Graphical Representation

Inputs

Input	Data type	Description
Execute	BOOL	Value range: FALSE, TRUE. Default value: FALSE. A rising edge of the input Execute starts the function block. The function block continues execution and the output Busy is set to TRUE. A rising edge at the input Execute is ignored while the function block is being executed.
Acceleration	DINT	Value range: 0...9999 Default value: 30 Unit: 0.1 s. Example: With a value of 30, 3 seconds are required to accelerate from 0 to the nominal frequency of the motor. It must be possible to reach the value with the available torque of the motor.
Deceleration	DINT	Value range: 0...9999 Default value: 30 Unit: 0.1 s. Example: With a value of 30, 3 seconds are required to decelerate from the nominal frequency of the motor to 0. It must be possible to reach the value with the available torque of the motor.

Input

Data type

Description

Execute

BOOL

Value range: FALSE, TRUE.

Default value: FALSE.

A rising edge of the input Execute starts the function block. The function block continues execution and the output Busy is set to TRUE.

A rising edge at the input Execute is ignored while the function block is being executed.

Acceleration

DINT

Value range: 0...9999

Default value: 30

Unit: 0.1 s.

Example:

With a value of 30, 3 seconds are required to accelerate from 0 to the nominal frequency of the motor. It must be possible to reach the value with the available torque of the motor.

Deceleration

DINT

Value range: 0...9999

Default value: 30

Unit: 0.1 s.

Example:

With a value of 30, 3 seconds are required to decelerate from the nominal frequency of the motor to 0. It must be possible to reach the value with the available torque of the motor.

Outputs

Output	Data type	Description
Done	BOOL	Value range: FALSE, TRUE. Default value: FALSE. FALSE: Execution has not been started, or an error has been detected. TRUE: Execution terminated without an error detected.
Busy	BOOL	Value range: FALSE, TRUE. Default value: FALSE. FALSE: Function block is not being executed. TRUE: Function block is being executed.
Error	BOOL	Value range: FALSE, TRUE. Default value: FALSE. FALSE: Execution of the function block is running, no error has been detected. TRUE: An error has been detected in the execution of the function block.
ErrorID	WORD	Returns the value of a diagnostic code. Refer to Library Diagnostic Codes. If the value is 0 and if the output Error of this function block is set to TRUE, then the diagnostic code can be read with the output AxisErrorID of the function block MC_ReadAxisError.

Inputs/Outputs

Input/Output	Data type	Description
Axis	Axis_Ref	Reference to the axis (instance) for which the function block is to be executed (corresponds to the name of the axis). The name of the axis must be defined in the EcoStruxure Machine Expert Devices tree.
