SP1201 Control Techniques Unidrive SP Panel-Mount Universal Variable Speed AC Drive

The Nidec / Control Techniques Unidrive SP Series Universal Variable Speed AC Drives are a complete drive automation range that covers the power spectrum from 0.37kW to 1.9MW. All drives share the same flexible control interface regardless of the power rating. Drives are packaged in three formats: Panel Mount, Free Standing and Modular.

The Nidec / Control Techniques Unidrive SP Series panel mount drives are standard AC input, AC output modules for installation within a control panel. The modules are easy to install and can be applied in a wide range of applications.

The Nidec / Control Techniques Unidrive SP Series Free Standing drives offer fully engineered drives that are manufactured within a standard sized cabinet. Free Standing can be ordered with input power equipment to facilitate immediate connection to the power supply and motor.

The Nidec / Control Techniques Unidrive SP Series Modular drives offer maximum power system design flexibility. Drive modules can be connected together in a variety of ways to create common DC bus systems, active input systems for returning excess energy to the power supply and parallel drives for high power motors. All drive modules are compact for easy handling.

The Nidec / Control Techniques Unidrive SP Series provides high-performance motor control for induction motors, asynchronous servo and synchronous servo motors. The control mode is simply selected using the drive keypad. 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.

The Nidec / Control Techniques Unidrive SP Series includes the hardware required to connect to virtually any feedback encoder type, allowing the designer to select the most appropriate technology for the application. Incremental - Offers a good balance of cost and performance. SinCos - Provides increased position resolution for precision and low speed applications. SSI - Provides absolute position feedback. EnDat & HIPERFACE - These encoders transfer position data using a high speed communications network, often combined with SinCos technology.

Click-in option modules allow you to customize the drive to suit your needs. Over 25 different options are available including Fieldbus, Ethernet, I/O, extra feedback devices and automation controllers.

The Nidec / Control Techniques Unidrive SP Series allows the drive system designer to embed automation and motion control within the drive. This eliminates communication delays that reduce performance while CTNet, a high performance drive-todrive network, links the different parts of the system.

The Nidec / Control Techniques Unidrive SP Series is designed using a well proven development process that prioritizes innovation and reliability. This process has resulted in Control Techniques having a market leading reputation for both product performance and quality.

The Nidec / Control Techniques drive based safety features provide an intelligent, programmable approach to meet modern functional safety standards. Machines can intelligently interact with people, increasing human protection and safety while enhancing the machine productivity.

The Nidec / Control Techniques Unidrive SP Series enables system designers to reduce costs. Standard features such as integrated EMC filters, through panel mounting and backup power supply inputs reduce cabinet size and eliminate external components.

In most applications variable speed drives reduce energy consumption by matching the motor speed to the required load.

In applications where there is a significant amount of stored mechanical energy, the drive must be able to dissipate the energy to control the motor speed. This presents a further opportunity to reduce energy consumption by returning the excess energy to a shared DC bus or to the AC supply.

DC bus and active input systems can be configured using either Unidrive SP Modular or panel mount drives. DC bus systems reduce running costs by circulating energy between braking and motoring drives. Active input systems return excess braking energy to the mains supply. Benefits include: Energy saving, Sinusoidal input current (low harmonic content), Unity or controllable input power factor.

The Nidec / Control Techniques Unidrive SP Series is quick and easy to set-up. The drives may be configured using a removable keypad, Smartcard, or the supplied commissioning software that guides the user through the configuration process.
