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.
Table 115 - Configurable Stopping Actions
Actions define the drive behavior in response to specific conditions. The
Actions category includes Standard Actions and Safety Actions.
Table 116 - Actions Definitions
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.
See
on
for the Axis Properties>Actions category dialog
box.
Stopping Action
Description
Ramped Decel & Hold
(1)
(1) Ramped Decel is available only when General>Axis Configuration is set to Velocity Loop or Frequency Control.
Most control
The best available stopping action is the one that maintains
the most control over the motor. However, not all faults
support every stopping action.
Current Decel & Hold
Most control
Ramped Decel & Disable
Less control
Current Decel & Disable
Less control
Disable & Coast

(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
Current Limiting for Frequency Control

Safety
Safe Torque Off Action
Transition from logic 0 to 1 of the SafeTorqueOffActiveStatus axis tag,
which indicates a safe torque-off action was commanded (STO).
(1)
• Ramped Decel & Disable
• Current Decel & Disable
• Disable & Coast
Safe Stopping Action
Transition from logic 0 to 1 of the SS1ActiveStatus or SS2ActiveStatus axis
tag which indicates a safe stopping action was commanded (SS1, SS2).
• Ramped Decel
• Current Decel
(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).
