Omron R88D-GN04H-ML2 AC Servo Driver 400W 200-240V 1-Phase G-Series MECHATROLINK

Omron R88D-GN04H-ML2 is a compact G-Series AC servo driver designed for high-performance motion control in industrial automation systems. This unit is new, never used and in excellent cosmetic condition, with only minor handling marks from storage, and has not been installed or wired in a system.

Item details

• Brand: Omron

• Model: R88D-GN04H-ML2 AC Servo Driver

• Control method: MECHATROLINK-II network type (ML2)

• Rated output power: 400 W (0.4 kW)

• Drive supply: 200–240 V AC, single-phase, 50/60 Hz

• Output: approx. 107.9 V, 3-phase to servo motor

• Rated output current: about 2.7 A continuous, higher peak current for acceleration

• Matching motor example: Omron R88M-G40030H-BS2, 400 W, 200 V, 3000 rpm, 1.3 Nm, with brake (not included)

• Frequency range: 0–333.3 Hz output to motor

• Encoder interface: serial incremental/absolute encoder via CN2 connector

• Communication connectors: MECHATROLINK-II (CN6A/CN6B), RS-232 (CN3) for parameter setting and monitoring

• Main terminals: L1, L2 (L3 not used for 1Ø), L1C/L2C control power, U/V/W motor output, B1/B2/B3 regen resistor, PE earth

• Mounting: base-mounted, compact footprint for control panels

Features and benefits

• High-response frequency up to around 1 kHz for accurate positioning and smooth speed control.

• Integrated MECHATROLINK-II fieldbus reduces wiring and allows multi-axis synchronous control from a motion controller.

• Built-in autotuning and load inertia detection simplify commissioning, even for users upgrading or replacing older drives.

• Multiple protection functions (overvoltage, undervoltage, overcurrent, overload, regeneration overload, overheat) help protect your machine and motor.

Condition and packaging

• Condition: New, never used, removed from spare-parts stock. No signs of installation on the mounting plate or terminals.

• The original retail box is not included; the drive will be carefully packed in antistatic material and strong outer packaging for safe shipment.

Typical applications

Suitable for use in CNC machinery, packaging lines, pick-and-place systems, conveyors and general automation where a 400 W Omron G-Series servo motor is required. The R88D-GN04H-ML2 is also a good replacement unit for existing Omron installations using MECHATROLINK-II motion networks.
