It then means:
Full torque
MomRed = 0000
––> k = 1 (i.e. 1
P1230 and 1
P1235 are effective)
No torque
MomRed = FFFF
––> k = 1 – 65535 / 65536 = 0.0000153 or almost 0
with a total of 65536 intermediate steps.
When P0881 is parameterized > 25 %, then it is possible to reduce to
precisely 0.
The 2 analog outputs of a drive can be controlled using these control
words.

Note:
It is only possible to control the analog outputs via PROFIBUS–DP if the
appropriate signal number is specified in P0626 or P0633.
The parameters available to parameterize the analog outputs, are still
valid (refer to Chapter 6.7).
