GENERAL RECOMMENDATIONS
BEFORE INSTALLATION
Three-phase 470 series drive have been created with 4 programmable features (see Chapt. 2 DRIVE FUNCTION
SELECTION):
- SOFT-STARTER: to start/slow down three-hase asynchronous motors.
- STATIC SWITCH: to statically command three-phase loads in alternative to electro-mechanical contactors, by ZERO
CROSSING antijamming managing.
- POWER/ENERGY REGULATOR: to control the temperature in ovens with electric resistances by wave- train regulation
in ZERO CROSSING.
- VOLTAGE REGULATOR to control voltage/current on Rowan High slip motors and in general on feeders voltage/current
adjustable; the voltage is adjusted by the PHASE PARTIALIZATION technique.
For this reason, this manual is divided into the following parts:
- Chapt. 1-2-3-4 gives instructions common to all functions.
-Chapt. 5-6-7-8-9 describe SOFT-STARTER function (see Chapt. 1 and 5 for a quick start-up of the function).
- Chapt. 10 describes technical characteristics common to the following functions:
STATIC SWITCH, POWER/ENERGY REGULATOR, VOLTAGE REGULATOR.
Chapt. 11 describes the STATIC SWITCH function.
Chapt. 12 describes the POWER/ENERGY REGULATOR.
Chapt. 13 describes the VOLTAGE REGULATOR.
ATTENTION! Before starting, select the function needed by reading chapt. 2 -
"DRIVE FUNCTION SELECTION"
ROWANELETTRONICA s.r.l. declines allresponsibilityforany imprecisions inthismanualdue toprintingand/orcopy errors.
Moreover it can make changes any variations it may deem necessary to improve the products under its sole discretion and
without notice.
The data and characteristics provided in this manual have a maximum tolerance of ±10%, unless otherwise indicated. The
diagrams are mere guidelines and should be adapted to the specific needs of the user.
Before installing , wiring or any other operation on the actuator, carefully read this manual to ensure that the correct
operations are made and all related safety measures are taken.
It is strictly forbidden to use the 470 actuators in any way other than for the operations indicated in this manual.
This instruction manual addresses qualified technicians who know the standards to respect in the installation and
operation of the actuator, in compliance with safety regulations and the protection of this type of equipment.
The actuator and its load can create hazardous situations for the safety of objects and individuals, the user and installer
must comply with statutory regulations.
This actuar presents a a current lekeage to ground (<1mA), so DO NOT supply it without connecting the PE terminal to
ground first.
The drive doesn't have any SIL ability (Safety Integrity Level) as per standard IEC/EN61508, so drive contacts cannot be
considered a valid method for a safety stop; in certain programming or actuator fault conditions, its shut down may not
mean that the motor will stop immediately. Only an electromechanical cut-off of the actuator from the power supply,
made by following IEC/EN61508 standards, will safely cut-off any motor command.
In the same way, in case of SOFT-STARTER function,the shaft stopped detector cannot be considered valid to carry out
operations in total safety (SIL ability).
Installation of the actuator in risky zones, containing flammable substances or combustible vapour or dust, can cause fire
or explosion. The 470 actuators must be installed away from such zones.
In all events prevent water or other fluids from penetrating the interior of the appliance.
Do not carry out dielectric rigidity tests on parts of the drive.
The product warranty is provided ex works Rowan E.; Terms and conditions are specified on the Sales Conditions that can
be requested to the Commercial Dept. or downloaded from our web site: www.rowan.it

36030 - CALDOGNO - VICENZA - ITALY THE KEYPAD
Chapt.1
The keypad is used to modify the operating parameters (stored on an eeprom) and view parameters and measurements
during processing. The serial connection allows the keypad can be remote connected to the panel of a control switchbox, at a
maximum distance of 25 meters.
On request, Rowan Elettronica can supply the keypad remote connection lead.
General overview of the keypad
Button descriptions
The keypad comprises:
-A backlit alphanumerical display with 2x16 characters .
-Four pushbuttons with pressed feeling.
-Two LED's signalling drive (RUN) and fault block (FAULT).
ESCAPE returns to the start menu or a higher level and saves the settings.
PROGRAM, enters the submenus and the parameter change mode with sequential digit selection for number
settings.
UP, scrolls the variables FORWARD and increases the number setting selected by PROGRAM button.
DOWN, scrolls the variables BACKWARD and reduces the number setting selected by PROGRAM.
For example, SOFTSTART function, to modify the parameter 1.2 MOTOR In under the 1. BASIC DATA menu :
> Press P to view the 1. BASIC DATA menu
> Press P to view the first parameter in the 1.BASIC DATA menu, the 1.1 LINE FREQ parameter.
> Press UP to select par.1.2 MOTOR In.
> Press P to enter the modify parameter mode:
the display box with the rightmost digit of the setting will start blinking to indicate that it is now possible to modify it by the
UP and DOWN buttons.
> Press UP to increase and DOWN to decrease the setting.
> To modify the other digits just press P briefly, every time it is pressed the next digit to the left is selected, until it reaches
the leftmost and then returns to the rightmost and so forth.
> If the parameter can be both positive or negative, the sign is shown after the leftmost digit; to change it press P until it is
selected and then use UP to set + and DOWN to set -
> To memorise the new setting press ESCAPE (the selection will stop blinking).
> To return to the initial menu (DISPLAY STATUS) press ESCAPE again. To modify parameters with string selections use
exactly the same procedure, in this case UP and DOWN will select the strings available instead of numbers.

With par. 3.1 ENABLE CLASS 10 to YES you will enable the motor protection as specified by regulations for Class 10. Class 10 provides
times and overloads for cold and warm motor, above which Fault 1 steps in .
The curves with the times / overloads are below:
FAULT1 "MOTOR OVERLOAD" description (on SOFT-STARTER function only)
Is is the starting current, In is the rated motor current set in par. 1.2 or in par. 5.1 (if you selected the second speed).
Is / In = ratio between starting current and rated motor current.
The softstarter internally simulate the motor winding heating basing on the absorbed current during a certain time (i2t motor). If beside IxI
MOTOR you read "Cold", the motor is cold and when starting (or with overloadings) consider the "cold" times of the curve. If beside IxI
MOTOR you read "Warm", the motor is considered hot and when starting (or with overloadings) consider the "warm" times of the curve.
At starting, to obtain the times shown by the curves it is necessary that IxI MOTOR is 0%, otherwise times will be lower.
To bring the variable IxI MOTOR from 100% to 0%, you need 15 minutes; this is the maximum time to be wait after the starting in order
to obtain the maximum times allowed by the Class 10 curves.
Fault 10 protects the drive against overloading, the maximum rated current (Imax) in continuous service corresponds to the maximum
setting limit of the parameters par. 1.2 or 5.1.
The soft starters are designed to withstand cold start with inrush currents (Is) corresponding to 4 times the current maximum permissible
continuous service for 20s.
Consequently, the response times of FAULT10 are shown in the chart below:
However, if IxI DRIVE exceeds 0% and starts to increase, we enter the area of intervention FAULT10.
If, after an overload , the current decreases under the threshold value, the variable starts to decrease and from 100% to 0% it takes
about 5min and 30s. After a starting, if scr are still hot, next startings will have shorter admitted times depending on the IxI DRIVE
residual content and on the thermic simulation by scr junction.

SERIAL
COMMUNICATION
Chapt.4
The MODBUS RTU protocol establishes asynchronous communication between a MASTER device (e.g. plc, pc, etc.) and
several SLAVE devices (in this case the 470 series actuators) connected by an RS485 interface
HALF-DUPLEX (i.e. simultaneous transmission and reception is not possible) with a 2-wire connection.
Only the master can query the slaves that can only respond; each character of the message is composed as follows:
1 start bit , 8 bits for the data, 1 bit for the parity, 1 or 2 stop bits
In 470 series actuators the type of parity and number of stop bits can be programmed together with the transmission speed at
the following baudrates: 9600, 19200, 38400, 57600, 76800, 115200.
For every correct write or read message del master , a slave response messagge is provided.
The integrity of data exchanged between master and slave is verified by the CRC16 algorhythm.
If the slave verifies an incorrect CRC and cancels the response messagge to the master.
The master/slave message contains the univocal address of the slave being queried, from 1to 100
The master/slave message contains the FUNCTION CODE required of the slave .
The modbus protocol offers several functions but in the 470 series only the following are available:
- READ 1 OR MORE WORDS (maximum 20) (FUNCTION CODE=03H)
- WRITE 1 OR MORE WORDS (maximum 20) (FUNCTION CODE=10H)
If the master sends the slave a message with incorrect instructions , the protocol provides a slave response containing an
error code(MODBUS EXCEPTION CODE).
The 470 series actuators are programmed to communicate to the master the following error codes:
- ILLEGAL FUNCTION (Modbus exception code=01H)
- ILLEGAL DATA ADDRESS (Modbus exception code=02H)
- ILLEGAL DATA VALUE (Modbus exception code=03H)
More detailed information on the modbus standard can be obtained from http://www.modbus.org
Description of modbus RTU serial transmission
All parameters of this setting are on the SERIAL COMUNICAT menu.
All functions have the same menu but with a different numerical order:
- SOFT-STARTER function > menu 10.
- STATIC SWITCH and POWER/ENERGY REGULATOR functions > menu 2.
- VOLTAGE REGULATOR function> menu 6.
For example, on SOFTSTARTER function, the menu will be as follows:
Serial Communication Parameter Description
The modbus address (ID MODBUS) specified in the tables with the full parameter list into the descriptions of functions ;
the parameters values with this address are written in the RAM memory and are not saved when the actuator is shut off.
To make the actuator save the setting permanently in the internal EEPROM just add 10000 to the addess in the tables.

Typical serial wiring diagram for 3x 470 series of plc commanded actuators:
In the above wiring example there will thus be the Plc (first in the line) and the 470S address 3 (last in line), both ending with
the characteristic resistive network. The default settings of SW2 micro-switches 1,2,3 are closed and IF 3 actuators are
required on the same serial bus, SW2 micro-switches 1,2,3 can be left closed.
Wherever possible, the common 0V connection between master and slaves avoids hazardous voltage differences
between the serial bus components and generally improves EMI immunity (terminal 36, 0V)
Recommendations for the wiring connections :
Maximum connection distance 1200m.
Use screened cable with 2 twisted wires having a 120ohm characteristic impedence.
Connect the cable screen to every node nodo on an ample earthing system.
Wherever possible use screened cables for the motor connections, at least apply ferrite rings .
Avoidpassingthe motoror braking resistancecables inparallelwith the serial connection cable, and ifthis is notpossible, leave
a space of at least 200mm.
If the serial cable has to pass over the motor or braking resistance or any other power cable that may generate interference,
attempt to make sure a 90° intersect angle is kept.
In particularly disturbed environments , the installation of a ferrite ring in the ingoing and outgoing connecting
cables of the AB serial connection improves EMI immunity.
The serial transmission status can be verified by the LED's next to the serail connection terminal block of the actuator:
The components of the serial bus must be connected in daisy-chain as shown in the example.
The first and last component of the bus must end the seriale line with the resistive network illustrated below, which are built
into the 470 actuator and setting to ON SW2 micro-switches1,2,3 (the micro4 setting is irrelevant ) that are accessible on the
outside next to the bus signal terminal block.

The soft-start should be connected as shown in the wiring diagram below (example of a 3-wire connection) with the
following recommendations:
- To mount the soft-start inside a switchbox consult chapt.7
- Use GL type fuses, for their size consult the tables in chapt.6 according to the actuator code.
- If only one direction of rotation is required just connect only one relay switch (unless the braking is used as described in
chapt.9 ); the pc board commands the external relay switches with max 5A/250VAC contacts, for greater loads an external
power relay is necessary.

Chapt.5
PARAMETERSETTINGS
- Before setting any parameters, read chapt.1 with the keypad instructions.
When the power supply is connected the keypad display will always go in "DISPLAY" mode and give the last monitor variable
selected before being shut off .
To make the rapid installation easier, the basic parameters required to start the motor are accessible in the first menu level,
proceed as follows:
- Press P to select the 1. BASIC DATA menu.
- Press P to enter 1.BASIC DATA and program the following parameters, selecting them with UP :
- par. 1.1 LINE FREQUENCY > enter the supply line frequency.
- par. 1.2 MOTOR In > enter the rated current of the motor to start.
- par. 1.3 ACC RAMP > enter the time in seconds of the voltage acceleration ramp that has to be applied to the motor so
astoobtainthesoftstarting.Attention: this parameter setting does not corresponds to the real motor acceleration ramp,
this is a voltage ramp to be set to the minimum necessary value, to avoid mechanical shock or pipe hammering on
pumps. We suggest not to get over 5 secs.
- par. 1.4 ACC/DEC Imax > enter the maximum start current as a % of the rated current at par. 1.2 MOTOR In ;
begin with the default setting (400%) and then modify it according to the real limitation requirements. In all cases
the maximum current must allow the motor start-up in greatest load conditions, leaving a margin to avoid stalling.
-par.1.5STARTINGVmax> enterthestartplatformvoltageasa%ofthesupplylinevoltage;beginwiththedefaultsetting(60%)
and then modify it to obtain a prompt start, but without jerking the mechanics (the higher the platform voltage, the earlier the start ).
- The basic parameter settings for the rapid installation are complete.
START-UP
- To begin the start-up, press briefly FORWARD or REVERSE and to stop press STOP.
- To avoid the FORWARD/REVERSE commands being self-primed do not connect the STOP command.

1) The power that can be applied to the soft-starter, provided in the tables, refers to the rated power of the asynchronous motor
as provided on its ID plate.
2)Allsoft-starters(C470S/6andC470S/9excluded)cansupport4timesthestart-upoftheratedcurrentofthefieldofcalibration
(IMAX,see tables) for maximum 20 seconds every 5 minutes (300sec.); To the maximum setting limit of the starting current
(400%),a start of 4,6 times the rated current is allowed for 16 seconds (see description on parameters 1.4 and 5.3). Over
this current the soft-start is blocked by fault10.
If longer or repeated starts are required in a period of 5 minutes (300 seconds), the soft-start size has to be determined by
recalculating the IMAX by the following equation:
Dimensions
Notes on the choice of soft-starter
In this example a soft-start with IMAX just over 312A and a maximum starting current at 840A will be selected; so with a 400Vac
the supply line and 3-wire connection, the soft-start to use is 470S/8 (IMAX=400A and Isurge=1600A)
Note: The soft-starter power must never be less that the rated power of the motor
After this calculation, you also need to verify that the Isurge is lower than the MAXIMUM STARTING and DECELERATION
CURRENT allowed by the soft-starter (see tables CURRENTS and POWERS at 3 AND 6 WIRE CONNECTION). If this value
is not lower, you shall choose the bigger size allowing the requested surge.
E.G.: Tavv = 60sec , Isurge = 840A, One starting every 4 minutes -> Navv=5min/4min= 1,25
Tavv = start time at Isurge (sec)
Tavv x Navv
IMAX (A) = 300
Isurge Isurge = maximum start/deceleration current (A)
Navv = number of starts every 5 minutes (300sec.)

For a correct cooling, install the actuator as above, accounting for the following recommendations:
-Make sure that the installation environment is within the ambient conditions provided in chapt.6
(temperature - humidity - protection rating).
-Install it in the area of the switchbox designated for the power components avoiding proximity to low voltage analog and
digital circuit boards (e.g. opposite side of sheet metal).
-Favour maximum cooling airflow, avoiding to stack actuators and leaving at least 100mm space over and under each
actuator and at least 50mm each side.
-Avoid excess vibration and knocks.
The actuators in the 470S series operate correctly with temperatures on their housing and inside the switchbox between -
5°C and +40°C; higher or lower temperatures can give rise to malfunctions; it is best to position the circuit boards away
from head sources and ventilate the switchbox in high ambient temperatures; if the environment is saturated with corrosive
gas (e.g. tanneries/dye shops) the cooling air must be supplied from outside or a BYPASS made or fit the switchbox with
airconditioning.
This actuator presents a a current leakage to ground (<1mA), so DO NOT supply it without connecting the PE terminal to
ground first.
To best things to do to limit disturbances induced by the connecting cables:
-Avoid passing connection cables of the command terminal block in the same conduit as the power cables.
-Connect potentiometers, DC signals with screened cable and connect the end of each screen independently to the
common earthing point of the switchbox.
-Avoid earth rings.
470S series actuators, used as soft-starters, are temporary regulation devices designed for an industrial environment as per CEI
EN60947-4-2 standard that, after the start-up of the motor, return to the emission limits conducted on the supply line without the
additionoffilteringelements.If itisnecessarytorespect the limitsforadomesticenvironment contacttheRowanE.TechnicalDept.
