• 5 start modes

• Network communication boards (accessories):

DeviceNet, Profibus-DP, Ethernet and Modbus,

RS-232 or RS-485

• Flash Memory Module (accessory)

Advantages:

• Flexible Torque control

• Overload capacity of 400% for 20 s. (2x / hour

duty cycle)

• Management of Demand restrictions by the

electric company

• Bumpless starting

• Motor protection

• Mechanical wear reduction

• Handles lower inrush current limitations of

power supply

Special Features:

• Clean Assembly with easy accessibility to all

components

• Flexible Torque Control (FTC), by employing torque

estimation using vector control principle and

measurement of input voltage, output voltage

and output current. This provides more accurate

torque set-points, compared to estimating torque

values only via current measurement.

• Active Protection offers complete motor protection

in DOL START and RUN mode. This eliminates

need for any expensive motor protection relays for

backup protection.

• Optimized heat-sink design for balanced, compact

cooling

• Power stacks are light weight, independent phase

modules for ease of handling

• Ground Fault protection is standard

• Flexible Thermal Class Curve setup & selection that eliminates

need for third party expensive protection relays

• Soft PLC function with license-free software

• Nickel plated bus bars and bus-stub connections

provide corrosion resistance and

ensure proper electrical connection

• Power connection terminals for TOP or BOTTOM

motor connection

• Operator Interface (keypad, parameter setup) is

identical to that of WEG’s low voltage starter

product line
