A fault is a condition that stops the drive. There are two fault types.
Type Fault Description
➀
Reserved for future.
➁
Non-Resettable
➂
User Configurable
This type of fault normally requires drive or motor repair. The cause of the fault must be corrected before the fault can be cleared. The fault will be reset on power up after repair.
These faults can be enabled/disabled to annunciate or ignore a fault condition.
An alarm is a condition that, if left untreated, may stop the drive. There are two alarm types.
Type Fault Description
➀
User Configurable
➁
Non-Configurable
These alarms can be enabled/disabled through [Alarm Config 1].
These alarms are always enabled.
The condition or state of your drive is constantly monitored. Any changes will be indicated through the LEDs and/or the HIM (if present).
Frame 2 Drive LED Indicators
Status indicators for Frame 2 drives are located near the top and front of the

Accessing Status Indicators of Powered Frame 3A and 3B Complete
Drives
Status indicators (shown in Table 6.A
) for Frame 3A and 3B complete
drives are inside the power module bay. To access the status indicators, follow the instructions below.
!
ATTENTION:
Risk of injury or death exists. Only qualified electricians should use this procedure. Bypassing the interlock mechanism exposes the user to dangerous high voltage live components. Failure to comply can result in personal injury and/ or death.
To Open:
1.
Unlock the input filter bay door and the power module bay door by using the key provided with the drive.
2.
Turn the circuit breaker handle door locking mechanism release with a
flat head screwdriver ( Figure 6.1
) to unlatch the input filter bay door.

3.
Swing open the input filter bay several inches until the door interlock mechanism unlatches from the power module bay door.
4.
Swing open the power module bay door to view the status indicators on the power module(s).
To Close:
1.
Close and lock the power module bay door.
2.
Close and lock the input filter bay door.

Manually Clearing Faults
To manually clear faults, follow these steps.
1.
Press the
Esc
(Escape) key to acknowledge the fault.
The fault information is removed so that you can use the HIM.
2.
Address the condition that caused the fault.
The cause must be corrected before the fault can be cleared.
3.
After corrective action has been taken, clear the fault by using
one
of these methods:
•
Press the
(
Stop) key.
•
Cycle drive power.
•
Set parameter 239 - [Fault Clear] to “1” (Clear Faults).
•
“Clear Faults” on the HIM Diagnostic menu.
Converter Faults
When a fault is generated in the Converter, that fault is passed to the Inverter so all the faults are recorded in the Inverter fault queue. Faults in the converter are numbered 1 to 99.
When using PowerFlex 700 Vector Control, the fault from the Converter is added to a base number of 300, so all the Converter faults are numbered 301 to 399. The pop-up window on the HIM alerts the user to look at the fault log in the PF700AC to get the specific fault text.
- Fault - F 3 40

When using PowerFlex 700S Phase II Control, the faults from the Converter are all combined into one fault code (F110) in the Inverter. The pop-up window on the HIM alerts the user to look at the fault log in the PF700AC to get the specific fault text.

ATTENTION:
Only qualified personnel familiar with adjustable frequency AC drives and associated machinery should plan or implement the installation, start-up, and subsequent maintenance of the system. Failure to comply can result in personal injury and/ or equipment damage.
ATTENTION:
To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged completely before servicing. After removing power to the drive, wait 5 minutes for the bus capacitors to discharge. Measure the DC bus voltage at the
DC+ and DC- TESTPOINT sockets on the front of the power
). The voltage must be zero.
When the door filter of the Input Filter Cabinet requires replacement, remove the dirty filter and replace it with an equivalent clean filter.
Important:
If the CE Shield Barrier has been removed for servicing, it must be reinstalled to restore the casual touch protection this barrier provides.
