Product description
At 62 mm wide, the Control Techniques DST1401 occupies little installation space within the Digitax ST range; its height and depth are 322 and 226 mm respectively, and the unit weighs 2.1 kg. The AC servo drive operates from a three-phase 380–480 V supply at 48–65 Hz. The DST1401 variant is rated for 1.5 A output current and a short-term peak current of up to 4.5 A. On the input side, 2.6 A is specified as the typical continuous current and 2.8 A as the maximum continuous current. Forced convection cooling dissipates heat losses; maximum drive losses of 79 W are specified at a 6 kHz switching frequency. The enclosure has an IP20 rating. Its documented environmental conditions are dry and non-conductive with pollution degree 2. The permissible operating range is 0–50 °C, with current derating required above 40 °C. The servo drive provides an adjustable speed reference with a documented output speed range of up to 40,000 min⁻¹. The preset speed reference has a resolution of 0.1 min⁻¹, while 0.001 min⁻¹ is specified for the precision reference. After power-up, the start-up time until the motor is ready is 4 seconds. Within the Digitax ST family, the DST1401 belongs to the 400-V model group with a three-phase supply; its cooling system and IP20 enclosure are part of the documented design.
