Panel fit and power rating
The Omron R88D1SN55FECT is a 5.5 kW servo drive from the 1S series, delivering 16 A continuous rated current to drive medium-power servo motors in a compact 200 mm wide, 180 mm tall, 235 mm deep package. The IP20 protection rating means it is designed for indoor panel mounting where the enclosure provides the environmental seal — not for washdown or outdoor locations. Operating ambient range of 0 to 55 °C sets the thermal budget for the cabinet; forced ventilation or a larger enclosure may be needed if other heat sources push the internal air above 55 °C.
Supply voltage and motor matching
The AC input range spans 323 to 504 V, covering 400 V class supplies with margin for brown-out conditions or weak grids — common in industrial installations where line voltage sags under load.
