4.3 kW continuous, 27 A peak — the duty envelope that matters
The LXM62DD27G21000 is a single-axis servo drive from the PacDrive 3 family, rated 4.3 kW continuous power with a continuous output current of 9 A at 4 kHz switching frequency. Its 3-second peak capability reaches 27 A at 4 kHz — this is the figure that governs acceleration and deceleration torque in high-inertia loads like rotary indexing tables or unwinding stations. Supply voltage is flexible: three-phase 400 V (-10…+10 %) or three-phase 230 V (-10…+10 %), and even single-phase 230 V for lower-power commissioning or test stands. The 50/60 Hz tolerance is tight at ±5 %, so a poor-quality site supply needs a line reactor ahead of the drive.
STO SIL 3 PLe and SERCOS III — safety and motion bus integration
Safe Torque Off (STO) is integrated per IEC 61800-5-2, certified to SIL 3 (IEC 61508) and PLe (ISO 13849-1). This eliminates the need for an external safety contactor on the motor power circuit — the drive's own hardware removes torque without removing mains power. The safety function is self-monitoring; a fault on the STO channel forces the drive into a safe state. Communication is via integrated SERCOS III, a real-time Ethernet motion bus. The drive synchronises position and velocity loops across the ring topology with deterministic jitter — essential for multi-axis electronic gearing or cam profiles. The two digital inputs and two digital outputs (24 V DC) handle local handshaking; the two touch-probe inputs capture position latches for registration mark sensing.
Obsolete — sourcing through independent channels
Schneider Electric has marked the LXM62DD27G21000 as obsolete. The drive carries a full suite of compliance documentation: UL 508C, CSA C22.2 No 14, IEC 61800-5-1/-2/-3, IEC 62061, IEC 61508, and ISO 13849-1/-2. This means it was originally certified for North American and European industrial machinery markets — the paperwork for a replacement-in-kind should already be in the machine file.
Mounting and environmental constraints
The drive measures 44 mm wide by 310 mm high by 270 mm deep — a slim profile that fits a standard 400 mm deep enclosure with room for the SERCOS III cabling bend radius. IP20 protection means it is intended for a clean, dry cabinet; the ambient operating range is 5…55 °C with 5…85 % relative humidity. Above 1000 m altitude, derate 1 % per 100 m. Vibration resistance is 10 m/s² and shock resistance 100 m/s² per IEC 60721-3-3 — adequate for machine-mounted cabinets on presses or packaging lines, but not for direct mounting on a vibrating conveyor frame without isolation mounts. Pollution degree 2 (non-conductive dust only) confirms the cabinet must be gasketed against conductive particulates.
