Control Techniques SP2401

The Control Techniques SP2401 is an advanced AC servo drive designed for high-performance applications. It is part of the Unidrive SP series, known for its reliability and flexibility. The drive is capable of operating efficiently in various industrial environments, offering precise control over motor functions.

Technical Description:

The SP2401 model operates within an ambient temperature range of 0°C to 50°C. It requires forced convection for cooling to maintain optimal performance. The drive supports input voltage ranges from 380 V to 480 V with a tolerance of ± 10 %.

It can also operate with a 200 V to 240 V input voltage with the same tolerance, ensuring versatility in different power supply conditions. The frequency range for the drive is 48 to 62 Hz. The drive's maximum continuous input current for single-phase is 18.3 A, while for three-phase it is 20 A.

The output current must be de-rated at ambient temperatures between 40°C and 50°C to ensure safe operation. The drive also features ingress protection with options for IP00 when no gland plates are fitted and IP10 or IP40 with cable glands fitted.

The SP2401 supports three-phase power with a maximum supply imbalance of 2 % negative phase sequence. This translates to a 3 % voltage imbalance between phases, which helps maintain stability and performance. The drive also features a heatsink fan that operates at 115 V or 230 V single-phase AC, ensuring adequate cooling during operation.

Storage and Installation Considerations:

The SP2401 drive offers a maximum storage temperature range from -40°C to 50°C. For sizes 1 and 2, the capacitors need re-forming after 12 months, while for sizes 3, 4, and 5, re-forming is required after 4 years. This maintenance requirement ensures the longevity and reliability of the drive in long-term storage scenarios.

The drive is designed to operate at altitudes up to 4,000m. However, when installed between 1,000 m to 4,000 m, the output current must be de-rated by 1 % per 100 m above 1,000 m. For instance, at 4,000 m, the output current needs to be de-rated by 30 %.

Standard Operating Precautions:

When operating the SP2401, it is essential to adhere to the specified environmental conditions to avoid overheating or damage. Ensure that the ambient temperature does not exceed 50°C and that the drive is adequately ventilated. Regular maintenance, such as capacitor re-forming, should be conducted as per the manufacturer's guidelines to maintain performance and longevity.

Frequently Asked Questions:

What is the ambient temperature range for the Control Techniques SP2401?

The SP2401 operates within an ambient temperature range of 0 °C to 50 °C. It requires forced convection cooling to maintain optimal performance. De-rating is necessary at temperatures above 40 °C.

How does the SP2401 handle high altitude installations?

The SP2401 can operate at altitudes up to 4,000 m. Between 1,000 m and 4,000 m, de-rate the output current by 1 % per 100 m above 1,000 m. At 4,000 m, the de-rating is 30 %.

What are the ingress protection ratings for the SP2401?

The ingress protection rating is IP00 without gland plates. With gland plates and cable glands fitted, it can be IP10 or IP40. This flexibility allows customization based on installation needs.
