MDX61B0022-5A3-4-00 is a high-performance AC drive from SEW-EURODRIVE MOVIDRIVE MDX61B series. With a rated power of 2.2 kW for constant torque applications, it is designed for speed, torque and basic positioning control of three-phase asynchronous and synchronous motors. This standard version is equipped with a built-in Class C2 EMC filter and integrated brake chopper for four-quadrant operation, and it adopts non-conformal coated PCB, which is suitable for clean and dry standard industrial environments.

MDX61B stands for MOVIDRIVE B series high-performance drive, equipped with two expansion slots for encoder and fieldbus modules. The code 0022 indicates the rated motor power of 2.2 kW under constant torque load and 3.0 kW under variable torque load. 5A3 means the drive supports three-phase 380 V to 500 V AC power supply and integrates a Class C2 EMC filter. The digit 4 represents the built-in brake chopper to realize four-quadrant operation. The suffix 00 refers to the standard version with non-coated printed circuit board and basic IPOSplus® motion functions.

The drive accepts three-phase 380 V to 500 V AC input voltage with a tolerance range of minus 15 percent to plus 10 percent, and the applicable grid frequency is 50 Hz or 60 Hz. The rated input current is 5.5 A. The rated output power is 2.2 kW for constant torque operation and 3.0 kW for variable torque operation, with rated output current of 5.5 A and apparent power of 3.8 kVA. The adjustable output frequency ranges from 0 Hz to 599 Hz. It has excellent overload capability, which can run continuously at 200 percent rated current for 60 seconds and 175 percent rated current for 2 seconds. The default PWM carrier frequency is 4 kHz, and users can select 8 kHz or 16 kHz according to on-site requirements. The internal brake chopper requires an external braking resistor with resistance no less than 47 ohms. The integrated EMC filter fully complies with Class C2 requirements of EN 61800-3 standard.

The product protection class is IP20, so it must be installed inside a closed control cabinet. The overall dimension is 105 mm in width, 314 mm in height and 234 mm in depth, and the total weight is approximately 3.5 kg. It adopts temperature-controlled forced air cooling to ensure stable heat dissipation. The allowable operating ambient temperature ranges from minus 10 degrees Celsius to plus 50 degrees Celsius. Power derating is required for long-term continuous operation when the ambient temperature exceeds 40 degrees Celsius. The storage temperature ranges from minus 25 degrees Celsius to 70 degrees Celsius. For installation altitude below 1000 meters, no power derating is needed. If the altitude is higher than 1000 meters, derate the output power by 1 percent for every additional 100 meters. The internal PCB has no conformal coating for standard working conditions.

Three control modes are available to meet different application demands. VFC open-loop V/f control is applied to general speed regulation scenarios. CFC closed-loop vector control provides high torque output and outstanding speed control accuracy. Servo control mode can be activated when matched with an external encoder, which is ideal for driving permanent magnet synchronous motors.

This unit is embedded with IPOSplus® Basic motion system, supporting basic positioning, electronic cam operation, master-slave synchronization, flying restart and DC braking functions. A built-in PID controller realizes closed-loop regulation for process parameters such as pressure and flow. Two reserved expansion slots support the installation of encoder modules and various fieldbus modules for function expansion. The drive is also fitted with STO Safe Torque Off function that meets PL d industrial safety standard.

The drive is equipped with analog input terminals that support plus or minus 10 V and 4 to 20 mA signal input. It provides six channels of 24 V DC isolated digital inputs, two transistor digital outputs and one relay output. A dedicated interface is reserved for connecting motor PTC thermistor to monitor motor operating temperature in real time.

Standard communication interfaces include SBus system bus and RS485 bus compatible with Modbus RTU protocol. Users can expand communication functions such as PROFINET, CANopen and EtherCAT by installing optional fieldbus modules to achieve data exchange with upper control systems.

Comprehensive protection mechanisms are integrated into the drive to prevent equipment damage caused by abnormal operating conditions. It provides protection against overcurrent, overvoltage, undervoltage and internal overtemperature. It also detects ground fault and short circuit effectively. The motor overtemperature can be monitored via external PTC thermistor signals. Once a fault is triggered, the drive will send out alarm signals and perform safe stop immediately. The operating status and specific fault codes can be displayed on the onboard panel for troubleshooting.

The drive features compact structure and high power density, which saves installation space inside control cabinets. Closed-loop vector control ensures stable low-speed high-torque performance and high control precision. The built-in STO safety function meets strict industrial safety requirements. Rich basic motion functions reduce the need for additional external controllers. Modular design enables flexible function expansion to adapt to diverse automation projects. The integrated Class C2 EMC filter simplifies on-site wiring and guarantees electromagnetic compatibility.

This drive is widely used in various industrial automation fields, including conveying systems, packaging machinery and material handling equipment. It is also suitable for energy-saving speed regulation of fans, water pumps and compressors. It can drive three-phase asynchronous motors and synchronous motors with demands on speed regulation and basic positioning control in clean and dry working environments.

This product has passed CE certification complying with EN 61800-3 and EN 60204-1 standards. It also obtains UL, cUL and RoHS certifications.

The 00 standard version uses non-coated PCB and carries basic IPOSplus® motion functions, designed for clean and dry indoor industrial environments. In contrast, the 0T version adopts conformal coated PCB and supports advanced IP
