SEW MC07B0040-5A3-4-00 4kW Inverter | MOVITRAC B Drive

SEW MC07B0040-5A3-4-00 AC Drive | 4kW 380-500V

Product Introduction

The SEW MC07B0040-5A3-4-00 is a robust frequency inverter engineered for industrial motor speed control. As part of the MOVITRAC® B family, this 4kW unit combines compact dimensions with advanced functionality. The drive supports three-phase 380-500VAC supply and provides a rated output current of 9.5A. Its integrated brake chopper enables four-quadrant operation, making it suitable for applications requiring rapid deceleration or holding torque. Furthermore, the built-in PROFINET interface (DFE32B) allows seamless integration into modern automation networks. The FSC11B communication module facilitates SBus connectivity and system diagnostics.

Technical Specifications

The MC07B0040-5A3-4-00 delivers reliable performance across a wide voltage range. Key electrical parameters include a nominal input of 3×AC 380-500V at 50/60Hz. Specifically, the output voltage spans from 0 to the line voltage. At 400VAC input, the rated mains current reaches 8.6A, while the 125% overload current sits at 10.7A. The recommended motor power is 4.0kW (5.4 HP) for both 100% and 125% duty cycles.

For dynamic braking requirements, the minimum permissible braking resistance measures 68Ω. The maximum output frequency extends to 599Hz, supporting high-speed spindle applications. Meanwhile, current limiting is set at 150% of nominal output current for at least 60 seconds. Terminal connections accommodate wire sizes up to 4mm² (AWG12) with a tightening torque of 0.6Nm.

Mechanical and Environmental Parameters

This SEW inverter features a compact form factor measuring 80mm (W) × 273.5mm (H) × 163.5mm (D). The size 0L chassis optimizes control cabinet space utilization. Natural convection cooling suffices for standard operation, though forced cooling at 18m³/h is available for demanding conditions. The unit weighs approximately 2.1 kg (4.6 lb).

Regarding environmental tolerance, the drive operates nominally up to 50°C ambient temperature. With current derating, operation extends to 60°C. The integrated line filter maintains Category C2 suppression levels per EN 55011, reducing electromagnetic interference concerns.

Installation Guidelines

Proper mounting ensures reliable long-term operation. First, select a vertical position within the cabinet to promote airflow across the heat sink. Next, maintain clearances around the unit per SEW specifications for adequate convection. The MC07B0040-5A3-4-00 supports wall-mount installation using the rear mounting holes.

Wiring procedures require attention to terminal assignments. The mains supply connects to L1, L2, and L3 terminals, while the motor attaches to U, V, and W outputs. Additionally, the brake resistor connects to the designated terminals when dynamic braking is needed. For PROFINET communication, install the DFE32B interface and configure the SBus address accordingly. Finally, verify parameter P881 is set correctly for network operation.
