Rosenberg Modbus Gen2/3

One of the big cleanroom players in the US planned to use Rosenberg EC-fans for its FFUs for a cleanroom project. So our task was to create a firmware update for our EC-Fan Control device uniqunet to control exactly these fans. As the handling of the reading- and writing-register of the Rosenberg Modbus is kind of tricky it was a bit of a challenge to get this integrated inside the package-commanding structure of the uniqunet control device.

At the end there is besides some compliments from the costumer an appealing hardware order, of course including the new firmware.

At the Green Island – Control Devices for EC-Fans

The Green Island was up to now a black spot at our. This is now to be changed. The biggest distributor of ebmpapst in Ireland requires on of our EC-Control devices a customer.

The handtool of uniquom series should control EC-fans with ebmBUS- and Modbus-Interface, but especially whole parameter sets of Modbus fans should be cloned. Therefore the vbk.cmd Clone Master is the right platform to save whole data sets individually for each project before sending out the ec-fans to customers’ site.

MODBus-RTU-DCI vs. MODBus-RTU

to stay deliverable, on of our cleanroom customers decided somewhat unsuspectingly to apply the DCI-Variation, instead of the normal MODBus-RTU variation of his EC- FFU s from ebmpapst. As consequence some single commands of the "Install fan"- order package of our FFU-control device uniqunet ended in nowhere, that the installation process could not be accomplished. Even if not caused by us a software adaption of the uniqunet control device seemed to be the most simplest solution.

Seven days, incl. basic investigation, program adaption, test, verification and application at customers’ side is more than presentable, as we do think.

Cleanrooms – Modernization of an ebmpapst Control

Following a recommendation by ebmpapst a big building automation company from Leipzig requested support for renewing a FFU control system of EC-FFUs, each with an ebmpast-drive, in Erfurt.

With pleasure we provided, besides to some advices, a handheld tool for the EX-Fans free of charge to check the operation of the system. As only the terminal-box has been changed to one with ebmBUS interface, it was not entirely clear if a surprise awaited the costumer.

Yesterday evening we received the enjoyable feedback, anything went perfect and that easy that they even had enough time to address the FFUs already correctly. So there are no technical reasons that speak against the usage of 3 EC-FFU Control devices.

EC Motor Control for US-Cleanrooms

By mid of March a US-American OEM-customer placed an order for controllers for their EC fans. Hand programming tools as well as EC Control devices for the fixed installation were ordered to use the ec fan advantages of their ec fan technology in cleanroom applications.

It is for us more than a matter of decency, even in difficult times, to match costumers’ wishes in terms of delivery date. Due to the outstanding commitment of our employees we achieved to create a time reserve the American duty know “to use”.

… this time no "ec motor control"
