Emotron VFX 2.0 variable speed drive – options that add functionality

Emotron – start, protect, control and stop processes driven by electrical motors

Options add functionality

A number of options let you customize the Emotron VFX 2.0 functionality and fully utilize the product according to your needs. Four different options can be combined.

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 time
For 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, 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.

Safety stop
This option card offers protection from unexpected start during mechanical maintenance, in accordance to the EN954-1 Category 3 standard. No contactor is required.

Liquid cooling
Units from 90 A can be provided with liquid cooling. This allows you to reduce operating and maintenance costs, and the cabinet can have a protection class higher than IP54.

EMC protection
A 1st environment category 2 EMC filter is available as a factory-mounted option.

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.
