SP7412 Control Techniques

Unidrive SP 160KW Inverter Drive 290A 380-480V AC Three Phase

The SP7412 is a 160kW, 250HP, 290A, Three Phase 380-480V AC VSD from the Unidrive SP range manufactured by Control Techniques. With years of experience working on Control Techniques products, AFi Systems are equipped to repair and supply the whole range of Unidrive SP drives, including options to expand the functionality of the SP7412 VSD. Control Techniques design all of their variable frequency drives to be easy to install and commission, and the Unidrive SP is no different.

High Performance Motor Control

The Unidrive SP SP7412 is capable of controlling induction motors, asynchronous servo and synchronous servo motors thanks to its selection of control modes. By using the keypad, you can configure your drive to be operated in the following modes:

• Servo - Precision, dynamic control supporting a wide range of rotary and linear motors
• Closed Loop Vector - Ultimate precision control of induction motors offering full motor torque at zero speed
• RFC Mode (Rotor Flux Control) - Superior dynamic performance and stability without a feedback device
• Open Loop Vector - Good open loop motor performance with minimum configuration
• Open Loop V/F Control - A simple control algorithm that is ideal for parallel motors
• Regenerative - Active front end control mode for harmonic elimination and regeneration

Many Feedback Encoder Options

The Unidrive SP line has the hardware needed to connect to virtually any feedback encoder type, which enables the designer to select the most appropriate technology for the application.Incremental, providing a good balance of cost and performance.

• SinCos - Offers increased position resolution for precision and low speed applications
• SSI - Offers absolute position feedback
• EnDat and HIPERFACE - These encoders transfer position data using a high-speed communications network, often combined with SinCos technology

Widest Range of System Integration Features

Select the level of integrated automation/motion control, connectivity and I/O that you need by using the plug-in option modules compatible with the Unidrive SP. The SP7412 has room for three option modules, which you can select from the wide array of system integration features. AFi Systems stock a wide range of option modules that are available for immediate despatch.

• Input/Output options - Including SM-I/O 32, SM-I/O Plus, SM-I/O Lite
• PLC/Motion functionality options - Including SM-Applications Lite V2, SM-Applications Plus, SM-EZMotion, SM-Register
• Communications options - Including SM-EtherCAT, SM-LON, SM-Profibus DP, SM-Interbus, SM-DeviceNet, SM-Ethernet, SM-CANopen, SM-SERCOS, SM-CAN, SM-PROFINET
• Feedback options - Including SM-Universal Encoder PLus, SM-Encoder Plus, SM-Resolver, SM-Encoder Output Plus

Simplify Set Up with a Smartcard

Supplied with every Unidrive SP, including the 160kW SP7412 inverter, the Smartcard can be used to copy and back up parameter sets, making it easy to commission new drives. The Smartcard enables you to:

• Store parameters and programs
• Simplify drive maintenance and commissioning
• Set sequential build of machines up quickly
• Machine upgrades can be stored on a Smartcard and sent to the customer for installation

On-Board PLC

For simple drive control applications using relay logic or a micro PLC, the SP7412 drive’s inbuilt programmable controller is suitable. The on-board PLC is configured using an easy-to-use ladder logic program editor.

Back-Up Power Supplies for Continuous Operation

Ensure that your SP7412 variable frequency drive is always ready for action thanks to the back up power supplies. Start up routines are eliminated and safety back up for critical equipment is provided.

• 24VDC input for control - Allows the control circuits of {part number} Unidrive SP to remain active when the AC supply is removed. This enables Fieldbus modules, application modules and encoders to continue to operate
• 48-96VDC input for power - Allows the drives power output to control the motor, often used for emergency back-up situations such as for moving elevators to an exit during a power supply failure

AFi Systems are happy to help with all Unidrive SP SP7412 160kW inverter requests, and can ship drives and options to you quickly.

Fast Commissioning

The Unidrive SP can be set up quickly and easily thanks to the software and Smartcard. There are two types of software that can be used with the Unidrive SP - CTSoft and CTScope.

CTSoft

CTSoft is a drive configuration tool for commissioning, optimising and monitoring Control Techniques drives. With CTSoft, you can:

• Use the configuration tool to commission your drive
• Read, save and load drive configuration settings
• Manage the drives Smartcard data
• Visualise and modify the configuration with live animated diagrams

CTScope

This is a full featured software oscilloscope for viewing and analysing changing values within the drive. The time base can be set to give high speed capture for tuning or for longer term trends. The user interface is based on a traditional oscilloscope, making it familiar and friendly to all engineers across the globe.

Autotune is a feature accessible through CTSoft or the keypad to help you to get the best performance by measuring the motor and machine attributes and automatically optimising control parameters.
