7kW?\u003c\/strong\u003e No, always match the drive rating to the motor's continuous rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat software configures this servo drive?\u003c\/strong\u003e Use MR Configurator2 from Mitsubishi (free download).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes the drive support absolute position encoding?\u003c\/strong\u003e Yes, when paired with Mitsubishi's absolute encoder motors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs external regenerative resistor required for high-inertia loads?\u003c\/strong\u003e The built-in regenerative brake handles most loads, but large inertial applications may need an external resistor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat happens if ambient temperature exceeds 55°C?\u003c\/strong\u003e The drive will reduce output current or trigger an over-temperature alarm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I use the \u003cstrong\u003eMR-J4-700A\u003c\/strong\u003e in a dirty environment?\u003c\/strong\u003e No, IP20 rating requires installation inside a clean control cabinet.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e© 2026 Ubest Automation Limited. \u003ca rel=\"noopener noreferrer\" href=\"https:\/\/www.ubestplc.com\/\"
