MDX61B refers to the high-performance vector and servo drive series equipped with multiple option slots, which supports closed-loop vector control and servo control functions. The code 0005 stands for the rated motor power of 0.55 kW. 5A3 indicates the drive is designed for three-phase 380 V to 500 V AC power supply and comes with a built-in Class C2 EMC filter. The digit 4 means an integrated brake chopper is fitted to realize four-quadrant operation. The suffix 00 represents the standard version with uncoated printed circuit board and basic IPOSplus® positioning function, intended for regular indoor working environments.

The drive operates with a three-phase input voltage ranging from 380 V to 500 V AC with a tolerance of minus 10 percent to plus 10 percent, and the applicable power frequency is 50 Hz or 60 Hz. The rated input current is 1.8 A. The rated output power is 0.55 kW with an apparent power of 1.4 kVA and rated output current of 2.0 A. The output frequency can be adjusted from 0 Hz up to 599 Hz. It features strong overload capacity, supporting 200 percent rated current operation for 60 seconds and 175 percent rated current operation for 2 seconds. The PWM carrier frequency is adjustable among 4 kHz, 8 kHz and 16 kHz, and 4 kHz is set as the default value. The integrated brake chopper is standard on this model, and a braking resistor with a minimum resistance of 68 ohms needs to be connected externally for normal braking performance.

This drive provides multiple control modes including open-loop VFC control, closed-loop CFC vector control and servo control to meet different speed and motion control demands. It is built with the STO Safe Torque Off safety function that complies with PL d safety standard. The standard IPOSplus® positioning and sequence control function enables basic single-axis positioning tasks. It also integrates practical functions such as automatic motor parameter tuning, flying restart and DC braking, which improves operation stability and convenience. There are reserved option slots for installing extended modules like encoder cards and mainstream fieldbus communication cards.

It is equipped with analog input terminals that support 0 to 10 V and minus 10 V to plus 10 V signal for speed reference setting. Multiple isolated 24 V DC digital input channels and programmable digital output channels including transistor outputs and one relay output are configured for signal collection and external device control. Standard communication interfaces cover SBus and RS485 which supports Modbus RTU protocol. Users can expand communication functions such as Profinet and EtherNet/IP by adding optional modules to achieve data interaction with upper control systems. The drive also reserves interfaces for connecting motor thermistor sensors to realize real-time motor temperature monitoring and protection.

The protection class of the drive is IP20, so it must be installed inside control cabinets. It adopts forced air cooling mode with a built-in temperature controlled fan to ensure stable heat dissipation. The allowable operating ambient temperature ranges from 0 degree Celsius to 45 degree Celsius. Power derating is required if the ambient temperature exceeds 45 degree Celsius. The storage temperature ranges from minus 25 degree Celsius to plus 70 degree Celsius. The overall dimension is 105 mm in width, 260 mm in height and 95 mm in depth, and the total weight is approximately 3.1 kilograms.

The drive is equipped with comprehensive protection mechanisms to secure the whole system. It can detect and respond to faults including overcurrent, overvoltage, undervoltage, drive overtemperature, ground fault and short circuit. It also monitors motor overtemperature through external thermistor signals. Once any fault occurs, the drive will trigger alarm signals and execute safe stop actions to avoid equipment damage. The operating status and fault codes can be checked through the onboard display.

This compact high-performance drive is widely applied to light-duty industrial equipment. Typical applications include small conveyor lines, fans, water pumps, packaging machinery and small spindle drive units. It is suitable for occasions requiring stable speed regulation and basic positioning control. The built-in EMC filter simplifies on-site installation and wiring, and the standard version with uncoated PCB is applicable to common dry and clean indoor industrial environments.

This product has passed CE, UL 508C, CSA and RoHS certifications. It fully complies with industrial standards EN 61800-3 for electromagnetic compatibility and EN 60204-1 for electrical safety of machinery.

Compared with the 0T version of the same model, this 00 standard version uses uncoated PCB and only retains basic motion control functions. The 0T version is fitted with conformal coated PCB suitable for humid and corrosive environments, and supports extended functions such as electronic cam and synchronous control. Users can select the appropriate version according to actual on-site environment and functional requirements.
