7 Drive Machine Data (SIMODRIVE Drive MD) 07.97
7.3.2 Drive MD (data description)
Note regarding bit 9:
Incorrect parameterization, e.g. not on EQN MD 1011 (configuration actual-value acquisition,
indirect measuring system)
or MD 1030 (configuration actual-value acquisition, direct measuring system)
or obsolete hardware (not suitable for EQN)
or no encoder connected
or incorrect encoder cable (for ERN instead of for EQN).
