PowerFlex 4 2.2 kW AC Drive 22A-D6P0N104

Overview

22A-D6P0N104 is an inverter of the PowerFlex 4 series. It is commonly used for variable speed control of AC motors. The adapted motor power is 2.2 kilowatts (3 horsepower). The input is three-phase 480 volt AC, the output rated current is 6 amps, the operating frequency range is 50 – 60 Hz, and the power factor reaches 0.98. It can stably output power to drive industrial equipment. It also has a voltage tolerance rate of ±10% and a frequency tolerance rate of 47 – 63 Hz, adapting to different power grid environments. It is equipped with an integrated keyboard and LED display to facilitate on-site parameter configuration and status viewing; it supports voltage/frequency ratio control method, and also has 1 independent isolated analog input, 3 fixed digital inputs and 2 programmable digital inputs, which can flexibly connect to various control signals.

FAQ:

1.The rated output current of 22A-D6P0N104 is 6A and is suitable for 2.2kW motor. Do I need to adjust the parameters if I drive a 1.5kW motor?

It is feasible for 22A-D6P0N104 to adapt the inverter of 2.2kW motor to drive 1.5kW motor, but the core parameters must be adjusted, otherwise it may cause motor protection failure, abnormal heating, etc.

Required parameters:

1. Motor rated parameters: Change the rated current and power of the original 2.2kW motor in the frequency converter to the nameplate value of the 1.5kW motor (for example, the rated current of a three-phase 380V 1.5kW motor is about 3.4A), and correct the rated frequency simultaneously (if there is a difference).
2. Overload protection parameters: Set the protection threshold at 1.2 times the rated current of the 1.5kW motor to avoid protection failure.

Optional optimization parameters:

1. Torque parameters: Fine-tuning torque boost for constant torque loads, no adjustment required for variable torque loads.
2. Acceleration and deceleration time: shorten appropriately to reduce current impact and mechanical impact.

2.The protection level of 22A-D6P0N104 is IP20. Can it be installed directly in a dusty workshop site, or does it have to be used with a control cabinet?

22A-D6P0N104 cannot be installed directly in dusty workshop sites and must be used with a control cabinet:

1. The core reason why it cannot adapt to dusty environments: The IP20 dustproof rating can only block the intrusion of medium-sized foreign objects with a diameter greater than 12.5 mm, and cannot block dust at all. On the other hand, fine dust in a dusty workshop will penetrate into the inside of the inverter in large amounts. On the one hand, it may adhere to core components such as circuit boards and cooling fans, causing poor heat dissipation, causing the inverter to trigger protection shutdown due to overheating. On the other hand, it may also cause internal circuit short circuits, damage key components such as IGBTs, and seriously affect equipment life and operational safety. In addition, this model is required to be installed in a dry, ventilated and non-corrosive gas environment, and the dusty environment itself is beyond its scope of application.
2. Core requirements for matching control cabinets: The core purpose of matching control cabinets is to improve the overall dust-proof capability. It is preferred to choose a dust-proof control cabinet with a protection level ≥ IP5X. This type of cabinet can block the entry of most dust. If the dust concentration in the workshop is extremely high, it is recommended to choose an IP6X dust-tight control cabinet, which can almost completely block dust intrusion. At the same time, it should be noted that the control cabinet needs to reserve reasonable heat dissipation openings and be equipped with dust-proof filters to prevent the inverter from malfunctioning due to heat accumulation in the confined space. The wiring joints need to be treated with seals to prevent dust from penetrating through the gaps in the cable interfaces.
