Product Description:

The Sanyo Denki developed 68ZBM140HBJ70 Servo motor for industrial automation. It operates specifically for precision motion control operations that are part of the ABS Super Servo Motor Series. The servo motor delivers STO (Safe Torque Off) capabilities, which strengthens operational safety.

The 68ZBM140HBJ70 Servo motor functions using 400V AC power to deliver dependable and efficient operational performance. This motor incorporates a 23-bit battery-less absolute encoder. This delivers high precision feedback for precise measurement of position. The motor operates between 3000 RPM rated speed and 6500 RPM maximum speed. It allows users to adapt to multiple industrial functions. The motor maintains durable characteristics because it withstands up to 4.9 m/s² of vibrations. The servo motor works at operating temperatures between 0°C and 40°C. The 68ZBM140HBJ70 Servo motor integrates well into machinery due to its small size while featuring a 130mm flange opening. Safety is ensured through the integrated 24V DC holding brake on the motor. The motor stands ready to handle both dust and water intrusion as it is protected by an IP65 rating while operating within demanding circumstances. This servo motor forms an effective combination with SANMOTION R series amplifiers to achieve optimal operational performance.

This 68ZBM140HBJ70 Servo motor reaches 4.77 Nm for its rated torque. However, the motor produces 14.3 Nm of peak torque, which suits powerful application needs. The design of low inertia contributes to quick acceleration, together with deceleration. The user must test insulation resistance (with a 500V megohmmeter) prior to first use or after extended storage. The resistance must be ≥5 MΩ to prevent winding damage. Ground the motor and drive separately to prevent leakage currents and electrical noise. Disengage power and wait a minimum of 5–15 minutes prior to handling the motor to discharge capacitors thoroughly and to avoid electric shock.

Frequently Asked Questions about 68ZBM140HBJ70:

Q: How does the 68ZBM140HBJ70 motor handle electrical noise in installations?

A: Separate grounding of motor and drive reduces leakage currents and mitigates electrical noise. This improves signal integrity and system performance.

Q: What role does the 24V DC holding brake play in the 68ZBM140HBJ70 Servo motor?

A: The integrated brake holds the motor shaft in place when power is off. This is crucial for vertical axis operations and safety-critical applications.

Q: How does the 130mm flange of the 68ZBM140HBJ70 benefit machinery integration?

A: The standardized 130mm flange simplifies mounting compatibility. It facilitates direct integration into a wide variety of industrial setups.

Q: Why should insulation resistance be tested in the 68ZBM140HBJ70 motor before use?

A: Testing ensures windings are intact and moisture hasn't degraded insulation. This prevents startup failures and prolongs motor life.

Q: How does the IP65 rating benefit the Sanyo Denki 68ZBM140HBJ70 motor?

A: The IP65 rating ensures protection against dust and water ingress. This enables the motor to operate reliably in harsh industrial settings.
