3 GENERAL INFORMATION
This manual presents information necessary for the configuration of all the functions and parameters of the frequency
inverter. This manual must be used together with the user's manual.
The text provides additional information so as simplify the use and programming of the frequency inverter in certain
applications.
It is prohibited the reproduction of the contents of this manual, in whole or in part, without the written permission

3.1 TERMINOLOGY AND DEFINITIONS

3.1.1 Terms and Definitions Used
Amp, A: Ampère.
AIP: analog input via potenciometer.
AIx: analog input "x".
AOx: analog output "x".
◦
C: Celsius degrees.
CA: alternate current.
CC: direct current.
Pre-Charge Circuit: charges the capacitors of the DC link with limited current, avoiding current peaks in the
inverter power-up.
CO/DN/PB/ETH: Interface CANopen, DeviceNet, ProfibusDP or Ethernet.
CV: cavalo-vapor = 736 Watts (Brazilian unit of measurement of power, normally used to indicate mechanical power
of electric motors).
Heatsink: metal part designed to dissipate the heat produced by power semiconductors.
DIx: digital input "x".
DOx: digital output "x".
Switching Frequency: switching frequency of the IGBTs of the inverter bridge, normally expressed in kHz.
Run/Stop: inverter function which, when activated (run), accelerates the motor by acceleration ramp up to the
reference frequency and, when deactivated (stop), decelerates the motor by deceleration ramp. It may be controlled
by digital input set for this function, via serial or via SoftPLC.
h: hour; time unit.
General Enable: when activated, it accelerates the motor by acceleration ramp and Run/Stop = Run. When
disabled, the PWM pulses will be immediately blocked. It may be controlled by digital input set for this function, via
serial or via SoftPLC.
HMI: human-machine interface; device which allows controlling the motor, viewing and changing the inverter
parameters. It features keys to control the motor, navigation keys and graphic LCD display.
hp: horse power = 746 Watts (power unit, normally used to indicate mechanical power of electric motors).
Hz: hertz; frequency unit.
IGBT: insulated gate bipolar transistor - basic component part of the output inverter bridge. It works as an electronic
switch in the saturated (closed switch) and cut-off (open switch) modes.
I : inverter rated current by P295.
nom
kHz: quilohertz = 1000 Hertz; frequency unit.
200 V Line: Models powered from 110 to 127 Vac, 200 to 240 Vac or 280 to 340 Vdc, for more information refer
