Professional FAQ

• Q: What is the main advantage of the built-in regenerative resistors? A: They safely absorb excess energy from the motor during deceleration, improving system efficiency and reducing heat.
• Q: Can this amplifier run two motors at once? A: No, the MR-J3-15KB-LR is designed to control one high-power servo motor.
• Q: What kind of cable is needed for the SSCNET III/H connection? A: You need a dedicated fiber-optic cable designed for the SSCNET III/H protocol.
• Q: Is an external transformer required for the power supply? A: Not if your facility's line voltage is already between 200-230V AC. Always verify your local power conditions.
• Q: How do I know if the forced cooling is working? A: The cooling fan will activate based on temperature. Ensure air vents are never blocked for proper operation.
