5.9 Menu 91 - Fast Access Parameters
The parameters in this menu are Second Processor virtual parameters which provide a
faster update rate or enhanced resolution than drive parameters.
This parameter enables the short-cut parameters detailed later in this section. You must
set the appropriate bit in this parameter. See the following table.
Sets the speed reference in units of
0.001RPM. This value is mirrored in drive Pr 01.21
(preset speed 1), therefore in order to control the drive speed with this parameter
ensure preset speed 1 is selected on the drive (Pr
01.14=3, Pr 01.15=1).
Ensure bit 0 of Pr
91.01 is set and the full-scale speed in Pr 91.05 is set accordingly
when using this parameter
Controls the hard-speed reference on the drive in units of
0.001RPM.
Ensure bit 1 of Pr
91.01 is set and the full-scale speed in Pr 91.05 is set accordingly
when using this parameter. Note that this parameter is valid only in Closed Loop Vector
and Servo modes only.
