Soft-StarterSpecification Sheet

imagine a drive so clever it‘s simple

Soft-Starters are static starting switches, designed for the acceleration,deceleration and protection of three-phase, electric, induction motors,through the control of the voltage applied to the motor.

The ERSSW07, with DSP control (Digital Signal Processor) is designed toprovide great performance atmotor starts and stops withexcellent cost-benefitrelation. Easy to set up, itsimplifies start-up activitiesand daily operation.

The ERSSW07 is compact,contributing to optimizespace in electric panels.

The ERSSW07 alreadyincorporates all electricmotor protections.

The ERSSW07 adapts tocustomer needs through its easy-to-install optional accessories. A keypad, acommunication interface or a motor PTC input can be added to the product.

Features

• Strong reduction on mechanical stress on the coupling and transmissiondevices (gearboxes, pulleys, gears, conveyers, etc) during start up of the motor

• Increases motor and machine mechanical equipment lifetime due to theelimination of mechanical shocks

• Operates in environments up to 55°C (without current reduction for all models)• “Kick-Start” function for starting high breakaway torque loads• Avoids the “Water Hammer” in pumps• Limitation of voltage drop during start• Switched type power supply with internal EMC filter for the control electronics

(110 to 240V ac)• Soft-Starter (17 to 200 A) with built-in by-pass providing size reduction and

energy saving• Voltage monitoring of the electronics makes it possible to back-up I x t values

Applications

PLC

Network “Fieldbus”

The ERSSW07 Soft-Starters can be connected to “FieldBus”communication networks, through the Modbus RTU protocol.

Mainly designed to integrate large industrial automation plants, thequick communication networks provide advantages in supervision,monitoring and control, “online“ and complete, over the Soft-Starters, providing high performance and great operating flexibility,which characteristics that are demanded for complex and/orintegrated system applications.

For connection “FieldBus” type communication networks, theERSSW07 Soft-Starters allows the installation of plug-in type optionmodules at the front of the product. There are optional modules withModbus RTU protocol with RS232 or RS485 interface.

Programming Features

Current limitPermits to set the current limit during the start,according to the application requirements.

Voltage Kick Start

Enables an initial voltage pulse which, appliedto the motor, provides initial starting torquereinforcement. This is necessary for startinghigh breakway torque loads.

Voltage rampPermits smooth acceleration and/ordeceleration, through voltage ramps.

Built-in By-pass

Built-in by-pass minimizes power losses andheat dissipation in the thyristors, providingsize reduction and contributing to energysaving. This is available in all models.
