■ GETVLT
GETVLT reads VLT parameters and return the corres-
ponding value. Thus, with GETVLT you have access
to the operating data (e.g. motor current P520) or to
the configurations (e.g. max. command value P205)
of the VLT.
Since only integer values are transmitted, it is ne-
cessary to take the conversion index into conside-
ration when evaluating the return value.
Thus an LCP value of 50.0 Hz (conversion index =
–1) is equivalent to a return value of 500.
The list of VLT parameters with their respective
conversion index can be found in the VLT5000 and
VLT5000 Flux operating instructions.
Summary
Reads a VLT parameter
Syntax
res = GETVLT par
NB!
Use GETVLTSUB to read parameters with
index numbers, e.g. VLT parameter 606…617.
Parameter
par = parameter number
Return value
res = parameter value
Command group
PAR
Cross Index
SETVLT
Syntax-Example
PRINT GETVLT 202
/* reads parameter 202 output frequency high */

■ GETVLTSUB
GETVLTSUB reads VLT parameters with index num-
bers, e.g. VLT parameter 606…617, and return the
corresponding value.
Since only integer values are transmitted, it is ne-
cessary to take the conversion index into conside-
ration when evaluating the return value.
Thus an LCP value of 50.0 Hz (conversion index
= –1) is equivalent to a return value of 500.
The list of VLT parameters with their respective con-
version index can be found in the VLT5000 and
VLT5000 Flux operating instructions.
Summary
Reads a VLT parameter with index number
Syntax
res = GETVLTSUB par indxno
Parameter
par = parameter number
indxno = index number
Return value
res = parameter value
Portability
With option card version 5.00 onwards.
Command group
PAR
Cross Index
SETVLTSUB
Syntax example
PRINT GETVLTSUB 25 1
// reads index 1 of the Quick menu parameter
// (VLT5000Flux only)
