Safe Stopping Action
(1) This action is executed only if the axis tag transitions due to a requested STO, not if it was triggered by another safe-stop function (SS1, for example).

Inverter Behavior

For the single-axis inverters and dual-axis inverters, only selected exceptions are
configurable. In the drive behavior tables, the controlling attribute is given for
programmable fault actions.

(1) Ramped Decel is available only when General>Axis Configuration is set to Velocity Loop or Frequency Control.
(2) When configured for Frequency Control (induction motors only), select Decel & Disable only when the Current Limiting feature is
enabled. For more information on this feature, see
Actions define the drive behavior in response to specific conditions. The
Actions category includes Standard Actions and Safety Actions.
Table 143 - Actions Definitions
Action Trigger Condition
Execution of an MSF motion instruction.
Loss of the motion connection (for example, inhibiting the module or a
network cable disconnect).
Receiving MTR OVERLOAD fault.
Receiving INV OVERLOAD fault.
Transition from logic 0 to 1 of the SafeTorqueOffActiveStatus axis tag,
which indicates a safe torque-off action was commanded (STO).
Transition from logic 0 to 1 of the SS1ActiveStatus or SS2ActiveStatus axis
tag which indicates a safe stopping action was commanded (SS1, SS2).
Standard Actions
When a controller connection loss (NODE FLT 06) occurs, it is possible with
firmware revision 9.xxx that other node faults can occur first, triggering a fault
action of Current Decel & Disable. Without knowing if NODE FLT 06 will
occur first on a connection loss fault, we recommend that you do not change
the default connection loss setting of Current Decel & Disable.
TIP Use DLR ring topology (see
where the possibility of connection loss must be minimized.
