FAQ
Q1: What is the Allen-Bradley MPL-B320P-MK72AA used for?
A1: This servo motor is designed for industrial automation systems that require accurate positioning, controlled movement, and consistent rotational speed. Typical applications include packaging machines, material handling equipment, automated assembly lines, and precision manufacturing systems.
Q2: What is the rated speed of the MPL-B320P-MK72AA?
A2: The motor has a rated speed of 5,000 RPM and a maximum speed of 5,000 RPM. It is suitable for high-speed motion control applications requiring stable motor performance.
Q3: Does the MPL-B320P-MK72AA have an integrated brake?
A3: No. This model does not include an integrated holding brake. Applications that require the motor shaft to remain stationary when power is removed may need an external braking or mechanical holding solution.
Q4: What type of feedback encoder does this motor use?
A4: The MPL-B320P-MK72AA uses a multi-turn high-resolution absolute encoder with 1024 Sin/Cos cycles per revolution and Hiperface feedback. This provides position information for accurate motion control and positioning.
Q5: What is the difference between MPL-B320P-MK72AA and MPL-B320P-MJ72AA?
A5: Both models belong to the same MP-Series MPL motor family and share similar electrical and feedback specifications. The main difference is the shaft configuration. The MK72AA has a keyless shaft extension, while the MJ72AA uses a keyed shaft extension. Both models are supplied without an integrated brake.
Q6: Which servo drives are compatible with the MPL-B320P-MK72AA?
A6: This motor can be used with compatible Allen-Bradley Kinetix and Ultra servo drive platforms. Supported drive families include Kinetix 5500, 6200, 6500, 6000, 300, 350, 2000, 7000, and Ultra 3000. Actual compatibility should be confirmed against the drive’s electrical and feedback requirements.
Q7: What are the dimensions and weight of the MPL-B320P-MK72AA?
A7: The motor has a 100 mm frame size and a 50.8 mm magnet stack length. Its approximate listed weight is 3.71 kg (8.18 lbs). For installation planning, check the official mechanical drawing for the complete motor length, shaft dimensions, and mounting measurements.
Q8: What should be checked when replacing the MPL-B320P-MK72AA?
A8: Before replacement, verify the complete catalog number, voltage rating, motor speed, encoder type, keyless shaft configuration, connector arrangement, and mounting dimensions. The replacement motor must also match the existing servo drive’s feedback and electrical requirements to ensure reliable operation.
