SEW MPX22A-DFC20A-MPI-0070-5E3-CA-C Inverter 7.0A 3kW PROFINET IP65

SEW-EURODRIVE MPX22A-DFC20A-MPI-0070-5E3-CA-C Decentralized Inverter

MPX22A-DFC20A-MPI-0070-5E3-CA-C is a decentralized field-mounted inverter from the SEW-EURODRIVE MOVIPRO® technology series. It delivers 7.0 A / 3.0 kW in Size 2, and the DFC20A version uses PROFINET IO. Because the CA variant has no MOVILINK DDI motor interface, it relies on a standard motor connection. Moreover, it supports U/f, VFCplus, CFC, and ELSM control modes. As a result, it works with SEW synchronous motors, asynchronous motors, and third-party motors.

This unit is built for IP65 field mounting, so it needs no cabinet. In addition, it offers encoder evaluation for sin/cos, TTL/HTL, RS422, and HIPERFACE signals. It also includes up to 12 digital inputs, 8 digital outputs, 1 relay, 2 analog inputs, and 2 analog outputs. Furthermore, brake control options include DC 24 V (BMV5), AC 230-460 V (BD1B), and safe brake (SBM). Therefore, the fanless design up to 24 A suits tight spaces.

Technical Specifications

Key Features and Advantages

• Decentralized design removes the need for a central cabinet. It saves floor space and reduces cabling.
• PROFINET IO connects directly to the fieldbus. This lowers wiring effort and improves response time.
• IP65 protection allows field mounting in harsh environments. No extra enclosure is needed.
• Flexible motor support covers SEW motors and third-party motors. This cuts spare part variety.
• Fanless operation up to 24 A reduces maintenance and extends service life.
• Integrated C2 EMC filter meets EMC requirements without external filters.
• Safety options include PROFIsafe, CIP Safety, and Safety over EtherCAT. These support safe motion and safe position functions.
• Wide temperature range from -25 to +60 °C with derating. It fits cold storage and outdoor applications.

Installation Guide

Mount the inverter directly on the machine frame or wall. Use the IP65 rating to install in wet or dusty areas. Keep the unit vertical for proper heat dissipation. Connect PROFINET IO with M12 4-pin D-coded cables. Use the built-in C2 EMC filter for supply voltage 3 x AC 380-500 V. Wire the brake control (BMV5, BD1B, or SBM) according to the manual. The fanless design needs no extra airflow clearance. Confirm the operating temperature stays within -25 to +40 °C for full load. Add derating above +40 °C.

Commissioning and Maintenance

Set control mode (U/f, VFCplus, CFC, or ELSM) with the SEW startup software. Use the encoder evaluation for sin/cos, TTL/HTL, RS422, or HIPERFACE signals. The fanless design requires no fan filter cleaning. Check connections and heat sink annually. The IP65 protection means no dust or water ingress. Use the diagnostic functions to monitor DC link voltage and output current. The unit stores error codes for fast troubleshooting.

Compatibility Notes

This inverter works with SEW synchronous and asynchronous motors. It also supports third-party motors with encoder feedback. The CA variant uses a standard motor connection without MOVILINK DDI. Use PROFINET IO for direct fieldbus communication. Other DFC variants are available: DFC1 for EtherCAT/SBusPLUS and DFC3 for EtherNet/IP + Modbus TCP. Safety modules include CSB31A (basic safety), CSS.1A (extended safety motion), and CSA31A (safe position).

Diagnostic Capabilities

The unit provides DC link voltage monitoring. It tracks output current and PWM frequency. Error codes help identify faults fast. Use the PROFINET IO connection for remote diagnostics. The SEW startup software reads parameter settings and fault history. Safety diagnostics are available with MOVISAFE options.

Typical Applications

• Conveyor systems in automotive and logistics
• Packaging machines with decentralized layout
• Material handling in cold storage (down to -25 °C)
• Food and beverage lines with IP65 washdown
• Airport baggage handling with PROFINET IO
• Automated guided vehicles (AGVs)
• Retrofit of obsolete control systems
