WORKING PRINCIPLE
The 380S drive was designed to control the speed of Rowan high slip (S series) motors, which are equipped with a
tachometricaldynamo;itisathreephasevoltageregulatorwithtachometricalfeedback,whichusescontrolleddiodes(SCR)
piloted by a phase chocking system. The voltage that pilots the motor is the result of an analogic process, that maintains
constant revolutionsbymeansof differentialcontroloftheactualmotorspeed,obtainedfrom thetachometricalgenerator,
andthatset byapotentiometer orbyan external analogicsignal.
Combined with a Rowan high slip three phase motor it creates a extremely quiet and uniform system with
constant speed and coupling , from zero until maximum motor revolutions. The choice of controlled diodes
for the power section (moreover already over dimensioned) guarantees reliability in case of extra voltage or
extra current. The 380S driver is bidirectional, the motor speed and sense of rotation are set respectively
to the value and the polarity of the reference signal with a maximum range of ±10VDC.
Theoperationisextendedtoallofthe4quadrants;thecombinedmotor isabletogenerateamotioncouple andbrakingcouple
in both senses of rotation with a peak capacity of up to 3 times the nominal couple . The ROWAN 380S+ high speed motor
system isparticularlyindicatedthereforeforfastmovements(e.g.:axlecontrol)alsowithlarge inertialloads,notneedingany
externaldevice suchas thebrakingresistanceusedfor frequencycontrol of normalasynchronous motors orforDCmotor

Themaximum speedisset bythe revolution regulation potentiometer, andthe maximumpull bythe couple regulation
potentiometer, which limits the controlled motor current using a closed loop with an amperometric transformer (TA); the
maximum couple regulation potentiometer field may be set by trimmer P8 MAXIMUM COUPLE and by the use of the TA
(current plug connected and a number of wire passes) which must be connected to connectors TA-0V.
Theboardisdesignedtooperatewithanamperometricaltransformertype151/110witharangeof4VAC.2AsuppliedbyRowan

Plug 1 - 2 = maximum output 25A
Plug 1 - 3 = maximum output 50A
