Setting For The Movement Amount After Near-Point Dog On; Opr Acceleration Time Selection - Mitsubishi Electric QD77MS User Manual

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 kPLS/s, " Pr. 46 OPR speed" to 10 kPLS/s,
" Pr. 47 Creep speed" to 1 kPLS/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:
[OPR operation]
Speed limit value: Vp=200 kPLS/s
Pr.8
Pr.46 OPR speed:
Vz=10 kPLS/s
Actual deceleration time: t = Tb
[Pr.50] Setting for the movement amount after near-point dog ON
When using the count method 1) or 2), set the movement amount to the OP after
the near-point dog signal turns ON.
(The movement amount after near-point dog ON should be equal to or greater
than the sum of the "distance covered by the deceleration from the OPR speed to
the creep speed" and "distance of movement in 10 ms at the OPR speed".)
