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.

Since capacitance in the motor cable causes loading on the output of the UNI3405 Drive, ensure the cable length does not exceed 660 ft. (400 volts) or 410 ft. (480 volts).
Cable lengths in excess of the specified values may be used in the UNI3405 configuration only when special techniques are adopted; refer to the supplier of the Drive.
The maximum cable length for the Unidrive UNI3405 configuration is reduced from that shown above under the following conditions:
PWM switching frequency exceeding 3kHz in model sizes 3 and 4 — The maximum cable length is reduced in proportion to the increase in PWM switching frequency, eg. at 9kHz, the maximum length is 1/3 of that shown.
High-capacitance cables – Most cables have an insulating jacket between the cores and the armour or shield; these cables have a low capacitance and are recommended. Cables that do not have an insulating jacket tend to have high capacitance; if a cable of this type is used, the maximum cable length is half that quoted in the table.
The Drive has two forms of thermal protection for the power output stage (IGBT bridge), as follows:
A thermistor mounted on the heatsink monitors the heatsink temperature. If this exceeds 95 °C (203 °F), the thermistor will cause the Drive to trip. The display will indicate Oh2
Intelligent thermal modelling estimates (by calculation) the junction temperature of the IGBTs. There are two temperature thresholds which cause the following to occur:
If the first threshold is reached, the PWM switching frequency is halved in order to reduce dissipation in the IGBTs. (When the frequency is halved, the value of parameter 0.41 PWM switching frequency remains at the value set by the user; if the frequency is 3kHz or 4.5kHz, no halving occurs). Then at one second intervals, the Drive will attempt to restore the original PWM switching frequency. This will be successful if the estimated temperature has reduced sufficiently.
If the estimated temperature has continued to rise and reaches a second threshold, the Drive will trip. The display will indicate Oh1.
You can check out our previous blog post on the UD73 here for additional setup and configuration info.
For UD73 configuration, most common parameters are arranged in one concise menu. Hundreds of user-configurable functions separated into 20 logical menus provide quick setup for advanced application. For positioning, ratio control, camming and multi-axis systems, plug-in option modules easily extend the Unidrive’s capabilities. High horsepower Unidrives cover the range from 200 to 1600 HP. The 300 amp power module and control pod (the “brain”) are available as components. They are also available as a packaged drive solution that includes fusing and a disconnect. (See our Packaged Drive Section, pages 120-123 and 128-133.) With the UD73’s extensive selection of communication, application, feedback and I/O modules, you can easily upgrade the performance of your drive. Yet, it is simple to configure by using the drive keypad, a remote keypad (CTKP), or UniSoft, the UD73 Windows based drive set-up tool. You can tailor each Unidrive to be the drive you want when you want it.

The UD73 configuration is suited for use with AC brushless servo motors. Servo control is ideal for applications requiring load transfer to and from any position, at any speed. The UD73 is designed for both stand-alone and multi-axis system applications.
In regen mode, two standard UD73’s operate together to provide full four-quadrant control of an AC motor. The system consists of two basic sub-systems, one being a Unidrive operating in any of its standard operating modes (open loop, vector or servo), and the other is a Unidrive operating in its regenerative mode. The link between the two sub-systems is simply the DC bus connections. In this mode, the UD73 is capable
of either supplying power to the DC bus of the Unidrive controlling the motor or removing power from the DC bus of the Unidrive controlling the motor and returning it back to the power line.

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.

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 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 UNI2403 Unidrive is a size 2 Unidrive with 5.5kW, 10HP, a 25A output and 19.8A input. The versatile Unidrive was the first universal AC drive capable of providing V/Hz, open, and closed loop vector, servo, and regen control in every unit. The unidrive combines all five of these AC drive technologies into one for the ease of the customer.
For quick setup of basic applications, the UNI2403’s most common parameters are arrange in one main menu. There are hundreds of user-configurable functions that are separated into 20 logicial menus which provides quick setup for advanced apps.
The Control Techniques Commander SK series contains several levels of security. The level 1 security set has parameters from 1 – 10. These parameters are the most basic drive configuration registers, containing mostly motor information and start/stop selections. Level 2 allows you to view and modify parameters 1 – 60. These include more advanced features, such as, the brake control and fieldbus configuration. Level 3 access is used to access parameter 1 – 95. Parameters 61 – 80 in this level can be used to gain access to any register in the drive. Within level 3 you are also able to gain access to the diagnostic functions of Pr 81 – Pr 95. The last level is a custom security setting called Loc which can be used to edit any registers in the drive.
The Control Techniques Focus 3 drive is a single-phase analog drive for DC motors. The Focus 3 provides anywhere from ¼ to 5 horsepower and has 2 regenerative and 2 non-regenerative chassis units. Several measures can be taken to keep your drive functioning its best:
Be sure to keep your drive free of dust, dirt, oil, caustic atmosphere and excessive moisture.
The control should always be set away from any machines that have a high ambient temperature.
Air flow should not be restricted by other equipment.
Keep the drive away from high vibration areas that could cause the connections to loosen or chafe the wires.
