7 Troubleshooting
Fault Codes, Causes and Possible Solutions
Faults are detected for drive protection, and cause the drive to stop while triggering the fault output terminal
MA-MB-MC. Remove the cause of the fault and manually clear the fault before attempting to run the drive again.
Alarm Codes, Causes and Possible Solutions (alarm)
Alarms are drive protection functions that do not necessarily cause the drive to stop. Once the cause of an alarm is
removed, the drive will return to the same status as before the alarm occurred.
When an alarm has been triggered, the ALM light on the digital operator display blinks and the alarm code display
flashes. If a multi-function output is set for an alarm, that output terminal will be triggered for certain alarms.
Note: If a multi-function output is set to close when an alarm occurs, it will also close when maintenance periods are reached,
triggering drive hardware alarms.
oPE Codes, Causes and Possible Solutions (programming error)
An Operator Programming Error (oPE) occurs when a contradictory parameter is set or an individual parameter is set to
an inappropriate value.
The drive will not operate until the parameter or parameters causing the problem are set correctly. An oPE, however, does
not trigger an alarm or fault output. If an oPE occurs, investigate the cause and refer to Table 20 for the appropriate
action. When an oPE appears on the operator display, go to oPE Flt Parameter (F2) to see which parameter is causing the
oPE.
Auto-Tuning Codes, Causes and Possible Solutions (auto-tune)
Auto-Tuning faults in this section are displayed on the digital operator and will cause the motor to coast to a stop.
Auto-Tuning faults do not trigger a multi-function digital output set for fault or alarm output.
An End error on the digital operator display indicates Auto-Tuning has successfully completed with discrepancies in the
calculations. Check the cause of the End error using the tables in this section and perform Auto-Tuning again after fixing
the cause.
The drive may be used in the application if no cause can be identified despite the existence of an End error.
An Er error indicates that Auto-Tuning has not completed successfully. Check for the cause of the error using the tables
in this section, and perform Auto-Tuning again after fixing the cause.
Table 2 0 lists the corrective action that can be taken when an error occurs.

bb
Baseblock Alarm
Drive output interrupted as indicated by
an external baseblock signal.
External baseblock signal was entered via one of the multi-function input
terminals (S1 to S8).
• Check external sequence and baseblock signal input timing.
• Verify that one of the logic input terminals in the C2 sub-menu is not
programmed incorrectly to “Ext BaseBlk N.O.” or “Ext BaseBlk N.C.”.
• Verify that the logic input is being triggered correctly when the drive is
running.

DB Overload Flt
DB Overload Alm
The braking transistor has reached its
overload level.
The wrong braking resistor is installed.
• Make sure the rating of the braking resistor fits drive and application. Use
an external braking transistor if necessary.
