SPX Advanced application – monitoring values
SPX ADVANCED APPLICATION MANUAL SVCH0203—October 2017 www.eaton.com
3.2.1 Monitoring values 2
V7.24.1 Current A ID 1113
Unfiltered motor current, recommended signal
for NCDrive monitoring.
Drive Synch Operation Master drive:
This value is the total current of the system
divided by number of drives in the system
(SbLastID). SbLastId cannot be changed; it
needs to be set according to how many drives
are linked with system bus.
Drive Synch Operation Follower drive:
This value is current of drive own power unit.
V7.24.2 Torque % ID 1125
Unfiltered motor torque.
V7.24.3 DC Voltage V ID 44
Unfiltered DC link voltage.
V7.24.4 Application status word ID 43
“status word 1”
Application status word combines different
drive statuses to one data word.
Recommended signal for NCDrive monitoring.
Application status word 1 ID43
False True
b0 Flux not ready Flux ready (>90 %)
b1 Not in ready state Ready
b2 Not running Running
b3 No fault Fault
b4 Direction forward Direction reverse
b5 Emergency stop active Emergency stop NOT active
b6 Run disabled Run enable
b7 No warning Warning
b8 Power positive Power negative or Gen torque or
current limit active

to actual encoder frequency with 0,001 Hz
accuracy. Can be used for speed control tuning
in closed loop control.
V7.24.16 Actual power factor ID 68
Estimated power factor value.
V7.24.17 Flux current ID 72

Function Comment
b0 Fault status Logger is triggered when there is
a fault
b1 Warning status Logger is triggered when there is a
warning
b2 Auto reset warning Logger is triggered when there is
a fault that has been dened to be
automatically reset. This bit can be
used to get the rst fault situation.
b3 Fault status OR warning status B0 OR B1 triggering situation has
happened
