These tables list the faults, fault codes, and display text for each fault. You can
view these faults by accessing the P67 [Fault Status] parameter.
Table 17 - Safe State Faults
Code Display Text Description
0 Combined Flt A combined fault is indicated if any error has occurred.
1 Critical Flt A nonrecoverable microprocessor error has occurred.
2 Invalid Cfg 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 159 .
3 MP Out Flt An MP Output fault occurs if an error is detected in the Motion Power command to the drive. If you are not using the Di0 digital
input on the drive’s main control board as a ‘hardware enable’, verify that J1 ENABLE jumper, also on the drive’s main control
board, is installed
4 Reset PwrUp 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.
5 Fbk 1 Flt 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.
6 Fbk 2 Flt 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.
7 Dual Fbk Spd 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.
8 Dual Fbk Pos A Dual Feedback Position fault occurs if a discrepancy is detected between the relative position change of the encoder 1 and the
relative position change of encoder 2 since the last SS Reset.
13 Mov in Stop If the safety option is configured for a stop type that includes stopped speed checking, a Mov in 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
27 Fbk 1 V Fault An Encoder 1 Voltage fault occurs if the encoder voltage at encoder 1 is detected as out of range.
28 Fbk 2 V Fault An Encoder 2 Voltage fault occurs if the encoder voltage at encoder 2 is detected as out of range.

Code Display Text Description
11 Decel Flt A Deceleration fault occurs if the speed is detected at greater than the limit specified for the configured Stop Delay [Max Stop
Time] when the configured Safe Stop Type is Safe Stop 1 or 2.
12 Stop Spd Flt A Stop Speed fault occurs when the safety option is configured for a Safe Stop Type 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 [Max Stop Time].
