Parameters 109
Fault The drive trips on fault 3381 Output phase loss . 1
31.20 Earth fault Selects how the drive reacts when an earth (ground) fault or
current unbalance is detected in the motor or the motor cable. Fault
No action No action taken. 0
Warning The drive generates an A2B3 Earth leakage warning. 1
Fault The drive trips on fault 2330 Earth leakage . 2
31.21 Supply phase loss Selects how the drive reacts when a supply phase loss is
detected. Fault
No action No action taken. 0
Fault The drive trips on fault 3130 Input phase loss . 1
31.22 STO indication
run/stop Selects which indications are given when one or both Safe
torque off (STO) signals are switched off or lost. The
indications also depend on whether the drive is running or
stopped when this occurs.
The tables at each selection below show the indications
generated with that particular setting.
Notes:
• This parameter does not affect the operation of the STO
function itself. The STO function will operate regardless of
the setting of this parameter: a running drive will stop upon
removal of one or both STO signals, and will not start until
both STO signals are restored and all faults reset.
• The loss of only one STO signal always generates a fault
as it is interpreted as a malfunction.
For more information on the STO, see chapter The Safe
torque off function in the Hardware manual of the drive.
