VLT

6000 HVAC

143MG.60.B1.02 - VLT is a registered Danfoss trade mark

★ = factory setting. ( ) = display text [ ] = value for use in communication via serial communication port

Programming

Function:

With these parameters, it is possible to see up to 20

saved values (data logs) - [1] being the most recent

and [20] the oldest log. When a start command has

been given, a new entry to the data log is made every

160 ms. If there is a trip or if the motor has stopped,

the 20 latest data log entries will be saved and the

values will be visible in the display. This is useful, e.g.

in the case of service after a trip.

The data log number is given in square brackets; [1]

Data logs [1]-[20] can be read by first pressing

[CHANGE DATA], followed by the [+/-] keys to change

data log numbers.

Parameters 606-614 Data log can also be read out via

the serial communication port.

Data log: Digital input

This is where the latest log data are shown in decimal

code, representing the status of the digital inputs.

Translated into binary code, terminal 16 corresponds

to the bit to the extreme left and to decimal code 128.

Terminal 33 corresponds to the bit to the extreme

right and to decimal code 1.

The table can be used, e.g., for converting a decimal

number into a binary code. For example, digital 40

corresponds to binary 00101000. The nearest smaller

decimal number is 32, corresponding to a signal on

terminal 18. 40-32 = 8, corresponds to the signal on

terminal 27.

Data log: Control wordData log: Control word

Data log: Control word

This is where the latest log data are given in decimal

code for the control word of the VLT frequency

converter.

The control word read can only be changed via serial

communication.

The control work is read as a decimal number which

is to be converted into hex.

See the control word profile under the section Serial

communication in the Design Guide.
