.S.
If I understand correctly, I can't use the SINA_SPEED FB in portal version 20, right?
Thanks
