SEN Signals
•
Wait at least three seconds after turning ON the power before
raising the SEN signal to high level.
•
When the SEN signal is changed from low level to high level, the
multi-turn data and initial incremental pulses are transmitted.
•
The motor cannot be operated until these operations are completed,
regardless of the status of the servo ON signal (/S-ON).
Note:
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.
