Description
Control Techniques UNI1401
The Control Techniques UNI1401 is an advanced AC servo drive designed to meet the demanding needs of modern industrial applications. This product offers high performance, reliability, and precision, making it ideal for a wide range of automation tasks.
Technical Description:
The UNI1401 servo drive has a nominal rating of 0.75 kW or 1.0 hp. It supports various switching frequencies, with maximum permissible continuous output currents ranging from 2.1 A at 3 kHz to 2.1 A at 12 kHz for 40 °C ambient conditions.
At 50°C, the permissible output current remains at 2.1 A across the same frequency range. This ensures the drive can maintain performance under varying thermal conditions.
Power dissipation for the UNI1401 is consistent, with a maximum total power dissipation of 80W at 3 kHz and 90 W at frequencies from 6 kHz to 12 kHz. The typical input current is 3.0 A, and the maximum continuous input current is 4.5 A. The heatsink fan for the UNI1401 operates on either 115 V or 230 V single-phase AC with a frequency range of 48 to 62 Hz. The fan current varies, with 1.02 A at 50 Hz 1.36 A at 60 Hz for 115 V, and 0.51 A at 50 Hz, and 0.68 A at 60 Hz for 230 V.
AC Supply Requirements:
The UNI1401 operates with an AC supply voltage of 380 V to 480 V ± 10 % or 200 V to 240 V ± 10 %, suitable for various industrial power standards. It requires a three-phase supply and accommodates a frequency range of 48 to 62 Hz. The maximum supply imbalance is limited to a 2 % negative phase sequence, ensuring stable performance even with minor supply variations.
Accuracy and Resolution:
The drive offers precise control with an open-loop frequency resolution of 0.1 Hz for preset frequency references and 0.001 Hz for precision frequency references. The open-loop frequency accuracy is maintained at 0.03 Hz or 0.01 % of the reference value, whichever is larger.
In closed-loop operations, the preset speed reference is 1rpm, with a precision speed reference of 0.01rpm. This high level of accuracy ensures precise motor control and optimal performance in applications requiring fine adjustments.
Standard Operating Precautions:
When operating the UNI1401, it is essential to adhere to specific precautions to ensure safety and longevity. Ensure the AC supply voltage and frequency are within the specified ranges. Avoid exceeding the maximum permissible continuous output current to prevent overheating.
Regularly check the phase sequence and supply imbalance to maintain optimal performance. Use appropriate fuses or circuit breakers as per the rated specifications to protect the drive from electrical faults.
