Parameters 275
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.
• This parameter cannot be changed while the drive is
running.
For more information on the STO, see the
Hardware manual
