(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 116 - 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

The Connection Loss Stopping Action determines the stopping action to

apply to the motor when a motion controller connection loss is detected (for

example, inhibiting the module or a network cable disconnect). Each

supported stopping action initiates the associated stopping sequence.
