direction «cw/ccw» (depending on the variant) with potentional-free contact.
3.2 5-wire version in 2-wire operating mode
2-wire operating mode can be simulated by short-circuiting the terminals set
value speed input and speed monitor output. Speed is proportional to the
supply voltage (see picture 17).
