Application-Specific FAQ
Q: Is the SGMSS-20A2A-YR12 compatible with the SGDV-200A01A drive?
A: Yes. The SGMSS-20A2A-YR12 is factory-matched to the SGDV-200A01A Sigma-V servo drive. The absolute encoder interface is plug-and-play with Yaskawa’s SigmaWin+ tuning software.
Q: Can this motor be used in a vertical axis application?
A: Yes, with the appropriate holding brake option. The YR12 suffix denotes a straight shaft with key; if a brake is required, specify the SGMSS-20A2A-YR21 (with brake) variant.
Q: What is the maximum cable length between motor and drive?
A: Yaskawa specifies a maximum encoder cable length of 50 m and power cable of 30 m for standard configurations.
Q: Is this motor suitable for food & beverage applications?
A: The IP67 rating makes it suitable for wash-down environments. For direct food-contact zones, consult Yaskawa’s hygienic series options.
Q: Do you provide a warranty?
A: All units carry a 12-month warranty against manufacturing defects from the date of shipment. DOA units are replaced within 5 business days.
