12.7.3.3 Continue interrupted positioning
By setting the control input POS_bRestart to TRUE, an interrupted positioning process can be
continued if the control input POS_bAbort has been reset to FALSE before.
• Distances of a relative positioning that have already been covered are taken into consideration.
• If the continuation of a positioning process via the input POS_bRestart is not possible, this is
displayed via bit 11 of the status output POS_dnState.
• If during an active or cancelled positioning process a change-over is effected (e. g. by activating
a quick stop or inhibiting the controller), it is also possible to continue a positioning process via
POS_bRestart, taking the distance that has already been covered into consideration.
• However, after a homing has been carried out again, or after the following machine parameters
have been changed, a continuation of an interrupted positioning process via the control input
POS_bRestart is no longer possible:
• Encoder resolution ( C00100 )
• Position encoder selection ( C00490 ), motor encoder selection ( C00495 )
• Gearbox factors ( C02520 , C02521 , C02522 , C02523 )
• Feed constant ( C02524 )
• Motor mounting direction ( C02527 ), position encoder mounting direction ( C02529 )
• Traversing range ( C02528 )
• Cycle ( C02536 ) for modulo traversing range
• Position control structure ( C02570 )
