8.9.1 Error Codes

If bit 3 of the statusword is set, this indicates any faults that occur on the servo drive. If the fault occurred because of the STO circuit,
the cause of the fault can be found in object 0x603F.
Table 24: Error Codes
Error code PROFINET

error code
0xFF80 0x11E
0xFF81 0x11F
0xFF85 0x120
Error code 0xFF80/0x11E can be a normal status of the application. In this case, the servo drive requires a reset signal from the PLC.
To use the STO function in an application that requires a control guard (see ISO 12100 for details), this reset information can be
given automatically by the PLC. All servo drives on the same line will display this fault at the same time. Carry out a check on the PLC
to compare the fault of all servo drives on 1 line.
Error code 0xFF81/0x11F means that there is a fault on the servo drive that can only be reset by carrying out a power cycle. Com-
plete the commissioning test after the power cycle. Operation of the servo system can only be resumed if the test is completed
successfully. If error code 0xFF81/0x11F or 0xFF85/0x120 is issued again, contact Danfoss Service.

8.9.2 Fault Reset

To reset faults, change bit 7 of the controlword from 0 to 1. See the VLT® Servo Drive System ISD 510, DSD 510, MSD 510 (VLT®
Flexmotion ) Programming Guide for further information.
