Siemens 6SE6440-2UD31-1CA1

Micromaster 440 6SE64402UD311CA1

The Siemens 6SE64402UD311CA1, part of the Micromaster 440 (MM440) series, is a powerful and versatile AC frequency inverter designed to drive 3-phase motors with a power rating of 11 kW (equivalent to 15 horsepower). Engineered for precision and efficiency, this drive is a go-to solution for various industrial applications, offering reliable performance and robust control capabilities.

Operation

As a 3-phase drive, the 6SE64402UD311CA1 is well-suited for industrial setups that require continuous and stable power delivery. Its output current rating of 26A (for Current Transformers) or 32A (for Voltage Transformers) ensures consistent power flow to the connected motor, promoting smooth and efficient operation. The drive's capability to operate in either Constant V/F (Voltage/Frequency) mode or Sensorless Flux Vector control mode provides flexibility in matching the control strategy to the specific motor and application requirements.

This Siemens AC drive features an input voltage rating of 380-480V AC, making it compatible with a wide range of power supplies commonly found in industrial environments. The inclusion of both analog and digital inputs and outputs (2 analog inputs, 6 digital inputs, 2 analog outputs, and 3 relay outputs) offers versatile connectivity options, allowing for integration with various control systems and enabling precise control over the motor's performance.

Features

One notable feature of the 6SE64402UD311CA1 is its robust overload capabilities. It can handle high overload conditions, sustaining 150% of its rated current for up to 60 seconds, and even higher loads of 200% for 3 seconds, when operating at 11 kW in high overload mode. For applications where fan or pump operations are required, the drive can support an overload of 110% for 60 seconds or 140% for 3 seconds when running at 15 kW. This level of overload protection ensures the drive's durability and reliability in demanding operating conditions.

The drive's speed control range spans from 0Hz to an impressive 650Hz, providing the flexibility to accommodate a wide variety of motor speed requirements. For applications where controlled deceleration or braking is necessary, the drive can be connected to an external braking resistor with a minimum resistance of 56 Ohms. This feature enhances safety and control, particularly in scenarios where rapid motor deceleration is crucial.

Installation

Installation and maintenance of the Siemens 6SE64402UD311CA1 are straightforward. The drive's compact design, with dimensions of 185mm wide, 245mm high, and 195mm deep, allows for versatile mounting options. It can be wall-mounted in a clean environment or placed in a cubicle, with specific ventilation requirements taken into account to ensure proper heat dissipation. The drive's operating temperature range of -10°C to +50°C makes it suitable for a variety of working environments. The Siemens 6SE64402UD311CA1 is compatible with various operator panels that can be purchased separately. These panels offer different levels of control and monitoring, catering to users' specific needs.
