Accel Jerk  REAL  REAL  Immediate or Tag 
You must always enter values for 
the Accel and Decel Jerk 
operands. This instruction only 
uses the values if the Profile is 
configured as S-curve. 
•  Accel Jerk is the acceleration 
jerk rate for the axis 
•  Decel Jerk is the deceleration 
jerk rate for the axis. 
Use these values to get started. 
•  Accel Jerk = 100 (% of Time) 
•  Decel Jerk = 100 (% of Time) 
•  Jerk units = 2 
Enter the jerk rates in these Jerk 
Units. 
0 = Units per sec
3
 
1 = % of Maximum 
2 = % of Time (use this value to 
get started) 
4 = Units per MasterUnit
3
 
6 = % of Time-Master Driven 
Decel Jerk  REAL  REAL  Immediate or Tag 
Jerk Units  DINT  DINT  Immediate 
Merge  DINT  DINT  Immediate  Do you want to turn all current 
axis motion into a pure jog 
governed by this instruction 
regardless of the motion 
instructions currently in process? 
•  NO — Choose Disabled (0) 
•  YES — Choose Enabled (1) 
Merge Speed  DINT  DINT  Immediate  If Merge is Enabled, which speed 
do you want to jog at? 
•  Speed of this instruction — 
Choose Programmed = 0 
•  Current speed of the axis — 
Choose Current = 1 
Lock Position  REAL  REAL  Immediate or Tag  Position on the Master Axis 
where a Slave should start 
following the master after the 
move has been initiated on the 
Slave Axis. 
See the Structure section below 
for more information. 
Lock Direction  UINT32  UINT32  Immediate or Tag  Specifies the conditions when the 
Lock Position should be used.
