stored in the encoder. It is compatible with the previous version, EnDat 21,
but offers advantages such as the transfer of other data together with that of
position without a separate request.
EtherCAT Communication protocol implemented on the Ethernet network for the
synchronous transmission of information.
Ethernet High speed data communication network.
F
Filter, EMC Device that reduces noise generated by the power supply cables.
FMEA Failure Mode and Effects Analysis.
Fieldbus An industrial network structure that allows communication between different
devices. The digital information is transferred from one or more sources to one
or more destinations using network topologies like ring, star, daisy chain, etc.,
as defined by the specific fieldbus protocol.
Fuses Overcurrent protection devices
G
Grade of protection
(Protection grade)
Security level of the system components.
Ground Connection of the conductor or the frame to the ground connector.
GUI Graphical User Interface.
H
Hiperface Fully digital, synchronous, two-way, multi-channel protocol to transfer position
information and speed; it requires minimal wiring between the drive and
feedback from the motor (2-wire).
I
IGBT Semiconductor devices for the control of PWM switching..
Interface Fieldbus EtherCAT or CANopen
IFOC (control) Indirect Field Oriented Control
M
Machine Set of mechanical devices, connected to each other of which at least one is in
motion.
Multiaxis system Machine with two or more axes that can be driven/controlled independently.
R
Rectifier Circuit that converts an AC voltage into a DC voltage.
Regulator, P Control circuit functioning in a purely proportional manner.
Regulator, PI Control circuit functioning in a proportional and integral manner.
Regulator, PID Control circuit functioning in a proportional, integral and derivative manner.
Reset Restart the microprocessor.
Resistor, braking When the motor decelerates, a braking resistor converts the kinetic energy of
the motor into heat. The braking resistor automatically intervenes in the
braking circuit when the DC bus voltage exceeds its threshold.
Resolver Analog motor feedback component that detects a change in position of the
shaft and transmits it to the drive for controlling the motor.
RS-232 A common standard that defines the serial transmission of signals with the
same voltage level. Suitable for low transmission rates and limited distances.
