MC_Power

Function block		MC_Power
Enables or disables the operation of an axis.
VAR_IN_OUT
B	AxisIn	AXIS_REF	Reference to an axis.
VAR_INPUT
B	Enable	BOOL	TRUE to enable the axis, FALSE to disable the axis.
E	EnablePositive	BOOL	TRUE to let the axis move into the positive direction.
E	EnableNegative	BOOL	TRUE to let the axis move into the negative direction.
VAR_OUTPUT
B	Status	BOOL	Effective state of the power stage.
E	Valid	BOOL	TRUE if a valid output is available at the function block.
B	Error	BOOL	Signals that an error has occurred within the function block.
E	ErrorID	MC_Error	Error identification.
The Enable input enables the power stage in the drive and not the function block (FB) itself. If the MC_Power FB is called with the Enable = TRUE while being in Disabled, the axis state changes to Standstill. You can use other FB that includes a timer to detect whether the Enable input is TRUE. If the Enable output is FALSE within the time specified (ex: 1 second), an alarm will be triggered. If power fails (also during operation) it will generate a transition to the ErrorStop state. EnablePositive and EnableNegative are both level sensitive. EnablePositive and EnableNegative can both be TRUE. Only 1 FB MC_Power should be sent per axis.
