Programming
The index character is used to indicate whether
the command in question is a read or write
command. For a read command, the index
must have the following format:
VLT 8000 AQUA has two parameters for which a text
can be written: parameters 533 and 534 Display text,
see the description of these under the parameter
description. In order to write a text via the PWE block,
the parameter command (AK) must be set to ’F’ Hex.
For a write command, the index must have
the following format:
Data types supported by the frequency converter
Datatype Description
3Integer16
4Integer32
5 Unsigned 8
6 Unsigned 16
7 Unsigned 32
9Textstring
Unsigned means there is no sign included
in the telegram.
E
xample - Write a parameter value:
Parameter 202 Output frequency high limit, f
MAX
is to
be changed to 100 Hz. This value must be remember
after a power failure, so it is written in EEPROM.
PKE = E0CA Hex - Write to parameter 202
Output frequency high limit, f
MAX
IND = 0000 Hex
PWE
HIGH
= 0000 Hex
PWE
LOW
03E8 Hex - Data value 1000,
correspondingto100Hz,see
Conversion.
The reply from the slave to the master will be:
Example - Choice of a data value:
kW [20] is to be selected in parameter 415 Process
units. This value must be remembered after a power
failure, so it is written in EEPROM.
PKE = E19F Hex - Write to parameter 415
Process units
IND = 0000 Hex
PWE
HIGH
= 0000 Hex
PWE
LOW
0014 Hex - Choose data choice kW
[20]
Svaret fra slaven til masteren vil være:
Example - Read a parameter value:
The value in parameter 206 Ramp-up time is required.
The master sends the following inquiry:
PKE = 10CE Hex - read parameter 206
Ramp-up time
IND = 0000 Hex
PWE
HIGH
=0000Hex
PWE
LOW
0000 Hex
If the parameter value in parameter 206 Ramp-up
time is 10 seconds, the reply from the slave to
the master will be as follows:
