SAFETY INSTRUCTIONS
ALARM –SAFETY –CAUTION
Power factor compensation capacitors.
The reactive compensation capacitors used to increase the power factor should be connected to the soft
starter input terminals and not to the output ones. These capacitors should be connected with an
additional contactor as shown in the electric connections section. The connection will be done only when
the soft starter is running and it will be disconnected during the acceleration and deceleration ramp.
Otherwise, the soft starter can be damaged.
When working in electric installations always remember to apply the 5 golden rules:
1. Visible cut of all the voltage sources.
2. Mechanic lock of every single cut elements.
3. Verify no voltage is present.
4. Earth ground and short circuit any possible voltage source.
5. Define and post sign the working area.
CAUTION
Handle the equipment with dry hands.
Otherwise, electric shock hazard existence.
Do not use cables with damaged insulation. Do not summit cables to abrasions, excessive stress,
heavy loads or pinching.
Otherwise, electric shock hazard existence.

COMMISSIONING
Before commissioning the soft starter, the user must read carefully this manual and pay particular
attention to the connection and start sections.
Verify all of the parameters and make the necessary settings before starting the equipment.
Depending on load and applications, the parameter values can be changed.
Voltage and current levels applied in terminals as external signs should be in accordance with the
manual data. Otherwise, the soft starter could be damaged.
GROUND CONNECTIONS
Electric shock prevention:
The soft starter locker chassis must be properly earth ground connected to prevent a possible electric
shock even when a leakage current flows through the locker. Disconnect all of the voltage supplies
before proceeding with maintenance operations within the soft starter or motor. Due to the existence
of capacitors in the power section, the equipment will keep dangerous voltage even when the input
voltage is disconnected. Use a cable to earth-ground it and discharge the existing voltage.
Only connect the earth grounding to the soft starter earth plate. Do not use the case or the chassis
screw for grounding.
The earth protection cable must be connected first and disconnected last.
The motor earth grounding will be connected to the soft starters’ one and not to the installations one.
The installations earth grounding will be connected to the soft starters’ one.
Equipment input cables are medium voltage cables. As shown in the figure, they are coaxial cables,
each one including earth. To carry out with a correct connection it is necessary to join every phase’s
earth and connect it to the soft starters’ earth plate.
The output cables to the motor have the same characteristics. Their earths should also be joined and
connected to the soft starters earth plate IN THE SAME TERMINAL than the input cables.

3 OV/LOAD T=5
G3.3 / Overload
curve
1 to 10
The overload curve determines the response time under overload conditions. There is a non-
linear relation between the overload parameter [G3 OV LOAD] and this parameter, in order to
set the time required for tripping on F4 OVERLOAD. If [3 OV/LOAD T =1] is selected then the
response time for an overload condition is almost immediate, but if [OV/LOAD T=10] then takes
the soft starter trips on F4 OVERLOAD after a time delay.
Setting when a fast response is needed under overload conditions, please select
[OV/LOAD T =1]. When a slow response is needed, select [OV/LOAD T =10]. For normal
operation leave this value as default [OV/LOAD T =5].
The response time for the overload protection can be calculated from the following curve:
4 OVL FAC=100%
G3.4 / Starting
Overload
Factor
100 to 500%
The parameter function is to increase the overload curve during acceleration. Recommended to
start loads with elevated torque momentum. Once the nominal rate is reached, this parameter
deactivates and the overload protection will function as it has been explained in [G3.2] and
[G3.3]. Adjust the default (100%) value for low inertia applications like pumps, fans (Torque = K
x Speed²). Mills, crushers and centrifuges (high inertia moment) will normally require a start with
low starting overload factor (150%) and increase this value until the load accelerates without
tripping on F4 OVERLOAD.

Underload current determines the current level the motor must not operate below.
Leave the adjustment to 50% of the nominal current of the motor.
Applications: This protection helps to detect mechanical problems such as broken shafts, belts,
when this occurs, the motor will run under no load conditions.
When working with pumps, this protection helps to detect no load pump operation, due to a lack
of water or pump input pipe water position.
7 UNLOAD T=OFF
G3.7 / Under

This parameter sets the maximum allowable operation time under load conditions before
tripping.
The setting depends on the application, but should be set to trip as soon as a condition occurs.
Applications: Pumps, fans.
8 SHEARPIN=OFF
G3.8 / Shearpin
current

of VS65,
OFF
The soft starter will stop immediately when the current drawn by the motor reaches this value
during normal operation. This parameter is off during acceleration or deceleration. The stop
should be done in a controlled way.
Set the current value to stop the VS65.
Application: Oversized electrical motors used for starting, but working under nominal conditions
at running, may only reach the Shearpin current because of mechanical problems locked rotors,
etc.

1 STR DELAY=0s
G4.1 / Starting
Delay
0 to 600s
Sets the time the VS65 will wait after a start command has been provided and acceleration will
start.
Adjust this value in accordance with the application.
2 PULS TORQ =50%
G4.2 / Torque
Pulse
50 to 100%
Choose the torque pulse level applied to the motor for the time specified at [G4.3].
This value’s setting must be done in conjunction with [G4.3] to initiate a first move of the motor.
3 PULS TQ T=OFF
G4.3 / Torque
Pulse Time
OFF,
0.1 to 0.9s
Sets the time for the [2 PULS TORQ] to be applied.
INIT TORQ=35%
G4.4 / Initial
Torque
30 to 99%
Establish the initial torque to be applied to the motor at the beginning of the ramp up.
When adjusting, it is recommended to begin with a low initial torque value, normally default.
Observe motor rotation immediately after start command. If the motor doesn’t spin, machine
torque requirement may be higher, and it may be necessary to increase this until the motor
starts to turn normal after a start command has been applied. If a very high current is noticed at
the very beginning of starting process, this could be due to an initial torque setting that is too
high - this must be decreased until a proper value is achieved.
Applications: For submerged pumps, generally a torque between 40% and 45% is required. For
applications such as mills or crushers, the required torque is normally between 40% and 50%.
Note: These values are typical adjustments. Each application requires individual settings to
achieve the best performance.
