Product Description:

The R2AA04010FXP1CM is an AC servo motor developed by Sanyo Denki under the SANMOTION R series. It supports torque, speed and position control through compatible SANMOTION R amplifiers. The R2AA0 servo motor has integrated encoder and brake into the motor housing to simplify system integration and wiring.

The R2AA04010FXP1CM servo motor attains cooling through natural convection and has an insulation system rated Class F to allow safe operation within a temperature range of –10°C to +40°C. It operates in humidity conditions ranging from 20% to 80% RH. The R2AA0 servo motor has IP67 protection rating to allow use in environments exposed to dust and temporary water immersion. It includes a DC 24V holding brake that engages on power loss to ensure secure position retention in vertical or load-sensitive applications. The R2AA0 servo motor incorporates a 13-bit incremental encoder that provides 8192 pulses per revolution for precise position and speed control. Its encoder uses differential line driver output with A, B and Z phases to deliver reliable signal transmission even in environments with electrical noise. The R2AA0 servo motor configuration supports closed-loop feedback systems in advanced automation machinery.

The R2AA04010FXP1CM servo motor is designed for 200V AC input and has a rated 100 watts power consumption along with a continuous torque of 0.318 Nm. It draws a rated current of 0.81 amperes and operates at a maximum speed of 3000 revolutions per minute. The R2AA0 servo motor features a 40mm square mounting flange and is equipped with a round shaft without a key or oil seal. It is CE certified to meet international safety and performance standards.

Frequently Asked Questions about R2AA04010FXP1CM:

Q: Why is a 13-bit encoder used in the R2AA04010FXP1CM?

A: A 13-bit encoder offers 8192 pulses per revolution, enabling fine-grain position feedback for smoother and more accurate servo control in complex automation systems.

Q: How does differential line driver output help the R2AA04010FXP1CM motor?

A: It provides noise-immune signal transmission, ensuring reliable feedback even in environments with high electromagnetic interference.

Q: What advantage does natural convection cooling offer in the R2AA04010FXP1CM?

A: It eliminates the need for external fans or forced air, reducing maintenance while enabling silent and compact integration into tight enclosures.

Q: Why does the R2AA04010FXP1CM have no key or oil seal on the shaft?

A: A round shaft without a key or seal is ideal for precision couplings and simplifies installation where contamination protection isn’t a concern.

Q: Why is a holding brake important in the R2AA04010FXP1CM servo motor?

A: The 24V DC brake engages on power loss, making it crucial for vertical-axis applications where position must be retained without drift or back-driving.
