Introduction
Vacon NXL is a compact frequency converter with the output ranging from 250 W to 30 kW.
The Motor and Application Control Block is based on microprocessor software. The 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 Vacon 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. For closer information, contact the
or your local distributor (see back cover). The input EMC filters are available as
options externally for MF2 and MF3. In other sizes the filters are internal and included as standard.
