4.3 Drive Monitoring
This section describes the objects used to monitor the drive. Refer to the appropriate Technical Manual for
additional information.
4.3.1 Operating Status – AI1-AI13, BI1-BI8
The following table summarizes the input objects available for monitoring the operating status of the drive.
Operating Variable Object ID Description
Speed Reference AI1 Reports the speed reference as commanded from the source selected by
AO8 (operator, terminal, or network). This allows speed reference to be
monitored even when the network is not the command source.
This value matches AO1 only when the network is selected as the command
source (AO8 = 4,5,6).
Output Speed AI2 Reports output speed.
Output Current AI3 Reports output current.
Output Power AI5 Reports output power. This object is only available on GPD506 drives.
Drive Temperature AI6 Reports drive temperature. This object is only available on GPD506
drives.
AC Output Voltage AI8 Reports AC output voltage (i.e. voltage applied to motor).
DC Bus Voltage AI9 Reports DC bus voltage.
Kilowatt Hour Meter AI4 Reports cumulative drive energy usage in kilowatts. This object is only
available on GPD506 drives.
Megawatt Hour Meter AI13 Reports cumulative drive energy usage in megawatts. This object is only
available on GPD506 drives.
PID Feedback AI7 Reports PID feedback. If PID is disabled, this value will be zero. This
object is only available on GPD506 drives.
Elapsed Timer – Hrs AI11 Reports cumulative run time in hours.
Elapsed Timer – 10K
Hrs
AI12 Reports cumulative run time in increments of 10K hours.
Fault Code AI10 Reports drive fault status. This value is the decimal equivalent of a binary
fault word. It is the sum of the values associated with each fault bit, as listed
below:
Fault
Bit Value
Overcurrent, Ground, Short Circuit 0 1
Overvoltage 1 2
Drive Overload 2 4
Overheat 3 8
Main Circuit 5 32
Brake Transistor 6 64
External 7 128
Hardware 8 256
Motor Overload 9 512
During Undervoltage 11 2048
Power Loss 12 4096
Phase 13 8192
Run Status BI1 Reports the run status (1=Run) as commanded from the source selected by
AO8 (operator, terminal, or network). This allows the status to be monitored
even when the network is not the command source.
This value matches BO1 only when the network is selected as the command
source (AO8 = 6,7,8).
Forward/Reverse
Status
BI2 Reports the forward/reverse status (1=Reverse) as commanded from the
source selected by AO8 (operator, terminal, or network). This allows the
status to be monitored even when the network is not the command source.
This value matches BO2 only when the network is selected as the command
source (AO8 = 6,7,8).
Drive Ready Status BI3 Reports whether or not the drive is ready to accept a run command
(1=Ready).
Fault Status BI4 Reports the drive fault status (1=Fault).
