Description of symbols in the manual
It means that the following subject is very important and must be read carefully
It means that the following subject is linked to a generic danger for safety.
It means that the following subject shows the presence of a dangeruos voltage. It indicates that
high voltage may cause dangerous accidents or death.
- Before installation, connection or any operation on the inverter or on the motor, read this manual carefully, in order to
perform correct operations and to pay attention to safety rules.
Any use of the Rowan inverters and motors which may differ from what is written on this manual is strictly forbidden.
- This instruction manual is addressed to skilled personnel, who is acquainted with installation and use norms in
accordance with safety and protection standards. Both the motor and the inverter when connected may be dangerous for
things and people. The user is responsible for a correct installation, which must be in accordance with the directives in
force.
- The inverter belongs to the restricted sales distribution class in compliance with EN61800-3 standard. In a domestic
environment this product may cause radio interferences, in which case the user may be required to take adequate safety
measures.
- The inverter, the possible external filter and the motor must be earthed permanently and properly and must be protected
from the supply voltage in accordance with the directives in force.
- The max. inverter protection is obtained by B differentials, preferably 300mA-type. Internal or external anti E.M.I. filters
leakage current is <18mA; Please remind that the EN50178 directive says that, in case of leakage current >3,5mA, the
earth wire must be steady and doubled.
- When the inverter cover needs to be removed, as e.g. for DIP switches setting or for maintenance, it is compulsory to
wait for at least 5 minutes after inverter quenching for the internal capacitors to discharge. Internal components
and terminals subject to dangerous voltages (L1, L2, L3, U, V, W, F, F+, -) can be touched only in absence of power
supply and when the power supply between F+ and – terminals is <50Vdc. Please remind that most internal
components are sensitive to ESDs, so limit yourself to set DIP switches without touching any other component.
- ROWAN ELETTRONICA s.r.l. declines any responsibility for any inaccurancies contained in this manual, due to printing and/or
transcription mistakes. It reserves the right to make any variations that it considers necessary for better functioning of the product,
without prior notification.
- Regarding the data and characteristics mentioned in the manual, a max. 10% tolerance has been allowed, if not otherwise
indicated. Diagrams are mere examples and should be perfected by the customer.
- The product warranty is considered ex-works and is valid 12 months from the date of leaving ROWAN ELETTRONICA s.r.l. premises,
according to the conditions written on the specific document to be asked ROWAN Sales Department.
Compatibility of the manual with the firmware inverter version
See manual code MANU.400S.QUICKSTART.
To gather information about the active applications of your inverter, please go to Chapter 18 “DRIVERS CODING”.
Caution!
GENERAL WARNINGS BEFORE
INSTALLATION
Chapter 1
GENERAL WARNINGS BEFORE INSTALLATION
Caution!
Dangerous situations
In peculiar setup conditions of the inverter, after power losses, the motor might start automatically. The motor rotation
manual controls which can be set by the keyboard must be used with great attention, in order to prevent
mechanical damages and accidents against people. Setup errors might cause unintentional starts. At first start, in
case of faults on the inverter or of lack of power supply, it may not be possible to control the motor speed and the
direction. The rate contact can’t be held as valid for a safety stop; in some setup conditions or of inverter faults, its
disabling may not be followed by a prompt stop of the motor. Only the inverter electromechanical disconnection from the
power supply excludes any action on the motor.
The installation of the inverter in areas at risk, in presence of inflammable substances, combustible vapours and dusts
may cause fires and explosions; the inverters must be installed far from this kind of areas.
Avoid the penetration of water or any liquids into the machine in any case.
Do not perform dielectric rigidity tests on the drive parts.
Responsibility and warranty
When using the device or the internal cards take care on avoiding the generation of electrostatic
discharges (ESD) that may cause irreparable damages to some of the components.

The keyboard enables to change operation parameters (saved in eeprom) and to visualise useful data during the working
phases such as: speed reference, motor reference and frequency, motor current, line voltage and last fault occurrence.
Thanks to serial connection, the keyboard can be distanced from the panel of a control panel by a max. 25m distance.
ROWAN ELETTRONICA s.r.l. supplies on request the keyboard distancing cable.
The keyboard is made up of:
- an alphanumeric LED display, 2x16 characters, backlit
- four mechanical keys that give the feel of the key that has been pressed
- two signalling LEDs, one for run (RUN) and one block for fault (FAULT)
ESCAPE key enables to return to the menu or to the higher level
PROGRAM key enables to enter the submenus, to modify parameters and to save
UP key enables to scroll the displayed variables ONWARDS and to set the numerical variables in the parameters
modification towards positive values
DOWN key enables to scroll the displayed variables BACKWARDS and to set the numerical variables in the
parameters modification backwards to negative values
To speed up the setup of parameters with high values, follow the instructions below:
When you are increasing a value (meant without comma) by pressing UP key, if after 4/5 sec. you press DOWN key once,
hundreds and successively thousands will be modified and so on.
To go back to normal speed with units and tens frequency, press UP key again.
In the same way, if you are decreasing the value by DOWN key, UP key will speed up setup.
- Press the P key, so par. 1.1.1 LINE VOLTAGE will be displayed.
- Press UP key to selec par.1.1.2 MOTOR NOM CURRENT.
- Press P key; the display area for the numerical value to be set will start flashing to signal that it is now possible to
modify its value by UP and DOWN keys.
- Press UP key to increase the value and DOWN key to decrease it.
To confirm the value setup, press P key; to exit without any modifications press ESCAPE key; in both cases the number
will stop flashing.
ESCAPE key always enables to exit from the programming and to return to higher menus to DISPLAY STATUS. The
parameters modifying procedure by string selection is alike and in that case UP and DOWN keys will select the available
strings in the menu instead of numerical values.
The machine starts in DISPLAY MENU and shows one among the 10 default variables from the 2.1 DISPLAY VARIABLE
menu. Use UP and DOWN keys to scroll variables. The last variable selected is displayed when starting. See Chapter
10: PARAMETERS AND VISUALISATIONS, on paragraph “DISPLAY STATUS description” to change the default variables
displayed.

LINE VOLTAGE
1.1.1 400.V Set the inverter supply voltage to the L1, L2, L3 terminals.
Choose the voltage which is the closest to the supply voltage true value. Setup range from
150.V to 600.V
Start programming by RATE contact off. The rate contact cannot be held as valid in case of safety stop, since in case of
particular programming conditions or of inverter fault, its disconnection might not determine the sudden motor stop.
For safery reasons, it is better to be close to the emergency button to block supply to the TG contactor coil supplying the
inverter.
The storage of the inverter for longer than 2 years could damage the DC link capacitors, which shoud be restored: in
order to do that, it is suggested to supply power to the inverter in OFF rate for at least 2 hours.

Installation in vectorial mode
Connect the inverter with ref. to the Vectorial connection diagrams on the previous page.
Before installation, check the torque characteristics table regarding the possible match between G-Series Rowan
motor and the inverter in hand. In order to do so, it is important to have a look at par. Guide to “Motor/Inverter pairing
off” tables in Chapter 19: G-SERIES ROWAN MOTORS.
The tables sum up parameters setups to perform to operate the machine
- Disable the rate (RUN light off)
- Press ESCAPE key until 100.1 MOT CONTROL TYPE parameter is displayed.
-Press PROGRAMkey andset VECT_ENC fuctionin par.100.1 MOT CONTROL TYPE.
- Press ECSAPE key to return to DISPLAY STATUS.
- Press PROGRAM key to modify the following parameters from BASIC DATA menu:
- Set the encoder pulse nr per rotation in par.1.6.1 E1 ENCODER LINES. See the values on the plate of the motor encoder.
The following parameters can be got out of Chapter 19: G-SERIES ROWAN MOTORS- “Motor/Inverter pairing off” table.
As for motors which haven’t been manufactured by Rowan, see Chapter 16, par. “STANDARD ASYNCHRONOUS
MOTORSINVECTORIALMODE”.
- In par. 1.6.2 KG GAIN, set the speed regulator proportional gain.
- In par. 1.6.3 KI GAIN, set the speed regulator integral gain.
- In par. 1.6.4 VECT MAGNET CURR, set the motor magnetizing current in % ratio to nominal current.
- In par. 1.6.5 ROToR CONSTANT, set the motor rotor constant in Hz.
- In par. 1.10.1 MAX TORQUE, set the max. torque value in % ratio to nominal torque.
- In par. 1.10.15 ADAPT PERC TORQ, set the torque displays/setups adaptation value in %.
- In par. 1.10.16 ADAPT TORQ (Nm), set the torque displays/setups adaptation value in nr.
- In the end in par. 1.12.1 PWM FREQUENCY, set the value 5.00Hz, optimum PWM frequency for vectorial control.
For high power motors, in case of no particular needs for uniformity in rotation, a 3KHz- PWM frequency enables a lower
heating up of the power modules and a better exploitation of the inverter.
For PWM frequencies higher than 5KHz, for noise reasons, keep in mind that you need to derate the inverter following the
rule in Chapter 5: TECHNICAL FEATURES.
- Press ESCAPE key more than once to return to DISPLAY STATUS.
- Start with the potentiometer set so that the speed in SPEED REFERENCE is 0 rpm.
- Enable the rate (RUN light on) and check the correct sped adjustment on the potentiometer, by verifying the display of
thefollowingvariables: SPEED REFERENCE,MOTOR SPEED andENCODER SPEED. All variablesmustdisplay the same
speed rate and the same sign.
- Select MOTOR CURRENT variable and check the motor absorbption is correct if considered the present load conditions.
SPEED REFERENCE
0.rpm ENCODER SPEED
0.rpm
Check the display in ENCODER SPEED variable; on this variable a different speed from that displayed in SPEED
REFERENCE may be visualized, but this must be of the same sign:
- if the speed sign in ENCODER SPEED is opposite to that in SPEED REFERENCE, invert the A and A- encoder channels
connected to 34-35 terminals.
QUICK INSTALLATION IN
VECTORIAL MODE
Chapter 4
While performing the final rotation test to verify the speed setup
by the potentiometer, check the following variables as well, by
selecting them by UP and DOWN keys.
Caution!
FollowChapter 3: QUICK INSTALLATION IN SCALAR MODE, bygetting outof the“Motor/Inverter pairing off” tableson
Chapter 19 the common setup of the following parameters: 1.1.2 MOTOR NOM CURREN, 1.1.3 MOTOR NOM FREQUE,
1.1.4 MOTOR NOM VOLTAGE, 1.1.5 MOTOR POLES. As for motors which haven’t been manufactured by Rowan, get the
information from the motor plate.
Adjust the potentiometer, so that SPEED REFERENCE displays the max. speed.
Default speed adjustment through AI1 analog input is monodirectional; if you need it to be bidirectional, set par. 4.3.1.3
TYPE INPUT = -10V/+10V
Caution!
End of quick installation.
