# Default value of data element after controller start-up (P-AXIS-00723)

P-AXIS-00723 | Default value of data element after controller start-up
Description | When cyclic communication is used (see P-AXIS-00720), this parameter defines the value of the telegram element after controller start-up. This parameter is also used if reading the current value at the start of motion to fixed stop is not required (see P-AXIS-00730). At the end of the move to fixed stop function, the controller writes this value back to the drive.
Parameter | antr.fixed_stop.drive_ident[i].startup_value
Data type | REAL64
Data range | Dependent on the data type P-AXIS-00722 of the drive object SGN16: MIN(SGN16) ≤ startup_value ≤ MAX(SGN16) SGN32: MIN(SGN32) ≤ startup_value ≤ MAX(SGN32) UNS16: MIN(UNS16) ≤ startup_value ≤ MAX(UNS16) SGN32: MIN(SGN32) ≤ startup_value ≤ MAX(SGN32)

Axis types | T, R
Dimension | T: ---- | R: ----
Default value | 0
drive types. | SERCOS, CANopen
Remarks | This parameter must be assigned if the data item is transferred cyclically, i.e. the parameter P-AXIS-00720 has the value CYCLIC or reading the active parameter value is suppressed, i.e. P-AXIS-00730 has the value 1.
