Default

Description

EnableClosed Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set. Both are required for enabling the drive.

BOOL

FALSE, TRUE

N/A

No default

Request to read the error status of the axis.

Axis

AXIS_REF

1, 256

N/A

No default

Name of a declared instance of the AXIS_REF library functionClosed A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances..

Outputs

Description

Valid

BOOL

FALSE, TRUE

N/A

Indicates the AxisErrorID output is valid.

Busy

BOOL

FALSE, TRUE

N/A

Indicates this function block is executing.

Error

BOOL

FALSE, TRUE

N/A

Indicates an invalid input was specified.

ErrorID

INT

-32768 to +32767

 

Indicates the error if Error output is TRUE.

See PLCopen Function Block ErrorIDs.

AxisErrorID

INT

-32768 to +32767

 

Indicates the error status of the axis.

  • Each bit indicates a specific error.
  • Both emergency-stop (E-stop) and controlled-stop (C-stop) errors are indicated.
  • The Output Bits table defines the bits of this output.

Remarks

See Function Blocks - General Rules about how inputs and outputs work.
