__ Software Reference __
Reads a parameter
res = GET par
par = parameter identification
res = parameter value
Reads the value of a parameter, a MCO 305 parameter, or an application para-
meter.
Parameters are addressed with a code, for example KPROP for the Proportional
Factor, or POSERR for the Tolerated Position Error. A complete list of the codes can
be found in the Parameter Reference.
Application parameters are addressed with a number of group 19-**. See also the
parameter reference for details.

Reads a VLT parameter
res = GETVLT par
par = parameter number
res = parameter value
GETVLT reads parameters and return the corresponding value. Thus, with GETVLT
you have access to the operating data (e.g. motor current 1-24) or to the configu-
rations (e.g. max. reference par. 3-03) of the FC 300.
Since only integer values are transmitted, it is necessary to take the conversion
index into consideration when evaluating the return value.
Thus an LCP value of 50.0 Hz (par. 16-13 conversion index = –1) is equivalent to a
return value of 500.
The list of FC 300 parameters with their respective conversion index can be found
in the FC 300 Operating Instructions.
NB!:
Use GETVLTSUB to read parameters with index numbers, for example FC 300
parameter 5-40.
