Application-Specific FAQ
Q: Is the UGRMEM-01SNQ72 compatible with SGDV (Σ-V) amplifiers?
A: No. The Σ-III motor connector and encoder protocol differ from Σ-V. Use SGDH or SGDS amplifiers. Cross-series use requires a conversion cable and parameter adjustment — contact our engineers for guidance.
Q: Can this motor be used in a vertical axis application without a brake?
A: The UGRMEM-01SNQ72 has no integrated brake (N suffix). For vertical axes, a separate external brake or counterbalance mechanism is required to prevent load drop on E-stop or power loss.
Q: What is the maximum cable length between motor and amplifier?
A: YASKAWA specifies a maximum of 20 m for encoder cable and 30 m for power cable with standard wiring. Longer runs require shielded cable and may need a line driver booster.
Q: Is IP67 rating maintained after shaft seal wear?
A: IP67 is rated for new units. In continuous rotation applications with coolant exposure, inspect the shaft seal annually and replace per YASKAWA’s maintenance schedule.
Q: Do you provide YASKAWA test reports or factory certificates?
A: Yes. Factory test reports and certificates of conformance are available for all units. Request at time of order via [email protected].
