About Adjustable Frequency Drives
In all range of sizes, a set of finely fabricated Adjustable Frequency Drives are offered by us. This kind of devices are used for controlling the speed of an electric motor. These systems can be usually operated at constant speed, which also make them power efficient in nature. In comparison to other traditional methods or devices, their installation and usage contribute in saving the energy. Offered Adjustable Frequency Drives are capable of reducing the initial current, which enable the utilization of supply connections and comparatively smaller fuses, which lower down the loads on electronic network. At compatible rates these variable drives can be availed by our clients.

FAQ's of Adjustable Frequency Drives:
Q: How do I program the adjustable frequency drive for different motor speeds?
A: The drive is programmed via a user-friendly keypad, allowing you to set parameters directly on the digital LCD display. Adjust speed, acceleration, and other functions easily to match your application's requirements. No external software is necessary.
Q: What types of motors are compatible with this frequency drive?
A: This frequency drive is designed specifically for squirrel cage induction motors and is optimized for three-phase, 380 to 480 V AC input. Ensure your motor matches these specifications for best performance.
Q: Where is the ideal installation location for the drive in an industrial setting?
A: It should be panel-mounted in a clean, non-condensing environment within the operating temperature range of -10C to +40C. The drive is suitable for industrial automation, supporting altitudes up to 1000 meters without derating.
Q: What process should I follow to connect and configure the drive?
A: Mount the drive securely using the panel mounting hardware and connect power and output wires via screw terminals. Configuration is done through the digital keypad, enabling parameter adjustments for control method, frequency, and safety features.
Q: How does the built-in brake unit benefit industrial applications?
A: The built-in brake unit provides fast and controlled stopping of the motor, which is essential in applications requiring frequent starts, stops, or quick emergency halts, improving both safety and process control.
Q: What safety features are available on this adjustable frequency drive?
A: It comes equipped with overload and overheating protection, EMC compliance (EN61800-3), IP20 enclosure rating, and a built-in brake unit, ensuring reliable and safe operation even in demanding environments.
Q: When should the drive be considered for replacement or maintenance?
A: Regular inspection is advised, particularly monitoring cooling and terminal connections. Maintenance or replacement is recommended if you notice increased noise, display anomalies, or reduced efficiency, typically after many years of use due to its robust ABS and polycarbonate construction.
