Signal Levels
High level: 4.0 V min.; Low level: 0.8 V max.
D Let at least three seconds elapse after turning on the power before raising the SEN signal to
high level.
D When the SEN signal is changed from low level to high level, the multi-turn data and initial
incremental pulses are output.
D Until these operations are completed, the motor cannot be operated regardless of the status
of the servo ON signal (/S-ON).
If for some reason it is necessary to turn OFF a SEN signal that is already ON, and then to turn it back ON again,
maintain the high level for at least 1.3 seconds before turning it ON and OFF.
