Delta VFD-L Manuals
Hi everyone,
Delta VFD-L (Economy) VFD-L is a variable frequency drive (VFD) produced by Delta Electronics. The "L" in the product name stands for "economy" indicating that this particular VFD-L model is designed for cost-sensitive applications. A VFD-L is an electronic device that controls the speed of an electric motor by adjusting the frequency of the power supplied to the motor. By controlling the speed of the motor, a VFD-L can also control the torque and power output of the motor, which can help save energy and improve the performance of the system in which the motor is used.
The above information describes the various features and settings of the Delta VFD-L (Economy) VFD. This VFD-L model is designed for cost-sensitive applications and has a variety of features to control the speed and torque of an electric motor. The frequency can be set using the ▲▼ keys or a potentiometer, and there are multiple external signal inputs for multi-function operations. There are also different modes of operation that can be set through the keypad or external signals. The VFD-L also has various protection features such as over voltage and under voltage protection, and it is cooled by forced air-cooling. The VFD-L is suitable for use in environments with temperatures between -10℃ to 40℃ and humidity below 90%RH.
The Delta VFD-L (Economy) VFD-L also includes other features such as an Automatic Voltage Regulation (AVR) function that helps to maintain a stable voltage output. The S-curve function allows for smooth acceleration and deceleration of the motor. The VFD-L also has over-voltage stall prevention and DC braking functions, which help to prevent damage to the motor in the event of an over-voltage or over-current condition. The VFD-L also has a fault records feature that allows you to view past faults and troubleshoot the system. Additionally, the VFD-L has adjustable carrier frequency, starting frequency setting of DC braking and over-current stall prevention, momentary power loss restart, and frequency limits. To protect the settings and parameters, the VFD-L also includes a parameter lock/reset function.
The VFD-L also has a number of protection features, including over-voltage, over-current, under-voltage, and overload protection, as well as electronic thermal and over-heating protection. The VFD-L also has a self-testing function that checks the VFD's internal circuits for proper operation. The VFD-L also includes an EMI filter that helps to reduce electromagnetic interference.
The VFD-L is designed for use in environments with altitudes of 1,000 meters or below, and it should be kept away from corrosive gases, liquids and dust. The VFD-L is also designed to withstand vibration of up to 9.80665m/s2(1G) less than 20Hz, and 5.88m/s2 (0.6G) at 20 to 50Hz.
It is important to note that the above information is based on the manufacturer's specifications and may vary depending on the specific model or application. It is recommended to always refer to the manufacturer's documentation for the most accurate and up-to-date information.
