1. GENERAL INFORMATION

This manual contains the necessary information for the correct use of the Soft-Starter SSW-07/

SSW-08.

It was written to be used by trained or technically qualified people to operate this type of equipment.

2. ABOUT THIS MANUAL

This manual gives the necessary description for the configuration of all the functions and parameters of the Soft-Starter SSW-07/SSW-08. This manual must be used together with the SSW-07/ SSW-08 User’s Guide.

3. ABOUT THE SSW-07/SSW-08

The Soft-Starter SSW-07/ SSW-08 is a high performance product that allows start control of three phase induction motors. This way mechanic shocks in the load and current surges in the power supply can be avoided.

4. ABOUT THE SSW-07/SSW-08 PARAMETER PROGRAMMING

The basic functions of the Soft-Starter SSW-07/SSW-08 can be programmed at the front cover at the SSW-07/SSW-08 (Trimpots and DIP Switch). To program additional functions and/or visualize reading parameters, some accessories must be used, as for example: the Software SuperDrive G2, Serial Communication RS-232 or RS-485, Local or Remote Keypad. For more details see the chapter 7 of the User’s Guide and the optionals guides of SSW-07/SSW-08.

NOTE!

For communication with the SSW-07/SSW-08 use the 2nd generation programming software SuperDrive G2. The first generation software named SuperDrive is not compatible with this product.

Parameter P219, Parameterization via Keypad/ (Trimpots and DIP Switch), defines the

programming origin for the protection and acceleration/deceleration ramps. A Soft-Starter SSW-07/

SSW-08 can be programmed via Trimpots and DIP Switches or completely via parameters. See the detailed description of parameters (P219).

Parameters P220, P229, and P230 (Local/Remote Definitions) program the origin of the enable/ disable command. Factory default settings enable via digital input. To enable/disable by means of keypad or serial command the settings of P220, P229 and P230 must be changed. See the detailed description of parameters P220, P229 and P230.

The SSW-07/SSW-08 User’s Guide has a chapter dedicated to Programming Suggestions. It’s important to read this chapter before starting to program the Soft-Starter SSW-07/SSW-08.

5. KEYPAD(HMI) USE

The keypad is a simple interface that allows the operation and the programming of the Soft-Starter. It presents the following functions:

- Indication of the Soft-Starter operational status;

- Indication of the errors;

- Visualization and modification of the adjustable parameters;

- Operation of the soft-Starter ( and keys).

The keypad can be used in the following cases:

- If an keypad for commanding, programmingand/or visualizing SSW-07/SSW-08 parameters were necessary;

- For installation of the keypad at the cabinet door, commanding panel or at the SSW-07/SSW-08 front cover;

- When the copy function were necessary.

The SSW-07/SSW-08 local or remote keypad presents a 7-segment 4-digit LED display, 4 status LEDs and 8 keys. The figures below show a front view of the remote keypad and of the local keypad.

Remote Keypad Front View Local Keypad Front View

5.1. LEDs Display Functions

It shows the parameter number or its content and also fault and status messages.

5.2. Function of the “Local” and “Remote” LEDs

Soft-Starter in Local mode: Green LED on and red LED off.

Soft-Starter in Remote mode: Green LED off and red LED on.

5.3. Function of the Direction of Rotation LEDs (Clockwise and Counterclockwise)

The changing of the direction of rotation function is not available in the software version V1.3x.

5.4. Basic Functions of the Keys

- Enables the motor (start);

- Disables the motor (stop). Resets the Soft-Starter after the occurrence of errors;

- Selects (toggles) the display between the parameter number and its value (position/content);

- Increments the parameter number or the parameter value;

- Decrements the parameter number or the parameter value;

- Selects the origin of the commands between Local or Remote;

- No function in the software V1.3x;

- No function in the software V1.3x.

5.5. Signaling/Indications on the Keypad Display

Soft-Starter states:

Soft-Starter ready to enable the motor

Soft-Starter in an error condition. The error code shows up flashing. In the example we have the E03 indication (phase Loss).

Soft-Starter executing the function “Load parameters with the factory default (P204)”.

NOTES!

The display also flashes in the following situations, besides the error condition:

An attempt to change a parameter with an incorrect password (P000 – Access parameter); An attempt to change a not allowed parameter. For instance one that cannot be changed with the motor

rotating.

5.6. Parameter Viewing/Changing

All the settings of the Soft-Starter can be done through the parameters. The parameters are indicated on the display by means of the letter P followed by a number: Example (P264):

264 = number of the parameter

There is a numeric value (content of the parameter) associated to each parameter, which corresponds to the option chosen among the available ones for that parameter. The values of the parameters define the Soft-Starter programming or the value of a variable (E.g.: current, voltage). In order to carry out the soft-Starter programming one must change the content(s) of the parameter(s).

Example:

(2)

NOTES!

(1) By pressing the key after an adjustment, the last adjusted value is automatically stored in the

Soft-Starter nonvolatile memory, being kept until a new modification. (2) In order to be able to change the value of a parameter, it is necessary to set first P000 = 5. Otherwise it will

only be possible to see the parameters, but not changing them. For more details refer to the P000 description. (3) If the last value programmed in the parameter is not functionally compatible with other parameter values already programmed, an E24 –Programming Error -will be displayed. Example of programming error: Programming two digital inputs (DIx) with the same function. Refer to Table 5.1 for the list of programming errors that will generate an E24 Programming Error.

Starting with voltage ramp:

This is the most commonly used method. The Soft-Starter imposes the voltage on the motor without any kind of voltage or current feedback applied to the motor. This is applied to loads with lower initial torques or quadratic torques. This kind of control can be used as an initial working test.

Starting by current limitation:

The maximum current level is maintained during the start, being set according to the needs of the application. Applied to loads with higher initial torques or constant torques. This type of control is used to adapt the start to the capacity limits of the supply network.

heating and cooling. All calculationsare done through a complex software that estimates the motor temperature through theTrue RMS current supplied.



The actuation curves of the motor Thermal Protection are based on IEC 60947-4-2 standards.



The heating and cooling curves of the motor are based on many years of WEG motor development. They adopt the IP55 Three Phase Motor as a standardand also consider if the motor is cooling while activated or not.



The cooling time of the thermal image depends on the motor power. Inother words, for eachpower there is a different cooling time. Where there is a need to decrease this time, the P641 can be used.

The estimated value of the motor temperature is saved in



non-volatile memory every time the control card supply is removed. Therefore, after supplying the control card, the last saved value will be returned.



The thermal image can be reset, disabling and enabling the motor overload protection.

NOTE!

If there are various thermal classes it is because it is necessary to program exactly one that best adapts to its application and protects the motor inside its permitted work duty. When using a motor with a PTC thermal sensor or thermostat connected internally to the Soft-Starter, there is no need to enable the thermal classes, therefore, disable the motor overload protection. To connect a PTC thermal sensor to the Soft-Starter SSW-07/SSW-08, it is necessary to use an optional module. See the chapter Options and Accessories in the SSW-07/SSW-08 User’s Guide.

Sets the time for the auto-reset of the motor thermal image.



This function can be used in applications that need various



starts per hour or shorter time intervals between the motor start and stop.

The thermal image cooling time depends on the power of the



motor. In other words, for each power there is a different cooling time.

The thermal image canalso be reset by disablingand enabling



the motor overload protection.

7. ERRORS AND POSSIBLE CAUSES

When an error is detected, the motor is deactivated and the error is displayed. To return the Soft-Starter to normal operation after the occurrence of an error, it is necessary to reset it. This can generally be done in the following ways:

By turning off the power supply and turning it back on (Power-on reset);



Through the reset button in the front panel of the Soft-Starter SSW-07/SSW-08 (Reset button);



Automatically, through the automatic reset (auto-reset);



Via digital inputs (DIx);



By pressing the key of the keypad (manual reset);

 

 By serial communication (Serial).

Acti vation Description

- At starting: It occurs when there is no voltage in the power supply terminals (R/1L1, S/3L2 and T/5L3) or when the motor is disconnected.

- At full voltage: It trips when the current stays below the programmed value longer than the programmed time. Referring the motor nominal current. When the parameters are set with the factory default values, then this protection trips after elapsing 1 second with phase loss either at the input or the at the output (motor). It trips whe n the current c irculating through the SSW-07/SSW-08 is less than 20% of the

value adjusted at the Motor Current trimpot.

Prob ab le Ca uses

- Percentage values programmed as the maximum acceptable limit of the undercurrent (P610) is below the necessary value for the motor and the application.

- In hydraulic pump application, it may be running without load.

- Phase loss in the three-phase network.
