Vacon VACON® NXL Drive

Details

The VACON® NXL drive has reached the Limited phase of its lifecycle and is no longer in active production. Danfoss offers an extensive portfolio of low-voltage drives and will help you select the optimal replacement drive for your application.

The standard I/O of the Vacon NXL has been optimized for typical

control requirements. In addition to digital and analog inputs

and outputs, RS485 is included as standard. All inputs and

outputs of the standard I/O and option boards are freely programmable.

Both Analog Inputs can be programmed for 0...10 V

or 0(4)...20 mA signals. Analog Input can also be programmed

as Digital Input.

The standard I/O can easily and cost-effectively be extended

with OPT-AA or OPT-AI boards, if necessary. The OPT-AA is the

most effective way to add one more Relay Output, and the OPTAI

is normally used when galvanically isolated motor thermistor

connection is needed. These boards are installed in option

board slot E.

It is also possible to control the Vacon NXL with various kinds of

fi eldbuses with OPT-C-type boards (see the table below). The

I/O extension and fi eldbus boards are the same for all Vacon NX

products. The fi eldbus boards can be installed in slot D or E.

There are a large number of OPT-B-type option boards available.

The most typical boards are included in the table below. It

is possible, for instance, to add three more output relays with

OPT-B5, if necessary. The OPT-B-type boards are typically installed

in slot E.
