Standard: No suffix = standard (17-bit incremental encoder, keyway+thread+oil seal)

Special suffixes:

SS = brake version (per esempio., ECMA-C20604SS)

RC = 3m extended cable (per esempio., ECMA-C20807RC)

R6 = 16mm shaft (per esempio., ECMA-C20604R6)

RH = keyway, no center thread

ECMA series has been upgraded to the ECM series for high-speed ASDA-B3/E3/A3 systems. New order format:

5. Key Selection & Procurement Tips
6. Model matching: Ensure drive series (A2/B2) matches motor series (C1/C2) to avoid incompatibility.
7. Shaft selection:

RS = standard (key+thread+oil seal, no brake)

SS = with brake (required for vertical axes)

RC = 3m extended cable

3. Codificatore: Default 17-bit incremental; absolute type requires custom order.
