Action Table
Use the Actions view to setup tasks for the drive to perform based on selected sources and conditions. Up to 32 actions can be configured. Each action, at a minimum, has three elements, of which may have additional requirements.
For example, Action 1 below attempts to Enable Axis 1 any time it sees a on Digital Input 1. This action also has a Source ID setting which digital input to react on and a Task ID setting which axis to enable.
Action Execution
Actions are executed sequentially, top to bottom, starting at Action 1, at a 4kHz rate.
Certain tasks, like clearing faults, may take a longer than 4kHz cycle to execute. These tasks will be initiated in a low priority thread. If the task is triggered a second time while the task is already running, it will not be queued to run again and the action will be ignored until the running task is complete.
Scanning of the table does not begin until boot up has completed. Any edges occurring on any signal will be ignored until this time. In addition, edge triggered actions will not be executed if the test condition is already true at boot time.
To avoid inconsistent behavior, an action is automatically disabled when any of its fields are edited. Reactivate the action after editing any of its field settings.
Chaining Actions
Actions are executed sequentially so they can be configured to execute a chain of actions.
For example, if Action 1 enables axis 1 when mains ready is true, then Action 2 can be configured to start homing when axis 1 is enabled. When Action 1 completes its task, it triggers Action 2 to execute.

| Task |
An action task defines the drive function to execute when the source's condition is met. Some tasks execute a drive function when the condition becomes true. Other tasks execute every cycle and use the condition or source to set a drive value.

Controlled Stop, and stay enabled. While this action is active then bit 1 in AXIS#.MOTIONDISSOURCES will be set. Drive remains enabled while motion stops. CS bit is not set. |

Clear Faults, Edge-triggered
In addition to clearing the fault, this action sets the software enable to prevent the axis from immediately enabling.
See action task 28 to avoid the software enable set.
ACTION#.TASKID selects which axis the faults will be cleared on, zero will clear the faults on both axes.

Clear Faults Software Enable Unchanged, Edge-triggered
This action clears any faults on the axis and will not set the software enable. The axis immediately enables after the fault is cleared when using this action task. When using the AKD2G drive with wired digital inputs,it is convenient to clear faults and not have the drive set the software enable automatically.
See action task 12 for the software enable set when faults are cleared.
ACTION#.TASKID selects which axis the faults will be cleared on, zero clears the faults on both axes.

ACTION#.SOURCE
|
| Source ID |
Some action sources require a specific Source ID number such as a DIN value. |
ACTION#.SOURCEID
|
| Source Param. |
Some sources require source parameters to further specify what is acted on. For example, if the source is Move Complete, the source parameter field becomes editable. Setting this field to 8 specifies the action considers Move Complete for motion task 8 on the selected axis.
|
To Add |
| Condition |
A condition value is required when the condition performs a comparison. For example, if the action source is set to Analog Input, and the condition is set to "Falls Below Threshold", a condition value defines the threshold. If the condition value is set to 4.5, the action checks if the analog input transitions from a value greater than 4.5 volts to a value less than 4.5 volts.
