Note: The data outputs will all turn OFF as soon as the main power supply turns OFF. Data is not saved.

*1. An inrush current of approximately 8 A will flow for approximately 6.5 ms when the power is turned ON.

*2. Negative values for multi-turn absolute values are express as two's complements (see code at right).

*3. Multi-turn data will change approximately 10 μs after single-turn data. Allow for this when reading data.

E6C-N_Spec1

*4. When the power supply is interrupted, multi-turn detection is not performed and multi-turn data is
compensated by comparison to the data that existed before the power supply was interrupted. If a rotation
operation exceeding ±80° is performed from the position when the main power supply turns OFF, correct
multiturn data will be lost. The application must be set up so that no rotation operations are performed that exceed this stipulation.

*5. Output when the multi-turn counter exceeds the -128 to 127 counting range. This error flag will be reset if the count data returns to within the counting range.

*6. The single-turn data and multi-turn data reset signals can be input independently to reset the single-turn data to address 0 and the multi-turn data to 0 rotations.

*7. Use an Encoder cable length of 10 m max. When using a cable of 10 m or less, read the code 10 μs or more
after the LSB (2º)of the code changes.

*8. The device coupled to the Encoder shaft must also satisfy the ambient temperature condition.

The expressions for negative values given above can be achieved by reversing 1's and 0's and then adding 1.
