MDX61B0014-5A3-4-00 is a high-performance AC drive from SEW-EURODRIVE MOVIDRIVE MDX61B series, with a rated power of 1.5 kW. It is designed for speed, torque and basic positioning control of three-phase industrial motors. This unit is equipped with a built-in Class C2 EMC filter and integrated brake chopper to support four-quadrant operation. As the standard version with non-conformal coated PCB, it is applicable to clean and dry indoor industrial environments.

MDX61B represents the high-performance drive series with two expansion slots for encoder and fieldbus modules. The code 0014 stands for the rated motor power of 1.5 kW. 5A3 means the drive is compatible with three-phase 380 V to 500 V AC power supply and integrates a Class C2 EMC filter. The digit 4 indicates a built-in brake chopper for four-quadrant operation. The suffix 00 refers to the standard version with non-coated printed circuit board and basic motion control functions.

The drive works with three-phase AC input voltage ranging from 380 V to 500 V, with a permissible voltage deviation of minus 10 percent to plus 10 percent, and the applicable frequency is 50 Hz or 60 Hz. The rated input current is 3.6 A. It delivers rated output power of 1.5 kW for constant torque applications and 2.2 kW for variable torque applications, with rated output current of 4.0 A and apparent power of 2.8 kVA. The adjustable output frequency covers the range from 0 Hz to 599 Hz. It features strong overload capacity, which can operate 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 actual demands. The internal brake chopper requires an external braking resistor with resistance no less than 68 ohms. The integrated EMC filter complies with Class C2 standard of EN 61800-3.

The product protection class is IP20, so it must be installed inside a control cabinet. The overall dimension is 105 millimeters in width, 260 millimeters in height and 95 millimeters in depth, and the total weight is approximately 2.8 kilograms. It adopts temperature-controlled forced air cooling for stable heat dissipation. The allowable operating ambient temperature is from 0 degrees Celsius to 50 degrees Celsius. Power derating is required for 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 power by 1 percent for every additional 100 meters. The internal PCB is non-coated for standard working conditions.

Three main control modes are available for different application requirements. VFC open-loop V/f control is suitable for general speed regulation tasks. CFC closed-loop vector control provides high torque output and excellent speed control accuracy. Servo control mode is available when matched with an external encoder, which is ideal for driving permanent magnet synchronous motors.

This drive is embedded with IPOSplus® basic motion system, supporting 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 allow users to install encoder modules and various fieldbus modules to expand system functions.

For signal connections, the drive is fitted with analog input terminals that support plus or minus 10 V and 4 to 20 mA signals. It has 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 temperature in real time.

Standard communication interfaces include SBus system bus and RS485 bus which supports Modbus RTU protocol. Users can expand communication functions such as PROFINET and CANopen by installing optional fieldbus modules to achieve data exchange with upper control systems. The unit also integrates STO Safe Torque Off function that meets PL d safety standard.

Comprehensive protection mechanisms are integrated into the drive to prevent equipment damage. It can effectively protect against overcurrent, overvoltage, undervoltage, internal overtemperature, ground fault and short circuit. It also monitors motor overtemperature via external thermistor signals. Once a fault is detected, the drive will trigger alarm signals and perform safe stop immediately. Operating status and specific fault codes can be displayed on the onboard panel.

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 industrial safety requirements. Rich standard motion functions reduce the need for additional external controllers. Modular design enables flexible function expansion to adapt to diverse automation projects. The integrated EMC filter simplifies on-site wiring and ensures electromagnetic compatibility.

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

This product has passed CE certification complying with EN 61800-3 and EN 60204-1 standards. It also obtains UL 508C, CSA and RoHS certifications.

The 00 standard version uses non-coated PCB and carries basic motion functions, designed for clean and dry industrial environments. In contrast, the 0T version adopts conformal coated PCB and supports advanced motion functions, which is suitable for harsh working sites with dust, moisture and mild corrosive gas. Users can select the proper version based on on-site environment and functional requirements.
