Vacon NXL – Perfect choice for motors up to 30kW

The NXL is the trouble-free choice for all open loop applications– The standard unit fulfills the EMC requiremens of both industrial, public

and residential environments– The same unit is suitable for all open loop applications (conveyors,

mixers, fans, pumps, packaging machines, etc.)– No additional cabinet is required, protection classes IP21 and IP54– The instructions to install, connect and program the drive, are

integrated to each unit– High starting torque and dynamics is guaranteed, thanks to

sophisticated open loop vector control and effective design– The motor noise is extremely low because of high switching frequency

(up to 16 kHz, 6 kHz as standard without derating) and close to sinusoidal current

– The standard control I/O can be extended with more inputs and outputs. All typical fieldbus controls are possible by adding the fieldbus boards. The RS485 (Modbus) is integrated as standard.

Vacon NXL – Software

The standard Multi-Control Application includes a large number of possibilities, e.g.:– All control inputs and outputs are programmable– PID controller– PFC for up to four parallel pumps– Flying start– Complete protections– Motor auto-identification– Output relay delays

The PLC possibilities are integrated in the Vacon NXL. It is often possible to remove the PLC and integrate the functions in the NXL software with the Vacon NC1131-3 Engineering tool.Following ready-made special applications are available free of charge:

– Brake control– Lift– Multi-Motor– Sliding Door– Local/Remote– Fire mode– Multi-purpose (June 2006)
