Resolution Processing of Sine Cosine Encoders

Valid for S300, S400, S600, S700

Hardware Resolution

The 1 Vss signal is analog buffered with factor 3.3 and evaluated by an AD converter.

1 VSS sincos input ≡ 3.3 VSS AD converter

± 2.5 VAD converter ≡ ± 2048 increments

Software Resolution with S400 and S600

The incremental value of the AD converter is internally multiplied with 4 and can be monitored with the MACRO variables SI4 and CO4.

1 VSS ≡ (4096 Inc • 1V • 3.3 • 4) / 5 V

1 VSS ≡ 10813 Inc

1 VSS ≡ ± 5406 Inc

Software Resolution with S300 and S700

The incremental value of the AD converter is used directly and can be monitored with the MACRO variables SIENC und COENC.

1 VSS ≡ (4096 Inc • 1V • 3.3) / 5 V

1 VSS ≡ 2703 Inc

1 VSS ≡ ± 1351 Inc
