OPI variable Meaning
aaTravelDist Total traverse path:
sum of all set position changes in MCS
aaTravelTime Total travel time:
sum of IPO clock cycles from set position changes in MCS
(solution: 1 IPO clock cycle)
aaTravelCount Total travel count:
a complete machine axis trip is defined by the following succession of
states, as based on set position: standstill > traversing > standstill
aaTravelDistHS
Total traversing distance at high axis velocities
aaTravelTimeHS
Total traversing time at high axis velocities
aaTravelCountHS
Total number of traversing operations at high axis velocities
aaJerkTotal Total sum of axis jerks:
Sum of all jerk setpoints in [m/s
aaJerkTime Total travel time with jerk:
sum of IPO clock cycles from jerk setpoint changes in [s] (solution: 1
IPO clock cycle)
aaJerkCount Total number of traversing operations with jerk
