Control Techniques SP2404 The Control Techniques SP2404 is an efficient servo drive that offers high performance and reliability. This drive is a member of the Unidrive SP series, which is known for its flexibility, scalability, and comprehensive feature set. It is engineered to provide precise control of servo motors, enhancing the efficiency and productivity of automated systems. The SP2404 is ideal for demanding environments, offering robust performance under various operational conditions. Technical Description: The SP2404 model can handle a maximum continuous input current of 27.6 A for both single-phase and three-phase configurations. To ensure safe operation, it requires appropriate fuses rated at 32 A for IEC gG and 30 A for UL standards. The device supports cable sizes of 6 mm² for both input and output as per EN60204 standards, and 8 AWG for input and 8 AWG for output according to UL508C standards. Regarding output performance, the SP2404 is designed for both normal and heavy-duty operations. Under normal duty, it can handle a maximum continuous output current of 29 A, supporting motor power of up to 15 kW at 480V and 20 kW at 230 V. For heavy-duty applications, the drive manages a continuous output current of 29 A, with motor power capabilities of 15 kW at 480 V and 10 kW at 230 V. Key Environmental Specifications: The SP2404 integrates several key features to enhance its functionality and usability. It operates within a wide temperature range of 32 °F to 122 °F, with a minimum temperature at power-up of -10 °C (14 °F). The drive employs forced convection cooling to maintain optimal performance and reliability. It can also operate effectively in high humidity environments, with a humidity tolerance of 95 % non-condensing at 40 °C (104 °F). The drive's storage capabilities are also notable. The storage temperature range is between - 40 °F to 122 °F, ensuring the drive remains functional and protected during long periods of inactivity. Line Filters: Another important consideration is the use of line reactors. These reduce the risk of damage to the drive from severe disturbances on the supply network, such as power factor correction equipment connected close to the drive, or large DC drives with ineffective line reactors. Direct-on-line started motors connected to the supply can cause excessive peak currents, potentially leading to nuisance tripping or drive failure. Implementing line reactors helps mitigate these risks, ensuring stable and reliable operation. Frequently Asked Questions: What is the maximum continuous output current for the SP2404 in normal duty?
