Explanation of important definitions / abbreviations
analogue input
analogue signal source which can be connected to the terminal block (voltage, current,
potentiometer)
analogue output
analogue signal output on the terminal block (voltage / current)
breakpoint
point of a curve where it changes some of its characters (e.g. slope)
CAN bus
system bus (for master/slave connections)
control
the output frequency refers to the reference signal value of the control process
counter
internal counter that can be operated with digital or virtual input
DC brake
braking with leading a DC voltage to the terminals of the motor
default
factory setting according to the most frequent user demands
digital input
permits logic commands to be activated (e.g. start, direction, counter, program etc.)
digital output
freely programmable built-in relay (or optocoupler)
direction
command for changing the direction of rotation
error signal
the signed difference of the reference signal and the feedback signal
f hold
inhibition of the frequency change
feedback signal
the measured back value at control
fmax
maximum frequency
fmin
minimum frequency
forced cooling
refers to the motor (the motor is cooled with a fixed ventilator mounted on it)
IRE reception
incremental rotation speed signal transmitter interface circuit
jog
command for starting at a low frequency (e.g. for adjustment of the machinery).
master / slave
controlling unit / subordinated unit
memory 1-3
storage places for the user settings in the frequency converter
MOD bus
standard RS485 protocol used to remote control and supervision.
modification
the regulation or control is extended so that an external element can change the actual
reference signal through an analogue or digital input
modifying signal
at regulation or control it modifies the value of the reference signal
motor potentiometer
changing the analogue signal with digital signals (up and down)
n
rotation speed of the motor
n IRE
rotation speed measured by the incremental rotation speed encoder
operation mode
main menu for setting the main operation conditions at programming
own cooling
refers to the motor (the motor is cooled by its own blower)
Pconsumed
wattage consumption from the power line
PID data
they contain the parameters applied for the regulation process
PID extension
controlling 1 unit, and operating further fix units with the digital outputs
position control
this control operates the motor until it is in the proper position according to the signal
transmitter
potentiometer
signal source with own supply voltage connected to the analogue input
productivity
data of the technology process (to be defined along with dimension by the user)
program
operating according to preset parameters
program activation
starting mode of programs written to the programmable digital inputs
