IO DATA DESCRIPTION
11.1 VACON
®
Control Word - FBFixedControlWord
The VACON
®
Control Word is composed of 32 bits. This control data is split into two words:
FBFixedControlWord consist of the first 16 bits and FBGeneralControlWord consist of the remaining
16 bits.
While functionality of the FBFixedControlWord is fixed in VACON
®
standard applications,
functionality of the FBGeneralControlWord is totally application specific and can vary even in
VACON
®
standard applications.
FBFixedControlWord bit definitions are described in the table below. Note that there are some
control word bit modifications in VACON
®
NXP AC drive. These modifications are described in
Table 207. Unused bits have to be set to zero.
