aaEsrEnable (C, SEMA)

$AA_ESR_ENABLE[Achse]

ESR axis enable

(Axial) enabling of reactions of "Extended Stop and Retract" function.

The selected axial ESR reaction must be parameterized in MD $MA_ESR_REACTION.

beforehand. The corresponding Stop or Retract reactions can be activated via

$AN_ESR_TRIGGER (or for individual drives in the event of communications failure/

DC-link undervoltage), generator-mode operation is automatically activated in response to

aaEsrStat (C, SEMA)

$AA_ESR_STAT[Achse]

ESR axis status

(Axial) status checkback signals of "Extended Stop and Retract" function,

which can be applied as input signals for the gating logic of the ESR (synchronous actions).

Return value

The data is bit-coded. Individual states can therefore be masked or

evaluated separately if necessary:

Bit0 = 1: Generator mode is activated

Bit1 = 1: Retract operation is activated

Bit2 = 1: Stop operation is activated

Bit3 = 1: Risk of undervoltage (DC-link voltage monitoring,

voltage has dropped below warning threshold)

Bit4 = 1: Speed has dropped below minimum generator mode threshold (i.e. no more

regenerative rotation energy is available).

Each slave axis currently coupled via master-slave delivers the machine axis number of the corresponding master axis.

Zero is displayed as default for inactive coupling.

A master axis also shows default value zero.

Return value

refPtStatus (C, SEMA)

Axis must be referenced and is referenced

Identifier indicating whether an axis requires referencing and is referenced.

Note regarding exchange axes:

An exchange axis need only ever be referenced in the channel to which it is currently assigned. A referenced exchange axis is

thus logged onto the channel in which it is traversing with value "3" (requires referencing and referenced) and in other channels

with value "1" (does not require referencing, but referenced).

Return value

Set bits have the following meanings:

Bit0: current measuring system has been referenced

Bit1: current measuring system requires referencing
