You may also perform profiled position corrections in the electronic gearing mode. Suppose, for example,
that you need to advance the slave 10 counts. Simply command:
IP ,10 Specify an incremental position movement of 10 on B axis.
Under these conditions, this IP command is equivalent to:
PR,10 Specify position relative movement of 10 on B axis
BGB Begin motion on B axis
Often the correction is quite large. Such requirements are common when synchronizing cutting
knives or conveyor belts.
Synchronize two conveyor belts with trapezoidal velocity correction :
Instruction Interpretation
GA,A Define A as the master axis for B.
GR,2 Set gear ratio 2:1 for B
PR,300 Specify correction distance
SP,5000 Specify correction speed
AC,100000 Specify correction acceleration
DC,100000 Specify correction deceleration
BGB Start correction
