STANDARD CONFORMITY

Drive Code 119/92 is in conformity with the general IEC EN 60204-1 standard corresponding to the
essential safety requirement of the "Machinery Directive 89/392/CEE", modified by the CEE
Directive 91/368 - 93/44 - 93/68. In particular, regarding the Electro-magnetic Compatibility (EMC)
in industrial environment, drive Code 119/92 is in conformity to the product CEI EN 61800-3
standard, for "VARIABLE SPEED ELECTRICAL DRIVES" if connected to the network through a
filtering device as indicated by diagrams on page 9 and installed as written on page 8.
Ask Rowan El. for choosing the correct anti E.M.I. Filter (ELECTROMAGNETIC INTERFERENCE).

WORKING PRINCIPLES

Drive code119/92 is a single-phase voltage regulator with tachometer feedback using controlled
diodes (SCR) driven by a system at phase partialization.
The voltage supplying the motor results from an analog process mantaining constant rotations by
means of the differential control between the real speed reference taken from the tachymeter generator
and the one set by the potentiometer or external analog voltage. The coupling with the asynchronous
single-phase high slip Rowan motor gives a variable speed system extremely silent (Absence of
typical PWM whistle) and uniform, from zero to the maximum motor rounds. The application of
controlled diodes on the power part gives reliability against extravoltages or over-currents. In addition,
it is possible to adjust the acceleration/deceleration ramp upon the application needs; the controlled
acceleration ramp works for moving braking loads or irreversible systems only.
Drive code 119/92 gives the possibility to control the speed/torque of the Rowan single-phase motor;
the torque regulation can be done by limiting the maximum voltage on the motor through internal
trimmer P1 or, externally, through potentiometer or 0/+10Vdc signal; for a more precise control of the
motor torque, it is necessary to let the code 119/92 communicate with other devices working at current
closed loop (ex. code 199/92 or code 268).
