Positioning Commands
Commands for the absolute and relative positioning of the axis. (Group ABS and REL)
Command Description Syntax Parameter
Absolute Positioning (ABS)
ACC Sets acceleration ACC a a = acceleration
DEC Sets deceleration DEC a a = deceleration
POSA Positions axis absolutely POSA p p = position in UU
VEL Sets velocity for relative and absolute
motions and set maximum allowed
velocity for synchronizing. VEL v v = scaled velocity value
Relative Positioning (REL)
ACC Sets acceleration ACC a a = acceleration
DEC Sets deceleration DEC a a = deceleration
POSR Positioning relative to the actual position. POSR d d = distance to actual position in
UU
VEL Sets velocity VEL v v = scaled velocity value
†
Synchronizing Commands
Commands to synchronize the slave with the master or the master simulation. (Group SYN)
Command Description Syntax Parameter
DEF SYNCORIGIN Defines master-slave relation for the
next SYNCP or SYNCM command
DEF SYNCORIGIN
master slave master = reference position in qc
slave = reference position
MOVE
SYNCORIGIN Relative shifting of the origin of
synchronization MOVE SYNCORIGIN
mvalue mvalue = Relative offset
PULSACC Sets acceleration for master simulation PULSACC a a = acceleration in Hz/s
PULSVEL Sets velocity for master simulation PULSVEL v v = velocity in pulses per second
(Hz)
SYNCV Synchronization of velocity SYNCV –
SYNCP Synchronization of angle/position SYNCP –
SYNCM Synchronization of angle/position with
marker correction SYNCM –
SYNCSTAT Queries flag for synchronization status res = SYNCSTAT
SYNCSTATCLR Resetting of the flags MERR and MHIT SYNCSTATCLR value value =
8 = SYNCMMHIT
16 = SYNCSMHIT
32 = SYNCMMERR
64 = SYNCSMERR
