FieldBus
Structure that allows communication between different devices; are connection lines on which the
digital information is transferred from one or more sources to one or more destinations. Their aim
is therefore to reduce the number of interconnections required. The bus techniques are of great
importance in microprocessor systems but it is necessary to regulate this flow of data in order to
allow for a single communication at a time by disabling other possible data sources at that
moment.
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
Hyperface
Fully digital, synchronous two-way, multi-channel protocol to transfer position information and speed
that requires minimal wiring between 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 several axes with independent transmission.
R
Rectifier
Circuit that converts an AC voltage into a DC voltage.
Regolator P
Regulating circuit functioning in a purely proportional manner.
Regolator PI
Control circuit running in a proportional and integral way.
Regolator PID
Proportional adjustment circuit functioning, integral and derivative way
Reset
Restart the microprocessor.
Braking resistor
When the motor decelerates, a braking resistor converts the kinetic energy of the motor
into heat. The braking resistor is automatically connected to the DC bus voltage when the
bus voltage exceeds its threshold and intervenes in the braking circuita.
RS232
Very common standard hardware for the transmission of signals with the same voltage
level. Suitable for low transmission rates and limited distances.
S
Serial Communication
Transmission based on sending each signal at different times.
Shield
Devices designed to reduce electromagnetic emissions.
Servodrive
Drive that operates the regulation of torque, speed and position of a servomotor.
Safety
All necessary measures to avoid damage to property or to persons.
Soft-start
Circuit for limiting the power from the network to the system during the power up
Stiffness
Capacity of a mechanical system to withstand the stresses or disorders that are applied
from outside.
STO
Safe Torque Off: protection against unexpected restart. The STO function safely interrupts the
power supply to the motor.
