The control circuit also takes 1-phase 200–240 V AC, so you don't need a separate transformer for the logic power. The interface side expects a regulated 24 V DC supply, ±10 %, and needs 500 mA capacity including the CN8 connector signals. That 500 mA covers the encoder and brake hold-off; undersizing the 24 V supply is a common commissioning trip. ## Safety and compliance — what the ratings mean Protection class I per IEC/EN 61800-5-1 means the drive requires a protective earth connection — the PE terminal is not optional. Overvoltage category III (IEC/EN 60664-1) tells you it's rated for fixed-installation distribution-level transients, so it can sit downstream of a branch circuit without additional surge suppression. The STO (Safe Torque Off) input shuts off energy in 8 ms — that's the time from the STO signal going low to the power stage being inert, which matters for a risk assessment under ISO 13849-1.","metaTitle":"Mitsubishi MR-J4-60A Servo Amplifier, 200-240V AC, 500mA Int","metaDescription":"Mitsubishi MR-J4-60A servo amplifier, 1/3-phase 200-240V AC input, 500mA 24V DC interface.
