The Micromaster 440 is a highly versatile and robust standard frequency converter (AC drive) from Siemens, designed for complex speed control applications in a wide range of industries. The specific model 2UD25-5CA0 defines its electrical characteristics and hardware configuration.

1. Key Product Identification

• Product Family: MICROMASTER 440 (MM440)

• Order Number / MLFB: 6SE6440-2UD25-5CA0

• Description: Variable Speed Drive, 3-Phase

2. Electrical Specifications

This specific model has the following key power ratings:

• Supply Voltage:

  • 3-Phase: 380 V to 480 V AC (±10%)

  • Supply Frequency: 47 Hz to 63 Hz

• Rated Output Power: 5.5 kW (approximately 7.5 HP)

• Rated Output Current: 12.5 A

• Output Frequency: 0 Hz to 650 Hz

3. Core Product Features & Capabilities

The MM440 is renowned for its flexibility and comprehensive feature set:

• Control Modes:

  • V/f Control: For applications without high dynamic requirements (e.g., pumps, fans, conveyors).

  • Sensorless Vector Control (SLVC): Provides high starting torque and better speed control without a feedback encoder.

  • Closed-Loop Vector Control (with encoder feedback): For the highest level of performance and precision, requiring an optional encoder module.

• Integrated Features:

  • PID Controller: Allows the drive to be used as a standalone closed-loop controller for processes like pressure, flow, or level control.

  • Programmable I/Os: Multiple digital and analog inputs/outputs that can be configured for various functions.

  • Built-in Brake Chopper: Essential for controlling motors that require rapid deceleration or are driving high-inertia loads. (Note: An external braking resistor must be purchased separately and connected).

• Advanced Technology Functions:

  • Flux Current Control (FCC): Improves motor efficiency and dynamic response.

  • Energy Savings Optimizer.

  • Programmable Fixed Speeds, Ramp-up/Ramp-down times.

  • Comprehensive protective functions (motor overtemperature, overvoltage, undervoltage, overload, etc.).

4. Communication Options

The MM440 is designed for easy integration into control systems. The -5CA0 suffix indicates the standard factory configuration, which typically includes:

• Built-in RS-485 (USS) Interface: Allows for simple serial communication with Siemens PLCs (like S7-200/1200/1500) or other devices using the USS protocol.

• Optional Fieldbus Boards: To connect to industrial networks like PROFIBUS DP, PROFINET, DeviceNet, or CANopen. These are installed on the dedicated slots on the control unit.
