Installation Guidelines

• Shaft Alignment: Ensure precise coupling alignment between the keyway shaft and the driven machinery to prevent excess radial or axial forces on the motor bearings.
• Thermal Management: Maintain unobstructed airflow around the motor body to ensure the ambient temperature does not exceed 40 degC during continuous operation.
• Brake Wiring: Connect the electromagnetic holding brake to a dedicated, surge-protected control circuit. Do not use the holding brake for dynamic deceleration or stopping.
• Cable Routing: Separately route the power and feedback cables to mitigate electromagnetic interference (EMI) and ensure reliable signal transmission.
