￭ Warnings and faults
DescriptionAux. codeFaultWarning
Warning: Current calibration is done at the next start.Current calibration2281A2A1
Fault: Output phase current measurement fault.
The output current is more than the internal limit. This can
also be caused by an earth fault or phase loss.
Overcurrent2310-
A load unbalance that is typically caused by an earth fault in
the motor or the motor cable.
Earth leakage2330A2B3
There is a short-circuit in the motor or the motor cable.Short circuit2340A2B4
The intermediate DC circuit voltage oscillates due to missing
input power line phase.

Safe torque off (STO)
The drive has a Safe torque off (STO) function in accordance with IEC/EN 61800-5-2.
It can be used, for example, as the final actuator device of safety circuits that stop
the drive in case of danger (such as an emergency stop circuit).
When activated, the STO function disables the control voltage of the power
semiconductors of the drive output stage, thus preventing the drive from generating
the torque required to rotate the motor. The control program generates an indication
as defined by parameter 31.22. If the motor is running when STO is activated, it coasts
to a stop. Closing the activation switch deactivates STO. Any faults generated must
be reset before restarting.
The STO function has a redundant architecture, that is, both channels must be used
in the safety function implementation. The safety data given is calculated for redundant
use, and does not apply if both channels are not used.
