Maintenance and diagnostics

The STO function or the STO input/output terminals do not need any maintenance.

The following table shows faults that may be generated by the software that monitors the hardware
related to the STO safety function. If you detect any failure in safety functions, including STO, contact
your local VACON

supplier.

NOTE!

See Table 36 for detailed fault code descriptions.

If any service or repair has to be conducted on the drive installed, please inspect the
checklist given in Table 49.

During maintenance breaks, or in case of service/repair,

ALWAYS

make sure that the

STO function is available and fully functional by testing it.
