| (57) System for linking and coordinated operation of electronically controlled motors,
said system comprising at least two motors each provided with a motor control unit
consisting of
a) a motor-electronics unit (1) for controlling the motor (2) and for providing measurement
data for motor-control purposes,
b) a microprocessor circuit (3) for governing the control of the motor (2) via the
motor-electronics unit (1), said microprocessor circuit (3) basing its governing of
the control on said measurement data,
c) memory circuits (4), e.g. in the form of RAM, ROM, E-PROM, E2-Prom etc. for containing a program and data for the microprocessor circuit (3) to
carry out said governing of the control, and
d) facility for connecting a keyboard (5) and a display (6) for programming-in of
the desired control procedure providing a desired characteristic curve for the output
provided by the motor.
The microprocessor circuit (3) is additionally connected to a communication interface
(7,8) capable of being used for linking control-wise the at least two electronically
controlled motors to provide in common the desired characteristic curve for the output
provided by the motors.
