The UD55 Cloning Small Option Module can store up to eight parameters-sets which contain all the read–write parameters for a Drive, and include those in Menus 16 & 20, when applicable. These parameter sets can be individually recalled for loading onto the same or another drive.
The cloning of drives can only be performed when the operating mode (Open-loop, Closed-loop Vector, Servo or Regen) of the destination drive is the same as that of the source drive. The UD55 must be fitted in the small option module bay of the Unidrive. All connections to the drive are made by a multi-way connector. Connections from external equipment are made to a plug-in 16-way screw-terminal block on the option module. Some parameters have a profound effect on the operation of the Unidrive. They must not be altered without careful consideration of the impact on the controlled system. Measures must be taken to prevent unwanted changes due to error or tampering.
1. Disconnect the AC supply from the Drive.
2. Check that the exterior of the UD55 is not damaged, and that the multi-way connector is free from dirt and debris. Do not fit a damaged or dirty UD55 in a Unidrive.
3. Remove the terminal cover from the Drive.
4. If a small option module is already fitted in the Unidrive, grip the recesses at the ends of the module and pull the module out of the Drive. Keep the module for re-fitting.
5. Position the multi-way connector on the rear of the UD55 over the connector in the Drive (see figure below), and press on the thumb pad to push the UD55 into place.
If the Drive trips and a trip code is displayed while this procedure is being followed, ensure that all the required parameters have been set up in the source Drive and that new parameter values have been saved.
If a small option module was fitted in the Drive, its associated Menu 16 parameters will be copied to the UD55 in addition to the parameters in the other menus. 1. Insert the UD55 in the source Drive (refer to Chapter 3, Inserting theUD55 in a Drive). 2. Ensure terminal 30 of the Drive Signal connector is open-circuit so that the Drive does not become enabled when powered-up. 3. On the UD55 connector, connect terminal 40 directly to terminal 41 to enable the save function (see Figure 2). 4. Re-fit the terminal cover to the Drive. 5. Connect the AC supply to the Drive. 6. Decide which parameter-set number is to be used in the UD55. If a parameter-set already contains parameter values, these will be over-written without warning. It is recommended that a record is made of at least the following for each parameter-set number:
• A means of identifying the configuration of the source Drive
• The model size of the source Drive
• The type(s) of option module(s) fitted
• Motor ratings 7. Set parameter .00 (in any menu) at 300X, where X is the required parameter-set number (1 to 8). 8. Press . The parameter values are now copied (saved) to the UD55.
Saving takes approximately 5 seconds. When it has finished, parameter .00 returns to zero. 9. It is recommended that parameter 11.38 is set at the number of the parameter-set (value of X in step 7) and the value of parameter 11.40 UD55 full parameter check sum noted, as a means of identifying the parameter-set at a later date. 10. Disconnect the AC supply from the Drive. 11. Remove the terminal cover. 12. Disconnect the link between terminals 40 and 41 on the UD55 connector. 13. Remove the UD55 from the Drive. 14. If a small option module was previously fitted in the Drive, re-fit the module. 15. Replace the terminal cover. 16. The Drive can now be used.

Maintaining and upgrading legacy systems is one of the most difficult challenges industrial and manufacturing managers face today. Constant technological change often weakens the business value of legacy systems, which have been developed over the years through huge investments. Managers struggle with the problem of modernizing these systems while keeping their functionality intact. Despite their obsolescence, legacy systems continue to provide a competitive advantage through supporting unique industrial processes. Routine checks allow for preventative maintenance, and for replacement parts to be ordered before they are desperately needed. Here at MRO Electric and Supply, we stock a large number of classic and legacy products which can be shipped in record time.
Legacy Systems: IoT
When new technologies arise, engineers simply cannot uproot existing systems. However, some legacy controls can be connected to the Internet of Things. This allows for a high level of data acquisition which can be stored, processed, and analyzed. Several IoT products can also support remote monitoring and control. Many Modicon Quantum Series products have an Ethernet port that allows for this upgraded connectivity. However, not every legacy system has these capabilities.
Legacy Systems: Security
Targeted attacks on industrial systems always remain a threat as our society plows forward into the computer-driven Information Age. Securing legacy systems that were designed to communicate point to point is a enormous challenge. Many of these older systems were installed pre-internet era, are not designed for connectivity, and have no means of authenticated commands that are received. System interruptions for security updates can be difficult and costly, and downtime is expensive. It is always a challenge to find ways to increase security for legacy systems. One important tip is to always keep the software for connected legacy systems updated with the most current version.
Legacy Systems: Looking Forward
Although replacement supplies and remanufactured parts can be ordered for many years to come, it is important to keep in mind that no legacy system will last forever. In this current sluggish world economy, often the best answer is a well-planned, slow and steady upgrade.
If you need a replacement part for any of your industrial classic or legacy systems, please email sales@MROElectric.com or call 1-800-691-8511.
The UNI3404 is available with a number of option modules, which increase its flexibility and make it suitable for a very wide range of applications. These modules are briefly described in the following paragraphs. For full details refer to UNI3404 manual that is supplied with each of them. The modules are in two physical formats and are known as Large Option Modules (LOM) and Small Option Modules (SOM). Each Undrive may be fitted with one LOM and one SOM.
Unidrive UNI3404 Large Option Modules
UD78 High Precision Analog Input Module. (LOM):
This module provides the following features: a) Infinite resolution analog input for precision speed and position control. Large Option Module Small Option Module 1.

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.
You can check out our previous blog post on the UNI2403 manual and UNI2403-r manual here with additional setup info. To get a UNI2403 price quote or for ordering info you can call 1-800-691-8511 or email firstname.lastname@example.org.
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.
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.

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 firstname.lastname@example.org or call 1-800-691-8511. We have these and all the other Unidrive Classic option modules in stock, along with the drives themselves.
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.
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 email@example.com or call 1-800-691-8511.
The table below shows a quick reference for all of the different option modules that can be used with the Unidrive Classic series. We have all of the different modules available and in stock.
On Unidrive Classics, when a UD7x Unidrive option module error trip occurs,
the display will show the trip code as “tr__”. The trip number
can also be read in Unidrive parameter #10.20 or UD70
virtual parameter #88.01, and the line number where the trip
occurs in parameter #17.03, though only if the program was
compiled with debugging information.
When an error occurs in the UD70, the DPL program will
immediately stop. Also, depending on the cause of the trip
and the setting of the Trip enable parameters, the Unidrive will
trip on the “tr__” code. Optionally, an ERROR task may have
been defined which would be executed whenever a run-time
error occurs. MRO Electric and Supply maintains a comprehensive stock of new and used Control Techniques Unidrive and Control Techniques Unidrive Classic SP parts. If you need a replacement part, please call 800-691-8511 or email firstname.lastname@example.org.

*When a trip occurs, all tasks of the DPL program will be halted (real-time tasks will
first complete) and any ERROR task is executed. The only exception to this is with trip 45, trip
52, trip 60 with certain option cards, the Watchdog trip (Prc2) and any other normal drive trips.
The line number is only available when the program was compiled with debugging information.
Any other trip numbers that appear are either generated by the drive itself or the DPL program.
