Object Details
This section gives a brief overview of each object, 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 analog
input and two analog output objects are available that can be user-configured
to access any available drive parameters. This allows a customized
application to be easily developed.

Analog Input Objects
AI #1..... Output frequency in Hz. ASD parameter FD00.
AI #2..... Load current in % (100% = drive’s rated current). ASD parameter
FE03.
AI #3..... Output voltage in % (100% = drive’s rated voltage). ASD parameter
FE05.
AI #4..... Input power consumption (drive + motor) in kW. ASD parameter
FE29.
AI #5..... System energy consumption (drive + motor) in kWh. ASD parameter
FE69.
AI #6..... 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.
AI #7..... Similar to AI #6, this object indicates the signal level currently being
applied to the ASD’s VI/II analog input terminal. ASD parameter
FE36.
AI #8..... Indicates the present fault code. Under normal operation (no faults),
this value will be 0. ASD parameter FC90.
AI #9..... In addition to the predefined analog input objects (AI #1
∼
AI #8), two
user-defined AI objects are available (AI #9 and AI #10). To define
which ASD parameters are to be associated with these AI’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 AI #9 and
Ext Comm Cfg #6
corresponds to AI #10.
For example, if the drive’s peak current (ASD parameter FE31) is to
be monitored in AI #9, then convert the parameter number to decimal
(0xFE31 = 65073
10
) and enter the result (65073) into
Ext Comm Cfg
#5
. After cycling power, AI #9 will then provide access to peak
current. Note that because any available ASD parameter can be
accessed via this method, AI #9 and AI #10 are dimensionless and
