New CEO

Wed, 06 Mar 2013 14:26:15 GMT

As CEO Samuelsson will be globally responsible for the Drives & Automation product area. Samuelsson's latest employer was Tetra Pak where he held various managerial roles during a 10 year period, finishing up as “Director Automation Solutions”. He had global responsibility for product and business development of automation solutions and operative responsibility for organisations in Sweden, Italy and India. Previously, Samuelsson has many years experience of executive market and sales positions at ABB and Alfa Laval.

- CG Drives & Automation is an exciting company with great opportunities,” says Mikael Samuelsson. “As a part of Crompton Greaves, and in collaboration with a strong team and motivated staff, I see great development and growth potential.”

Clean water with flexible communication

Fri, 15 Mar 2013 11:38:53 GMT

Prästjorden’s Water Station in Halmstad is one of the 17 water stations supplying Halmstad with drinking water. The water station pumps up 80 cubic meters of water every hour from a depth of 40 meters. The water goes directly into Halmstad’s drinking water without any cleaning at all. All that is added is some sodium in order to raise the water’s pH. However, given the large amounts of water, the sodium adding can be a time-consuming task. Magnus Winberg, coordinator at Halmstad Municipality explains: “Previously, we had to manually add nine bags of sodium each day. The new pump system handles this automatically which saves us a lot of work.”

Prästjorden’s Water Station, Halmstad. Through the pipe in Prästjorden’s Water Station, 80 cubic meters are pumped up every hour.

CG Drives & Automation’s products control the pumps

Halmstad’s water system use approximately 200 soft starters from CG Drives & Automation, making the pumps start and stop smoothly to minimize wear. In addition, 60 drives are used to set the exact engine speed for the pumps. The drives generate substantial power savings since it is possible to set the pump’s revolutions per minute (RPM) instead of running the engine at full speed and throttle the water flow.

Anybus CompactCom converts the signals from the network in the water station (in this case, Modbus-TCP) and make these signals understandable for the drives and soft starters used to contol the pumps.

Easy networking as well

The 17 pump stations in Halmstad are controlled by different industrial networks. To communicate with these, CG’s drives are delivered with an Anybus module from HMS. This pluggable communication module enables CG’s drives and soft starters to communicate with many different networks. Prästjorden’s Water Station, for example, use both Modbus- TCP and PROFIBUS to control the different pumps. “The communication modules enable us to connect our products to several different networks,” says Lars-Olof Pejner, who is CG Drives & Automation’s account manager for Halmstad Municipality. “The communication modules also make it easier for the system integrators when installing the products in the electrical cabinets.”

New Softstarter

Mon, 26 Nov 2012 09:19:19 GMT

Features included in the new series:

Integrated by-pass.
3-phase torque control.
Coated boards.
Multilingual LCD display.
Programmable logical and timer functions.
Real Time Clock.
Motor load monitor with alarm level auto-set.
Controlled braking capability.
Slow speed and jog operation.

Emotron TSA fits where space is limited due to its integrated by-pass contactors.

The first frame sizes introduced suits motors with up to 100 A rated current but units up to 1,800 A will be available. Voltage classes include 200 – 525 V and 200 - 690 V.

New AC-drive

Mon, 26 Nov 2012 09:18:37 GMT

A robust mechanical design, easy access to connection terminals and a high level of component integration have been key objectives in the development and the new series includes standard features like:

Direct torque control for accurate and fast control (Emotron VFX).
Dedicated pump and fan control.
Programmable logical functions including comparators and timers
Motor load monitor with alarm level auto-set
Multi-lingual control panel with single-function keys and copy function
Built-in DC-choke for reduced harmonics and maximum voltage utilisation.
Integrated EMC filter Category C3.
Speed controlled fan in all powers for extended equipment lifetime.

The IP20/21 series of drives are optimised for mounting in electrical cabinets (IP20) or directly on a control room wall (IP21) and cover powers up to 132 kW. For decentralised applications and harsh environment though, the company recommends their IP54 units of the same series.

Profinet

Fri, 25 May 2012 12:14:02 GMT

Profinet IO offers fast real time industrial Ethernet communication for Emotron FDU/VFX AC drives. Standard TCP/IP traffic can continue to flow in the network in parallel. This opens up for vertical integration of production to ERP and MES systems, or access to a built-in web server for simple diagnostics and parameter settings.

By using the Profinet IO option in combination with managed switches supporting MRP or MRRT protocols, you can implement very robust LANs with redundant information paths. Reliability is improved since the process can continue also if one Ethernet cable is damaged.

The option is available as 1-port and 2-port versions. Both versions include the Profinet Fast Start Up feature, which allows a machine to quickly come into operation at power on. The 2-port module also supports LLDP and SNMP protocols, which can significantly improve diagnostic information and cut downtime in the case of a communication fault. Further, the 2-port module has a built-in switch for easy daisy-chaining between units.

The AC drive is controlled by a simple I/O data control/status message, which can be customized to your application. The option is delivered with a CD containing Simatic Step7 PLC code examples for a quick implementation.

AC drives in new CG costume

Tue, 31 Jan 2012 10:03:54 GMT

Emotron is now CG Drives & Automation, and part of the global company CG. As a consequence, we are introducing our products in a new costume. This will have no practical effect for you as a customer. You will be buying the same product, developed and produced in Sweden, with the same functionality, the same hardware/software and the same operator interface – just with a new appearance.

The CG design will first be introduced on our Emotron FDU/VFX AC drives in February. Next in line will be our softstarters Emotron MSF in March, and in April-May our monitors Emotron M20/DCM. All products will be changed by 31 December 2012.

See the new looks of our Emotron FDU/VFX AC drives below!

EtherCAT for Emotron AC drives

Tue, 22 Nov 2011 15:13:26 GMT

A new EtherCAT option board provides Emotron FDU/VFX AC drives with a very fast industrial Ethernet interface in combination with a high level of reliability. All AC drive parameters can be accessed via the network using the CoE (CANopen over EtherCAT) application protocol. This makes it possible to easily control, monitor, adjust and configure the drive.

EtherCAT is an open industrial protocol which has been developed with focus on time critical applications, using the available bandwidth in a very efficient way. This is achieved through the protocol implementation as well as a fast integrated ASIC in every node, removing the need and cost for external switches. The ASIC takes care of the process data exchange “on the fly”, which minimizes the telegram delay in each node, creating a very rapid bus system.

The EtherCAT network topology is very robust, since it forms a “virtual ring” by using both pairs in an Ethernet cable. Using a PLC with two Ethernet ports allows you to create an even more robust redundant ring network.

The specification of the protocol is maintained and developed by EtherCAT Technology Group (ETG) and its members.
