Subpoint Details
This section gives a brief overview of each subpoint, including any notable
behavior or settings. Further information may be obtained by referring to the
Toshiba
Q7 Series Operation Manual
and
7-Series Serial Communications
User Manual
. While most of the available objects are predefined, two LAI and
two LDO subpoints are available that can be user-configured to access any
available drive parameters. This allows a customized application to be easily
developed.
10.5.1
LAI Subpoints
#3..........Output frequency in Hz. ASD parameter FD00.
#4..........Load current in % (100% = drive’s rated current). ASD parameter
FE03.
#5..........Output voltage in % (100% = drive’s rated voltage). ASD parameter
FE05.
#6..........Input power consumption (drive + motor) in kW. ASD parameter
FE29.
#7..........System energy consumption (drive + motor) in kWh. ASD parameter
FE69.
#8..........Indicates the signal level currently being applied to the ASD’s RR
analog input terminal. This can be used to monitor such items as
feedback sensor outputs and other process variables. Expressed in
% (100% = input rated value). ASD parameter FE35.
#9..........Similar to #8, this object indicates the signal level currently being
applied to the ASD’s VI/II analog input terminal. ASD parameter
FE36.
#10........Indicates the present fault code. Under normal operation (no faults),
this value will be 0. ASD parameter FC90.
#11........In addition to the predefined LAI subpoints (#3
∼
#10), two user-
defined LAI subpoint are available (#11 and #12). To define which
ASD parameters are to be associated with these LAI’s, enter their
parameter numbers (in decimal) into parameters
Ext Comm Cfg #5
and
Ext Comm Cfg #6
. Parameter
Ext Comm Cfg #5
corresponds to #11 and
Ext Comm Cfg #6
corresponds to #12.
For example, if the drive’s peak current (ASD parameter FE31) is to
be monitored in #11, then convert the parameter number to decimal
(0xFE31 = 65073
10
) and enter the result (65073) into
Ext Comm Cfg
#5
. After cycling power, subpoint #11 will then provide access to
peak current. Note that because any available ASD parameter can
be accessed via this method, subpoints #11 and #12 are
dimensionless and have multiplier values of 1 (i.e. the object’s data
