UNI2403 Configuration and Setup

The UNI2403 and UNI2403-r configuration process is a relatively simple setup process that should be able to get you back up and running with minimal downtime.

With some simple UNI2403 11kw configuration the drive can be used as an AC Regenerative Unit, also known as a Regen Drive. In the case of a drive operating in Regen mode, the IGBT bridge is used as a sinusoidal rectifier, which converts the AC supply to a controlled DC voltage. This DC voltage can then be used to supply one or more Unidrives which control motors, commonly known as motoring drives.

A regen drive produces PWM output voltage which has a sinusoidal fundamental at an amplitude and phase which are almost the same as those of the AC supply voltage. The difference between the drive PWM line voltage and the supply voltage occurs across the Regen drive’s inductors.

There are a number of possible options available when designing a Unidrive Regen system depending on the user requirements and the nature of the AC supply. Non standard systems can be created where favourable supply conditions exist, allowing cost and space savings to be achieved by reducing the number of components.

A Unidrive can be used as a sinusoidal input current power unit to supply one or more Unidrives via their DC buses. When this mode is selected as the drive type, menu 15 appears. This menu is used to set up the Unidrive. At the same time, menu 0 defaults to showing Pr 15.01 to Pr 15.13 as Pr0.11 to Pr 0.28.

UNI3405: Beyond the User Manual Parameters

The UNI3405 Unidrive is part of the Classic Unidrive series. Control Techniques introduced the Unidrive Classic around 1993 in Europe and approximately 1995 in the Americas. Because the Unidrive Classic ran simple Open Loop, Closed Loop Vector, and Servo motor applications as well as offering a Regen mode, the UNI3405 found its way into a great many industrial applications, from simple to quote complex. Visit our website to checkout all of our Control Techniques products.

Due to its status as a legacy product, the UNI3405 is becoming available only in limited quantities.

The UNI3405 contains approximately 500-600 parameters that help machine manufacturers achieve the desired functionality for a certain machine requirement. Some applications may require 20-30 or more parameters to be changed from the drives factory default settings. Should drive replacement become necessary, one must have a complete and accurate list of these parameters so that the original functionality can be restored. If you do not have a list of the required parameters, one could copy down these parameters manual. This is assuming that the drive still works enough to power the display, and even then the manual copying of parameters is tedious and error prone.

UD75: Beyond the User Manual

The UD75 CTnet Interface card for the Unidrive Classic series is supplied in a large option module. It is an add-on card for the UD70 applications card. The UD70 processor and operating system handles all network activity, and uses a dual-port RAM interface to transfer data between itself and the drive.

The UD70 CTnet retains full functionality, allowing the user to download normal DPL application programs. No program modifications are required to allow existing DPL programs to run. A different UD70 operating system file (“UD70NET.SYS”) is used, and the UD70 has this system file pre-loaded.

The Unidrive must be disconnected from the mains supply before installing or removing any option module, including the UD75.

Isolate the drive from the mains supply and allow 5 minute for the DC bus capacitors to discharge. Insert the large option module. Ensure that it is correctly inserted. The module will click firmly into place. To remove the module, pull on the black tab and the module will disengage from the connector and pull out of the drive.

For more info you can visit the UD75 product page here. For price and ordering info you can email sales@mroelectric.com or call 1-800-691-8511. We have these and all the other Unidrive Classic option modules in stock, along with the drives themselves.

UNI1405 Manual Installation and Pricing

The Control Techniques UNI1405 Unidrive is a 5hp, 9.5A AC drive with a peak output of 9.6kHz. All of the Unidrives have a built-in encoder port which is ready to accept motor rotational feedback after installation. There are three option modules available to compliment or extend the range of motor speed / position feedback capabilities.  For additional info about the UNI1405 manual programming of the option modules you can check out our post about the UD73 option module here.

Each of these option modules creates a simulated encoder output as either line driven quadrature channels or as frequency / direction signals to facilitate follower applications.

UD73 Module: Beyond the Manual

The Control Techniques UD73 large option module is a high speed microprocessor that provide a low cost facility for a system designer to write app specific programs without needing a PLC or other stand-alone controllers. The module is programmed via the RS232 port using the Control Techniques system programming toolkit.

The UD73 module uses a dual port RAM to interface to the drive’s main processor which provides intimate high-speed bi-directional access. It can ready and modify any of the parameters within the drive. This enables customized real-time calculations under a multi-tasking run-time environment.

The optically isolated RS485 port serves as a communication for for the CTIU operator interface units. It is fully configurable, supporting many communication modes. In addition, the module has the Profibus-DP port for additional communication options.

For additional info you can visit the UD73 product page on our website here. We will continue to post info about the Control Technique option modules in the future. If you would like to order a module or get more info you can email sales@mroelectric.com or call 1-800-691-8511.
