46.04 MOT PHASE LOSS
Selects how the drive reacts when a motor phase loss is detected.
(0) NO
(1) FAULT
46.05 EARTH FAULT
Selects how the drive reacts when an earth fault or current unbalance is detected in the motor or the
motor cable.
(0) NO

46.06 SUPPL PHS LOSS
Selects how the drive reacts when a supply phase loss is detected.
(0) NO
(1) FAULT
46.07 STO DIAGNOSTIC
Selects how the drive reacts when the drive detects that the Safe Torque Off function is active while
the drive is stopped. The Safe Torque Off function disables the control voltage of the power
semiconductors of the drive output stage, thus preventing the inverter from generating the voltage
required to rotate the motor. For Safe Torque Off wiring, see the appropriate hardware manual.
Note: This parameter is only for supervision. The Safe Torque Off function can activate, even when
this parameter selection is NO.
Note: Fault STO 1 LOST / STO 2 LOST is activated if safety circuit signal 1/2 is lost when the drive is
at stopped state and this parameter is set to
(1) FAULT
(2) ALARM
(3) NO
Drive trips on LOCAL CTRL LOSS fault.
The drive generates alarm LOCAL CTRL LOSS and sets the speed to
the speed defined by parameter
WARNING! Make sure that it is safe to continue operation in
case of a communication break.
The drive generates alarm LOCAL CTRL LOSS and freezes the
speed to the level the drive was operating at. The speed is determined
by the average speed over the previous 10 seconds.
WARNING! Make sure that it is safe to continue operation in
case of a communication break.
