8.7.2 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.
Error Classifi- Description
code cation
0xFF80 Fault STO activated while the servo
drive was enabled, or an
attempt to enable the servo
drive was made while STO
was active.
0xFF81 Safety Servo drive internal diagnostic
fault fault.
0xFF85 Safety Internal STO supply on the
fault power card is not within
limits.

8.9 Commissioning Test

NOTICE
Perform a commissioning test after installation of the STO function, after every change to the installed function, or after
a safety fault (described in chapter 8.7.2 Error Codes). Perform the test for each STO line.
There are 2 ways to implement the commissioning test depending on the method used to program the PLC, however the
steps of the test are the same:
•
Using the Danfoss Library or the TwinCAT
•
Bit-wise readout of the status.
Commissioning test using libraries
Depending on the application, 1 or both of the following libraries are required to program the commissioning test:
•
Danfoss Library
-
MC_ReadAxisInfo_ISD51x
- MC_ReadStatus_ISD51x
- MC_ReadAxisError_ISD51x
-
MC_Reset_ISD51x
•
®
TwinCAT Library
- MC_ReadStatus
- MC_ReadAxisError
- MC_Reset
Test steps
1 Run the application (all the
servo drives are enabled).
2 Stop the application.
3 Disable all the servo drives.

Operating Instructions
Error code 0xFF80 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.
Error code 0xFF81 means that there is a fault on the servo

drive that can only be reset by carrying out a power cycle.
Complete the commissioning test as described in

PLC.
Operation of the ISD 510 servo system can only be
resumed if the test is completed successfully. If error code
0xFF81 or 0xFF85 is issued again, contact Danfoss Service.
