Parameters 245
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 the
Hardware
manual
of the drive.
