The Emotron FDU 2.0 is an AC drive designed for controlling and protecting pump and fan applications that demand high levels of flow control, process uptime, and low maintenance. It can also be used for compressors and blowers, utilizing V/Hz-control as its motor control method.

Function Description

The Emotron FDU 2.0 is a variable speed drive (VSD) suitable for use with standard 3-phase asynchronous motors. It offers a range of functionalities to optimize motor control and protection. The drive can be customized with various options, including different EMC filters, brake chopper options, standby power supply, and safe stop features, as indicated by its type code number.

Key functional areas include:

Motor Control: Employs V/Hz-control for efficient operation of asynchronous motors.
Application-Specific Control: Features dedicated functions for pumps and fans, including pump control (e.g., fixed MASTER, alternating MASTER, feedback 'Status' input, fail-safe operation, PID control) and fan control.
Load Monitoring and Process Protection: Incorporates advanced load monitoring [400] and process protection [420] features to safeguard the motor and application.
Parameter Sets: Supports multiple parameter sets (one motor and one parameter set, one motor and two parameter sets, two motors and two parameter sets) for flexible configuration and quick changes between operating modes.
Autoreset at Trip: Allows for automatic restart of the motor after a trip, provided the cause of the trip has been removed.
Reference Management: Offers reference priority settings, preset references, and remote control functions for precise speed and torque control.
Identification Run: Enables an identification run to optimize motor parameters for improved performance.
I/Os and Virtual Connections: Provides extensive input/output capabilities, including analogue inputs, digital inputs, analogue outputs, digital outputs, relays, and virtual connections for flexible integration into control systems.
Logical Functions and Timers: Includes comparators, logic outputs, and timers for implementing custom control logic.
Serial Communication: Supports Modbus RTU and other fieldbus options for integration into larger automation systems.

Important Technical Specifications

Mains Voltage Selection: Available in different voltage ranges:
- FDU48: 230-480 V
- FDU52: 440-525 V
- FDU69: 500-690 V
EMC Compliance:
- Complies with EN(IEC)61800-3:2004, designed to meet Category C3 requirements.
- Optional "Extended EMC" filter allows compliance with Category C2 for use in domestic environments.
- Earth Leakage Current: Exceeds 3.5 mA AC, requiring protective earth conductor sizing in accordance with IEC61800-5-1.

Cooling: Designed for vertical mounting. Minimum free space around the AC drive is required for adequate cooling, with specific distances for different models (003 to 3K0). Airflow rates for cabinet-mounted units vary by FDU model, ranging from 75 m³/hour (B 003-018) to 12000 m³/hour (T69 3K0).
Protection Class: Available in IP20 and IP54.
Rated Current: Varies significantly by model, from 003 (2.5 A) up to 3K0 (3000 A).
Software Version: Instruction manual covers software version 4.3X.

Usage Features

Control Panel: Features a user-friendly control panel for operation, programming, and monitoring. The display provides indications, LED indicators offer quick status checks, and function keys facilitate navigation and parameter editing.
Handheld Control Panel (HCP): An optional handheld control panel (EmoSoftCom) provides remote access and configuration capabilities.
Menu Structure: Organized menu structure (Main Setup, Process and Application Parameters, I/Os and Virtual Connections, Logical Functions and Timers, View Operation/Status, View Trip Log, System Data) allows for easy access to various settings.
Programming: Parameters can be programmed during operation, and values can be edited directly in menus. The ability to copy current parameters to all sets simplifies configuration.
Quick Setup Card: A quick setup card can be placed in a cabinet door for easy access to essential information in emergencies.
Motor Data: Comprehensive motor data settings (e.g., nominal motor current, power, torque, frequency, speed) allow for precise motor matching and control.
Motor Protection: Includes various motor protection features to prevent damage.

Maintenance Features

Troubleshooting and Diagnoses: The manual provides extensive information on trips, warnings, limits, and their causes, along with remedial actions.
Trip Log: A trip log [800] records trip messages [810] and allows for resetting the log [8AO].
Opening the AC Drive: Specific instructions and warnings are provided for opening the AC drive, emphasizing the need to switch off mains voltage and wait at least 7 minutes for buffer capacitors to discharge to avoid dangerous residual DC-link voltage.
Cabinet Mounting: For cabinet-mounted units, a recommended free space of 1.30 meters in front of the cabinet is advised to allow for removal and replacement of PEBB modules.
Transport: Original packaging should be used during transport to prevent damage.
Condensation: If moved from a cold to a warm room, condensation may occur. The mains voltage should not be connected until all visible dampness has evaporated.
Dismantling and Scrapping: Detailed instructions are provided for the disposal and recycling of components, emphasizing compliance with local and national regulations, especially for electrolytic capacitors and circuit boards containing tin and lead. The product is marked with the WEEE symbol, indicating it should be taken to a collection point for recycling electrical and electronic equipment.
