I had to configure watchdog settings on a few SEW drives half a year
ago, which worked fine.

The only registers I know, that are needed to change the WD behavior are
0x400, 0x420 and 0x80x (WD bits in SM configurations). If these places
contain the correct values, I don't know any reasons why it shouldn't
work.

Does TwinCAT do anything else when configuring the slave?

I always depends on the slave if it is possible to enable/disable the
WDs.
