Introduction

Honeywell 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 Honeywell NXL drive equipped with control I/O boards NXLOPTAA, NXLOPTAI,
NXOPTB_ or NXOPTC_. Honeywell NXL HVAC series already includes I/O board NXLOPTAI as
standard.
All other sizes but MF2 have an internal brake chopper. For closer information, contact Honeywell
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.
