Frequently Asked Questions (FAQ)

• Q: What servo amplifiers work with HG-KR23J?
  A: It pairs with Mitsubishi MELSERVO-J4 series servo amplifiers. For 200W applications, use MR-J4-20A or MR-J4-20B models.
• Q: Does the absolute encoder retain position after power loss?
  A: Yes, the 22-bit absolute encoder retains position data without batteries. No homing required after power cycle.
• Q: Is oil seal protection sufficient for wet environments?
  A: The oil seal protects against light oil mist and splashes. For washdown or submerged applications, use higher IP-rated motors.
• Q: What is the maximum operating temperature?
  A: Operate within 0°C to 40°C ambient temperature. Natural cooling requires adequate airflow around the motor.
• Q: Can I use HG-KR23J with third-party drives?
  A: Mitsubishi recommends pairing with Mitsubishi servo amplifiers for optimal performance. Encoder feedback may require specific protocols.
• Q: What is the inertia classification of this motor?
  A: HG-KR23J features low inertia design. Suited for applications requiring rapid acceleration and frequent start-stop cycles.
