5 DATA USED FOR POSITIONING CONTROL
Example of setting for " Pr. 50 Setting for the movement amount after near-point dog ON"
Assuming that the " Pr. 8 Speed limit value" is set to 200 kpulse/s, " Pr. 46 OPR speed" to 10 kpulse/s,
" Pr. 47 Creep speed" to 1 kpulse/s, and deceleration time to 300 ms, the minimum value of " Pr. 50 Setting for the
movement amount after near-point dog ON" is calculated as follows:
[Machine OPR operation]
Speed limit value: Vp=200kpulse/s
Pr.8
Pr.46
OPR speed:
Vz=10kpulse/s
Actual deceleration time:t = Tb
