Variable Frequency Drive AT3-2200X Overview This compact three-phase VFD delivers precise, high-torque motor control for motors up to 2.2 kW. It uses a closed-loop V/F control method with optimized PWM and electromagnetic compatibility to provide smooth speed regulation, low noise, and reduced electromagnetic interference. Built-in protections and a robust design improve reliability in challenging power and environmental conditions. Key benefits High torque and precise speed control across a wide speed range for demanding applications. Stable operation under poor mains quality, temperature, humidity, and dust conditions. Low noise and reduced electromagnetic interference thanks to optimized PWM control and EMC design. Easy installation and wiring using screw terminals. Effective heat dissipation with an integrated cooling fan and large heatsink. Multiple protection functions to prevent downtime: over-current, over-voltage, under-voltage, over-heat, and short circuit protection.

Protection and reliability Over-current protection Over-voltage protection Under-voltage protection Over-temperature protection Short-circuit protection I O and communication 485+/485-: RS485 communication port COM: common terminal VI1: external analog voltage input 0-5V or 0-10V CI: external current input 4-20 mA SP1, SP2: open collector outputs 1 and 2 5V/10V: 20 mA power output 15V/24V: 15V or 24V power input and 200 mA power supply output Relay output rating: 250 VAC 5 A or 30 VDC 3 A (TC) Terminal note: TA and TB are NC, TA and TC are NO Terminal inputs (wire control) X6: input terminal 6 (wire control CW/CCW switch). X6 connects to COM, input signal is effective. X5: input terminal 5 (wire control CCW). X5 connects to COM, input signal is effective. X4: input terminal 5 (wire control CW). X4 connects to COM, input signal is effective. X3: input terminal 3 (speed range 3). X3 connects to COM, input signal is effective. X2: input terminal 2 (speed range 2). X2 connects to COM, input signal is effective. X1: input terminal 3 (speed range 3). X1 connects to COM, input signal is effective. Important setup notes When adjusting parameters, the VFD must be stopped or parameter changes will not be saved. New and old product versions may be shipped randomly. Please ensure this is acceptable before ordering. Typical applications Conveyor drives where consistent torque and accurate speed control are required for material handling. Pumps and fans where variable speed reduces energy use and allows process tuning. Small machine tools and automation equipment that require precise motor control and reliable protection. What is included 1 x Variable Frequency Drive AT3-2200X Care and compatibility Check motor compatibility: designed for three-phase motors up to 2.2 kW. Ensure correct three-phase AC 380V supply and proper wiring per the terminal instructions. Allow slight differences in color or dimensions due to lighting, screen settings, and manual measurement.
