CHAPTER 2 - GENERAL INFORMATION
25
Programmable protections against line undervoltage and
overvoltage, and line phase imbalance;
Programmable protections against motor undercurrent and over-
current, and current imbalance between phases of the motor;
Thermal class may be programmed up to Class 45 for large motors.
The thermal memory is saved on EEPROM in case of an electronic
supply fault.
Special functions such as:
Display of the number of hours, running time, supply voltage phase,
motor current per phase, motor current in amperes, motor current
as a % of the Soft-Starter SSW-06 nominal current and the nominal
current as a % of the motor current, status of the digital inputs and
outputs;
Setting sequence after reset to factory default;
Veryexible selectionof start/stop control type,enabling the
followingselections:VoltageRamp,ConstantCurrentLimitingor

Control;
TotallyexibleTorqueControlprovidingveryhighperformance
for the most demanding applications;
Possibility of using all digital inputs, digital outputs and analog
outputsasremotePLCviaSerialandFieldbuscommunication;
Possibility of line voltage measurements monitoring by a supervi-
sory implemented through Serial or Fieldbus communication;
Monitoring and programming via software SuperDrive G2.
Indication of starting and full voltage diagnostics, and faults.
Control Hardware:
Keypad, referred to as the Human Machine Interface (HMI) with
Liquid-CrystalDisplay and easy programming.Fault conditions
can be displayed in several languages.
32Bit Microprocessor calculates the True rms voltage and current;
Measurement of the voltage and current in the three phases;
Isolated digital input for the motor PTC;
Fieldbus boards and RS-485 as options.
Power Hardware:
Compact size;
Power supply input and output connections:
Models from 10A to 820A - Input from the top and output at the
bottom of the SSW-06, with built-in By-pass contactor;
Models from 950A to 1400A - Input and output from the bottom,
without built-in By-pass contactor;
Easy assembly and maintenance;
Measurements of heatsink temperature in models 255A to 820A
through two thermostats:One thermostat to switch-on the internal
fans and the other to monitor over-heating;
Soft-Starter SSW-06 can be coupled to the motor by a standard
connection or an inside delta motor connection without requiring
optional devices.
Built-in By-pass contactor makes the Soft-Starter SSW- 06 (Mo-
dels from 10A to 820A):
More resistant to supply line oscillations after starting;
Save energy that would be dissipated through the thyristors after
the start, thus reducing the number of fans required for control
panel cooling.
