SINUS K INSTALLATION
INSTRUCTIONS

1. GENERAL DESCRIPTION
Inverters are electronic devices capable of driving asynchronous motors at adjustable speed.
The speed of rotation of asynchronous motors depends on the voltage frequency of the motor power supply. To
adjust the motor speed, the voltage frequency of the motor power supply must be adjusted accordingly.
Inverters are voltage generators capable of adjusting both the voltage value and the relevant frequency value at
a time.
To enhance the motor operation at any speed value, the simultaneous variation of voltage and supply frequency
must be obtained with particular criteria in order not to alter the torque characteristics of the torque produced by
the connected motor.
Inverters manufactured by ELETTRONICA SANTERNO fully meet these adjustment and control requirements and
incorporate a wide range of the latest technologies to fit any application requirement.
Available SINUS K models range from 1.3kW to 900kW.
AVAILABLE SINUS K MODELS:
NOTE
It is possible to change some technical features and to customize the inverter
enclosures shown in the picture. The proportion of one enclosure to the other is
shown as an example and is not binding.

5. STARTUP PROCEDURES
The startup procedures described below relate to commands sent via terminal board (factory setting). For the
configuration of the terminal board, see the Control Terminals section.
DANGER Before changing the equipment connections, shut off the inverter and wait at least
5 minutes to allow for the discharge of the capacitors in the DC-link.
DANGER At startup, if the connected motor rotates in the wrong direction, send a low
frequency reference and check to see if the direction of rotation is correct.
CAUTION When an alarm message is displayed, find the cause responsible for the alarm
trip before restarting the equipment.
5.1. Startup Procedure for IFD Software
1) Connection: Follow the instructions stated in the CAUTION STATEMENTS and WIRING sections.
2) Power on: Link to terminal 6 (ENABLE) is to be open when the inverter is started.
3) Parameter alteration: Use the PROG, ↓, ↑and SAVE keys to access the other parameters. See the
"Submenu Tree" in the Programming Manual.
4) Motor parameters: Access the V/f Pattern submenu and set the following: C05 (Imot) (motor rated
current); C06 (fmot1) (motor rated frequency); C07 (fomax1) (maximum output
frequency desired) and C09 (Vmot1) (motor rated voltage). Press SAVE each time a
new parameter value is set. For loads producing a quadratic pattern of the torque
with respect to rpm (turbo pumps, fans, etc..), set C11 (preboost) to 0%. Press SAVE
to store the new parameter value.
5) Overload: Set parameters C41/C43/C45 in the Limits submenu based on the max. current
desired.
6) Startup: Close terminals 6 (ENABLE) and 7 (START) and send a frequency reference: the
RUN LED and REF LED will come on and the motor will start. Make sure the motor
is rotating in the right direction. If not, operate on terminal 12 (CW/CCW) or open
terminals 6 and 7. Shut off the inverter, wait a few minutes and reverse two of the
motor phases.
7) Possible failures: If no failure occurred, go to step 8. Otherwise, check the inverter connections
paying particular attention to supply voltages, DC link and input reference. Also
check if alarm messages are displayed. In the Measure submenu, check the
reference frequency (M01), the supply voltage to the control section (M05), the DC
link voltage (M06), and the condition of terminals 6, 7, 8, 9, 10, 11, 12, and 13
(M08; a number other than 0 indicates the "activation" of the relevant terminal).
Check to see if these readings match with the measured values.
8) Additional alterations: Note that you can change Cxx parameters in the CONFIGURATION menu only
when the inverter is DISABLED or STOPPED.
You can write down any customized parameter in the table on the last pages of the
Programming Manual.
9) Reset: If an alarm trips, find the cause responsible for the alarm and reset the equipment.
Enable terminal 8 (RESET) for some time, or press the RESET key.

configuration of the terminal board, see the Control Terminals section.
1) Connection: Follow the instructions stated in the CAUTION STATEMENTS and WIRING sections.
2) Power on: Link to terminal 6 (ENABLE) is to be open when the inverter is started.
3) Parameter alteration: Use the PROG, ↓, ↑and SAVE keys to access the other parameters. See the
"Submenu Tree" in the Programming Manual.
4) Motor parameters: Access the VTC Pattern submenu and set the following: C01 (fmot) (motor rated
frequency); C02 (Speedmax) (desired maximum speed); C03 (Vmot) (motor rated
voltage); C04 (Pnom) (motor rated power); C05 (Imot) (motor rated current); and
C06 (Speednom) (motor rated speed). Also set C07 (resistance of one stator phase
for a star connection or one third of one phase resistance for a delta connection),
C08 (resistance of one rotor phase for a star connection or one third of one phase
resistance for a delta connection) and C09 (inductance of stator leakage of one
phase for star connection or one third of the leakage of one phase for a delta
connection). If values to be set in C07, C08, and C09 are not known, either use
parameter C10 to perform the parameter autotuning (see step 5) or go to step 6.
Press SAVE each time a new parameter value is set.
5) Overload: Set parameter C42 (Limits submenu) depending on the maximum torque that can
be generated.
6) Vectorial control
autotuning:
Set C10 to [YES]: close the ENABLE contact (terminal 6) and wait approx. 30 sec.
The inverter will compute the motor parameters. Open terminal 6.
7) Startup: Close terminals 6 (ENABLE) and 7 (START) and send a speed reference. The RUN
LED and REF LED will come on and the motor will start. Make sure the motor is
rotating in the right direction. If not, operate on terminal 12 (CW/CCW) or open
terminals 6 and 7. Shut off the inverter, wait a few minutes and reverse two of the
motor phases.
8) Speed regulator
adjustment:
If an overdisplacement occurs when the speed setpoint is reached or if a system
instability is detected (irregular motor operation) adjust the parameters relating to
the speed loop (“Speed loop” submenu; P100 Speed prop. Gain and P101 Speed
integr. time). Set low values for P100 and high values for P101, then increase
P100 until an overdisplacement takes place when the setpoint is reached. Decrease
P100 by approx. 30%, then decrease P101 until an acceptable setpoint response is
reached. Check that the motor runs smoothly at constant speed.
9) Possible failures: If no failure occurred, go to step 10. Otherwise, check the inverter connections
paying particular attention to supply voltages, DC link and input reference. Also
check if alarm messages are displayed. In the Measure submenu, check the speed
reference(M01), the supply voltage of the control voltage (M08), the DC link voltage
(M09), the condition of terminals 6,7,8,9,10,11,12, and 13 (M11; if a number
other than 0 appears, this indicates the “activation” of the relevant terminal).
Check to see if these readings match with the measured values.
10) Additional
alterations:
Note that you can change Cxx parameters in the CONFIGURATION menu only
when the inverter is DISABLED.
You can write down any customized parameter in the table on the last pages of the
Programming Manual.
11) Reset: If an alarm trips, find the cause responsible for the alarm and reset the equipment.

6.1. Choosing the Product
Inverters of the SINUS K series are dimensioned based on allowable current and overload.
SINUS K series is characterized by two different current values:
-Inom: continuous current that can be produced.
-Imax: max. allowable current that can be produced when the inverter is overloaded, for a time of
120sec every 20min up to S30 and for a time of 60 sec every 10min from S40 to S65.
Each inverter model may be connected to 4 different motor power sizes depending on load performance.
Typical applications have been divided into 4 overload categories to help choosing the most suitable inverter
size.
LIGHT overload up to 120%; may be connected to light loads with constant/quadratic torque
(pumps, fans, etc.);
STANDARD overload up to 140%; may be connected to standard loads with constant torque (conveyors,
mixers, extruders, etc.);
HEAVY overload up to 175%; may be connected to heavy loads with constant torque (lifts, injection
presses, mechanical presses, translation and lifting of cranes, bridge cranes, mills, etc.);
STRONG overload up to 200%; may be applied to very heavy loads with constant torque (mandrels,
axis control, etc.).
The table below indicates the overload class typically required for each application.
Dimensioning is not binding; the torque model required by the duty cycle of the connected machine should be
known.
