During the 140CPU53414B firmware configuration, there are two switches (a three-position slide switch and a three-position key switch) and one connector (Modbus RS-232) located on the front of the CPU.

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.

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.
Simodrive F-16 Alarm Code Troubleshooting & Diagnostics
We recently had a customer install a replacement 6SN1121-0BA11-0AA1 card into a 6SN1123-1AA00-0EA1 power module. When they installed the card it came up with an F-16 alarm code on the display of it, which references an “Illegal Power Module.” Using the instructions in the manual for the start-up of a replacement Simodrive card or power module we were able to get the customer back up and running with the steps below.
