Set max acceleration/deceleration for velocity command.
If target velocity = x [rpm], max acceleration = a [unit: rpm/ms], acceleration time = t [ms]
Pr3.12 = 1000/a
Pr3.13 = 1000/a
a = x/t
Velocity
(rpm)
For example: If motor is to achieve 1500rpm in 30s, a=1500/30=50rpm/ms
Pr3.12 = 1000/a= 20. Hence when Pr3.12 = 20, motor can achieve 1500rpm in 30s.
1000
(rpm)
Usually used when there is rapid acceleration or trapezoidal wave velocity command due to many different internal
speed segments under velocity control mode which causes instable while motor in motion.
Under velocity control mode, 6083 and 6084 is limited by Pr3.12 and Pr3.13 correspondingly.
