Emotron VFX 2.0 AC Drive

Features:

Crane control A crane I/O expansion board offers efficient riding, lifting, and speed control, and a safety system that activates the mechanical brakes should dangerous loads be detected.Shorter braking timeFor extremely short braking time a brake chopper is available as a factory-installed option. It is used in combination with brake resistors dimensioned according to the specific application demand.Communication
Communication options include fieldbus communication via Profibus and DeviceNet, Industrial Ethernet communication via Modbus/TCP, EtherCAT and Profinet, and serial communication via RS232 or RS485 with Modbus RTU.

Motor protection

PTC and PT100 sensors can be connected to control motor temperature and give process feedback without using a transmitter.

Encoder

An encoder can be connected for more accurate speed control or for increased safety through deviation control in crane applications.

Safe stop

This option board offers protection from unexpected start during mechanical maintenance, in accordance to the EN-IEC 62061:2005. SIL3 & EH- ISO 13849-1:2006 Category 3 standard. No contactor is required.

EMC protection

EMC filter according to class C3 – 2nd environment included as standard in all drive units.

Reduced harmonic distortions

A 12-pulse rectifier offers a cost-efficient reduction of harmonic current distortions. It reduces power losses in equipment such as transformers and conductors, and eliminates the need to over-dimension these components.

Standby supply

Makes it possible to supply the control circuits via an external 24 V AC/DC supply to maintain communication and set up the system when 3-phase mains is not connected. Provides communication backup if 3-phase main power supply fails.

Emotron VFX 2.0 AC drive optimizes the operation of your cranes, crushers, mills and mixers. Your process is protected from damage and downtime and you will benefit from reduced installation, energy and maintenance costs. 'High dynamics for demanding applications'. Efficient and protective starts and stops Efficient and protective starts are ensured with Emotron VFX. Reduced start currents result in smaller fuses, cables and energy bills. Torque can be boosted to overcome initial peak loads. Integrated vector braking ensures quick and controlled stops, increasing productivity and safety. Optimized operation and full control The direct torque control reacts extremely quickly and eliminates disturbances due to abrupt load changes. A built-in shaft power monitor and a unique Load Curve Protection function protect your process by immediately detecting any situation that could cause inefficiency or damage. Early warnings and safety stops allow preventive action. User-friendly and reliable operation. Operation parameters can be set in your own process units – m/sec, tons/hour, cycles/min etc. – making monitoring easier and more reliable. The removable control panel has a copy function for transferring settings to other Emotron VFX units. You can switch between local and remote control by the push of a key on the control panel. The virtual connection of logical functions, comparators and timers means no cables or external I/Os are required. Available in IP20/21 and IP54 versions Emotron VFX is available in IP20/21and IP54 versions. The robust steel construction in IP54 version means that you can install your AC drive close to the application, which saves the cost of cabinets and long motor cables.The 300-1,500 A units (IP20 modules) is also available in compact CG-designed IP54 cabinets. IP20/21 series 25-365 A are optimized for mounting in control cabinets (IP20) or on electrical room wall (IP21). Robust and compact design, easy access to power terminals. Extended temperature range up to 55 °C. Simplified maintenance Should a process problem occur a full status report will be generated. You can quickly identify the cause and take corrective measures. Maintenance is simplified thanks to a minimum of easy accessible mechanical parts and fold-out power modules.
