FAQ

What type of drive or inverter is required to operate this DY71S motor?

The DY71S is a permanent magnet synchronous servomotor. It requires a compatible servo drive or frequency inverter with synchronous motor control capabilities, such as an SEW-Eurodrive MOVIDRIVE or MOVIAXIS series drive. It cannot be run directly from a standard 3-phase mains supply.

How is the 230V AC brake controlled?

The brake requires a separate 230V AC supply. It is typically controlled via the servo drive’s brake output through a brake rectifier, like the specified BME1.5. When power is applied, the brake releases; when power is removed, the brake engages. Ensure the control logic is correctly implemented for safe operation.

Can the mounting position (IM M6) be changed?

Yes, SEW-Eurodrive gear motors are designed for various mounting positions. However, changing the mounting position from the specified IM M6 might require adjusting the oil level in the gearbox to ensure proper lubrication. Always consult the official SEW-Eurodrive documentation for the correct oil fill levels for different mounting positions to prevent damage.
