Frequently Asked Questions (FAQ)

• Q: Can MR-J4-60B operate with single-phase power only?
  A: Yes, it supports both 1-phase and 3-phase 200-240 VAC mains. For 1-phase, connect to terminals L1 and L2.
• Q: What motors are compatible with MR-J4-60B?
  A: It pairs with Mitsubishi MELSERVO-J4 series AC servo motors (0.6 kW rated capacity). Use HG-KR or HG-SR series motors for optimal performance.
• Q: Does the amplifier include dynamic braking?
  A: Yes, MR-J4-60B features a built-in dynamic brake for safe deceleration during faults or emergency stops.
• Q: What safety function does MR-J4-60B offer?
  A: It provides STO (Safe Torque Off) compliant with IEC/EN 61800-5-2. This function prevents the motor from generating torque without removing main power.
• Q: What is the ambient temperature range for installation?
  A: Operate between 0°C to +55°C (32°F to 131°F) with 90% RH or less non-condensing. Store between -20°C to +65°C.
• Q: Is the MR-J4-60B suitable for CNC machinery?
  A: Absolutely. Its high-precision control suits CNC, robotics, pick-and-place, and general factory automation.
