Marginal conditions
● The third handwheel must be connected before the activation, because the axis can drift
● Incorrect parameterization of the measuring circuit connection or missing hardware
● In contrast to actual-value encoders, there is no encoder monitoring with connected
● There is no interlocking for dual assignment of an actual-value input. Therefore, in
● The third handwheel can only be operated after the SIMODRIVE 611D bus has been

principle, it is possible to assign an actual-value encoder used for position/speed sensing
as "third handwheel" at the same time. In this case, the "handwheel pulses" are evaluated
according to the encoder resolution (coarse increments).
