13.7.1 Drive-independent responses to ESR
Function
Independent drive reactions are defined axially, that is, if activated each drive processes its
stop and retract request independently. There is no interpolatory coupling of axes or coupling
adhering to the path at stop/retract, the reference to the axes is time-controlled.
During and after execution of drive-independent reactions, the respective drive no longer
follows the NC enables or NC travel commands. Power OFF/Power ON is necessary.
Alarm "26110: Drive-independent stop/retract triggered" indicates this.
Parameters
Generator operation
The generator operation is
• configured: via MD 37500: 10
• enabled: system variable $AA_ESR_ENABLE
• activated: depending on the setting of the drive machine data when the voltage in the DC
link falls below the value.
Retract (drive-independent)
The drive-independent retract is
• configured: via MD 37500: 11; time specification and retract velocity are set in MD; see
"Example: Using the drive-independent reaction" at the end of this chapter,
• enabled: system variable $AA_ESR_ENABLE
• triggered: system variable $AN_ESR_TRIGGER.
Stop (independent drive)
Independent drive stop is
• configured: via MD 37500: 12 and time specified via MD;
• enabled ($AA_ESR_ENABLE) and
• started: system variable $AN_ESR_TRIGGER.
