Parameters 209
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.
