46.06 SUPPL PHS LOSS FW block: FAULT FUNCTIONS (see above)
Selects how the drive reacts when a supply phase loss is detected. This parameter is only used with
an AC supply.
(0) No No reaction.
(1) Fault Drive trips on SUPPLY PHASE fault.
46.07 STO DIAGNOSTIC FW block: FAULT FUNCTIONS (see above)
Selects how the drive reacts when it detects the absence of one or both Safe Torque Off (STO)
signals.
Note: This parameter is for supervision only. The Safe Torque Off function can activate even when
this parameter is set to (3) No.
For general information on the Safe Torque Off function, see the Hardware Manual of the drive and
Application guide - Safe torque off function for ACSM1, ACS850 and ACQ810 drives (3AFE68929814
[English]).
(1) Fault The drive trips on SAFE TORQUE OFF when one or both of the STO
signals are lost.
(2) Alarm Drive running
:
The drive trips on SAFE TORQUE OFF when one or both of the STO
signals is lost.
Drive stopped
:
The drive generates a SAFE TORQUE OFF alarm if both STO signals
are absent. If only one of the signals is lost, the drive trips on STO1
LOST or STO2 LOST.
(3) No Drive running
:
The drive trips on SAFE TORQUE OFF when one or both of the STO
signals is lost.
Drive stopped

No action if both STO signals are absent. If only one of the signals is
lost, the drive trips on STO1 LOST or STO2 LOST.
(4) Only Alarm The drive generates a SAFE TORQUE OFF alarm if both STO signals
are absent. If only one of the signals is lost, the drive trips on STO1
LOST or STO2 LOST.
46.08 CROSS CONNECTION FW block: FAULT FUNCTIONS (see above)
Selects how the drive reacts to incorrect input power and motor cable connection (ie, input power
