Features

• Motor Voltage: 2.3 kV to 6.9 kV
• Torque control - FTC - Flexible Torque Control, technology developed by WEG which uses the vector control and control of direct torque concepts, based on technologies developed for the vector frequency inverters CFW. The FTC is flexible 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 along the entire starting process
• Accessories can be easily and quickly installed by using the Plug & Play concept
• Protection degree: IP41 or NEMA 12
• Operating interface (HMI) with graphic LCD
• Real-time clock
• Medium voltage fuses
• Power and control insulated by fiber optics
• Main and Bypass Vaccum Contactors able to perform DOL start
• Flash memory module (accessory)
• SoftPLC function
• Licence-free software SuperDrive and WLP
• USB connection to PC
• Motor thermal protection - Pt-100 - 8 channels (optional accessory)
• 5 start modes
• Network communication boards (accessories):
• - DeviceNet, Profibus-DP, Ethernet and Modbus, RS232 or RS485
• Oriented Startup function presents minimum programming sequence to commence the operation
• Active Protection offers complete motor protection in DOL mode and eliminated the need of extra protection relays
• Ground Fault Protection – Standard
• Easy installation and suitable for Retrofits
• 40 years MTBF
• No need of back access

Soft-Starters are static starters that accelerate, decelerate and protect three-phase induction motors. The MV soft-starter WEG is available for power ratings from 550 kW up to 3400 kW. Voltage range: 2.3 kV - 6.9 kV.

Soft-Starters are static starters that accelerate, decelerate and protect three-phase induction motors. The control of the voltage applied to the motor by means of adjustments to the firing angle of thyristors allows the soft-starter to start and stop an electric motor smoothly.

The SSW7000 is suitable for medium voltage motors. It reduces the voltage applied to the motor at start. As a consequence, motor current and torque is reduced for a smooth start. This eliminates impacts of inrush current on the power supply and impacts of mechanical shocks on the load and the coupling. This helps in reducing maintenance of bearings, couplings, gear boxes, pulleys, belts and chains, in addition to protecting the motor.
