VFD - NXL Carel
4. Technical data
4.1. Introduction
CAREL VFD-NXL is a compact frequency converter with the output ranging from 250 W to 30 kW.
In CAREL VFD-NXL frequency converter the internal microprocessor controls the motor basing on the information it receives through measurements,
parameter settings, control I/O and control keypad. The IGBT Inverter Bridge produces a symmetrical, 3-phase PWM-modulated AC-voltage to the
motor.
The control keypad constitutes a link between the user and the frequency converter. The control keypad is used for parameter setting, reading status
data and giving control commands. Instead of the control keypad, also a PC can be used to control the frequency converter if connected through a
cable and a serial interface adapter (optional equipment).
You can have your CAREL VFD-NXL drive equipped with control I/O boards OPT-AA, OPT-AI, OPT-B_ or OPT-C_.
All other sizes but MF2 have an internal brake chopper.
The input EMC filters are available as options externally for MF2 and MF3. In other sizes the filters are internal and included as standard.
