Encoder and Feedback System

The Mitsubishi HG-SR202BJ includes a 22-bit absolute encoder. This encoder provides very high positioning accuracy. You do not need a home search after power loss. The absolute feedback saves time and improves safety. This feature is essential for precision motion control systems.

Environmental Protection and Durability

This servo motor carries an IP67 rating. It resists dust ingress completely. It also withstands temporary water immersion. The HG-SR202BJ works reliably in harsh industrial environments. You can use it in washdown areas or dusty factories. The robust housing protects internal components effectively.

Brake System

The Mitsubishi HG-SR202BJ has an integrated electromagnetic brake. This brake holds the motor shaft when power is off. It prevents vertical axes from falling due to gravity. The brake adds safety for lifting and holding applications. Use this feature for conveyors, elevators, and robotic arms.

Mounting and Connection

This motor uses 176 x 176 mm flange mounting. The flange provides stable and secure installation. Two MS-Type connectors simplify wiring. These connectors are industry-standard and easy to mate. You can connect power and feedback cables quickly. Proper mounting reduces vibration and improves motor life.

Inertia and Load Matching

The HG-SR202BJ features medium inertia. This inertia level balances responsiveness and stability. It matches well with medium-capacity loads. You can accelerate and decelerate smoothly without overshoot. The motor handles dynamic applications with ease. Medium inertia also reduces tuning difficulty for new users.

Installation Guidance

Follow these steps for proper installation of the Mitsubishi HG-SR202BJ.

1. Prepare Mounting Surface: Clean the 176 x 176 mm flange area.

2. Secure Motor: Bolt the motor firmly to the machine frame.

3. Connect Cables: Attach both MS-Type connectors securely.

4. Wire Brake Circuit: Connect the electromagnetic brake to a proper supply.

5. Ground the Motor: Use the ground terminal for electrical safety.

6. Set Encoder Zero: Follow Mitsubishi software for initial encoder setup.

Do not hammer the motor shaft during installation. Use only specified cables for the HG-SR202BJ. Keep the motor away from coolant spray when possible.

Frequently Asked Questions (FAQ)

Q1: Can the HG-SR202BJ operate without the electromagnetic brake?
A1: No, the HG-SR202BJ has a factory-integrated brake. You must wire and use it properly. The motor does not operate correctly if the brake is locked.

Q2: What is the difference between 2000 rpm and 3000 rpm operation?
A2: The HG-SR202BJ runs continuously at 2000 rpm. It reaches 3000 rpm only for short periods. Check your duty cycle before using maximum speed.

Q3: Does the HG-SR202BJ work with any Mitsubishi servo drive?
A3: The HG-SR202BJ works best with Mitsubishi MR-J4 or MR-J5 series drives. Verify drive compatibility before purchase.

Q4: How do I reset the 22-bit absolute encoder after battery replacement?
A4: You need Mitsubishi software to reset the encoder. The HG-SR202BJ requires absolute position initialization after battery change.

Q5: Is the IP67 rating valid with both MS-Type connectors attached?
A5: Yes, the Mitsubishi HG-SR202BJ maintains IP67 only with mated connectors. Unmated connectors break the seal. Always cap unused connectors.
