These tables list the faults, fault codes, and display text for each fault. You can
view these faults by accessing the [Fault Status] parameter.

Code Display Text Description
SAFE FLT 00... RESERVED Reserved.
SAFE FLT 01... INTERNAL HDWR nn
(1)
A nonrecoverable microprocessor error has occurred.
SAFE FLT 02... INVALID CONFIG An Invalid Configuration fault occurs if a configuration parameter is set to an illegal value or combination of values. See the
Configuration Fault Codes on page 141 .
SAFE FLT 03... MP OUT nn
(1)
An MP Output fault occurs if an internal error is detected in the circuit that removes motion producing power from the drive
terminals.
SAFE FLT 04... RESET AT POWERUP A Reset Powerup fault occurs if the reset type is configured for Manual or Manual Monitored and the Reset_In input is detected
as ON when power is cycled.
SAFE FLT 05... FEEDBACK 1 A Feedback 1 fault occurs if any of these conditions are detected at encoder 1:
• An open wire is detected.
• A short-circuit is detected.
• A sine/cosine fault exists, that is the amplitude of the sine signal squared plus the amplitude of the cosine signal squared is
not equal to a constant value.
• The feedback signals indicate a frequency greater than or equal to 100 kHz for a Sine/cosine encoder or 200 kHz for a
incremental encoder.
• Illegal encoder signal transitions are detected.
• Incorrect Overspeed Response Time setting (refer to
Table 15 on page 47 ).
SAFE FLT 06... FEEDBACK 2 A Feedback 2 fault occurs if any of these conditions are detected at encoder 2:
• Illegal encoder signal transitions are detected.
• The feedback signals indicate a frequency greater than or equal to 200 kHz.
SAFE FLT 07... DUAL FB SPEED A Dual Feedback Speed fault occurs if an error is detected between the speed from the first encoder and the speed from the
second encoder. Valid speed-comparison values are determined by the configured Feedback Speed Ratio and Feedback Speed
Tolerance.
SAFE FLT 08... DUAL FB POSITION A Dual Feedback Position fault occurs if a discrepancy is detected between the relative position change of encoder 1 and the
relative position change of encoder 2 since the last SS Reset.
SAFE FLT 13... MOTION AFTER STOP If the drive is configured for a stop type that includes stopped speed checking, a Motion After Stop fault occurs if either of the
following is detected after the system is stopped and the door has been unlocked:
• Speed greater than the configured Standstill Speed
• A position change greater than the configured Standstill Position limit
SAFE FLT 27... ENCODER 1 VOLTAGE An Encoder 1 Voltage fault occurs if the encoder voltage at encoder 1 is detected as out of range.
SAFE FLT 28... ENCODER 2 VOLTAGE An Encoder 2 Voltage fault occurs if the encoder voltage at encoder 2 is detected as out of range.
SAFE FLT 30... RESERVED Reserved.
SAFE FLT 31... RESERVED Reserved.
(1) The nn field is a sub code that provides additional information regarding the fault.
Code Display Text Description
SAFE FLT 11... DECELERATION A Deceleration fault occurs if the speed is detected at greater than the limit specified for the configured Stop Delay [Maximum
Stop Time] when the configured Stop Category is Safe Stop 1 or 2.
SAFE FLT 12... STOP SPEED A Stop Speed fault occurs when the drive is configured for a Stop Category that includes Standstill Speed checking (Safe Stop 1 or
2, and Safe Torque Off with Standstill Speed Checking) and the detected speed is greater than the configured Standstill Speed at
the end of the configured Stop Delay [Maximum Stop Time].
