soft starters
WEG Soft-Starters are micro processed, fully digital, state-of-the-art products designed to ensure the best starting and stopping performance of induction motors. The human-machine interface (HMI) allows easy adjustment of the parameters which helps in set up and operation. The WEG soft starter line is class leading with features that allow the starting, stopping and protection of electric motors in an easy and efficient manner.
Low Voltage Soft Starters
SSW 05 Plus
The SSW-05 Plus Micro Soft-Starters, with DSP control (Digital Signal Processor) have been designed to supply excellent performance during starting and stopping of electric motors with an excellent cost/benefit ratio. The Operator Interface allows easy parameter setting, simplifying the start-up and operation activities. The SSW-05 Plus Micro Soft-Starters are compact, optimizing the space in electrical panels. The SSW-05 Plus already incorporates protection for the driven motor.
WEG Superdrive Software for SSW-05 Plus
The Windows-based Superdrive software can be used for setting parameters, control and monitoring SSW-05 Soft-Starters. It allows setting parameters on-line directly to the Soft-Starters and/or setting of parameters off-line into a file. With this software package users are able to store user parameters from existing SSW-05 Soft-Starters. The communication between the Soft-Starter and the computer is provided through RS-232 serial interface.
SSW 06
WEG SSW-06 series soft-starters are micro-processor controlled, fully digital and designed with state-of-the-art technology. Excellent acceleration and deceleration control is achieved with an optimized cost to benefit ratio.
The HMI allows easy programming during commissioning and operation. The built-in “Pump Control” function gives optimized pre-set pump application parameters, avoiding “Water Hammer”.
Built-in by-pass reduces power and heating losses in the thyristors, providing size reduction and energy saving. It is available in the models from 10A up to 820A.
SSW-06 soft starters have a programming option specially developed to simplify the start-up, by an oriented and automatic sequence that guides the user to the sequential programming of the minimum characteristics required for adaptation of the soft-starter to the driven motor and load.
The SSW-06 soft-starters can be communicated to fieldbus communication network through the most common standard protocols in the world including Modbus RTU, Profibus DP / DP-V1, DeviceNet, DeviceNet Acyclic, Ethernet / IP and Ethernet / Modbus / TCP.
Mainly intended to integrate large automation plants, communication networks offer many advantages in the supervision, monitoring and on-line control of the soft-starters, providing high performance and great operational flexibility.
To be connected to communication protocols, as Profibus, DeviceNet and EtherNet, optional modules need to be fitted in the Soft Starter. For connecting the SSW-06 to Modbus RTU network the RS-232 or RS-485 adapter can be used.
Besides providing protection, monitoring and motor control, it is allowable the use of digital and analog I/Os of the SSW-06 as a remote unit in a Profibus DP network.
SSW-06 Soft Starters have a SoftPLC resource that provides PLC functions in the SSW-06 giving flexibility to the user and allowing development of customized user application programs.
WEG’s Windows-based Superdrive software package for the SWW-06 Soft Starter provides easy programming, control and monitoring of the soft starter. Features of the software include automatic SSW-06 identification, Read/Write parameters, Online/Offline parameter settings for user application settings, application documentation creation. The Trace Function of the software can provide the user with the soft starter’s status through waveforms and can help with troubleshooting problems.
SSW 07 and SSW 08
The SSW-07 and SSW-08, with DSP (Digital Signal Processor) control were designed for high performance on motor starts and stops with an excellent cost-benefit ratio. Easy to set up, it simplifies start-up activities and daily operation.
The SSW-07 and SSW-08 are compact optimizing space in electric panels. It already incorporates electric motor protection. It adapts to customer needs through its easy-to-install optional accessories. Thus, a keypad and a communication interface or a motor PTC input can be added to the product.
The SSW-07 and SSW-08 series soft starters have been developed to achieve the best cost benefit ratio. The by-pass built-in allows energy saving as well as increased Soft Starter lifetime.
The SSW-07 and SSW-08 are equipped with the same functionalities, being the SSW07 applied for heavy load starts and the SSW-08 for light and moderate load starts. The SSW-07 and SSW-08 soft-starters can communicate with fieldbus communication network through some of the most common standard protocols in the world including Profibus DP (with MFW01), DeviceNet (option), Modbus RTU RS-232 (option) and Modbus RTU RS-485 (option).
Mainly intended to integrate large automation plants, communication networks offer many advantages in the supervision, monitoring and on-line control of the soft-starters, providing high performance and great operational flexibility.
To be connected to communication protocols, as Profibus DP and DeviceNet, the SSW-07 and SSW-08 Series offer plug-in accessories to install according to the desired protocol. For the Modbus RTU protocol, the connection can be done via RS-232 or RS-485 (optional) interface.
Both SSW-07 and SSW-08 Series have built-in bypass to minimizes power losses and heat dissipation in the thyristors, providing size reduction and contributing to energy saving. This is available in all models.
Medium Voltage Soft Starters
The SSW7000 uses state-of-the-art technology to provide smooth start / stop control and overload protection for three-phase medium voltage induction motors. Developed to ensure excellent performance, the SSW7000 reduces mechanical shocks from impacting the driven machinery as well as limiting the inrush current demand on your power system. The SSW7000 offers a complete solution for all your applications.
The SSW7000 features FTC®, Flexible Torque Control. This unique WEG technology uses vector and direct torque control concepts, based on VFD technologies developed by WEG. FTC is used to select the desired torque control according to the type of load applied to the motor (constant loads, quadratic loads, or loads with lower or higher starting torque), providing a smooth start with a linear speed ramp during the entire starting process.
