Chapter 6. Function Description (FUN)
6.4.5 Accel/Decel pattern and time selection
1) FUN_33 (Accel/Decel reference speed)
Acceleration time, deceleration time and BX time is set on the basis of the value at
FUN_33(Accel./decel.
reference speed)
, which is ‘Max speed’or ‘Ref speed’.
(Setting example 1) if FUN_33= “Max Speed”, Max motor speed= 3000rpm and Operating speed= 1500rpm, Accel time=
5 sec, accel time from 0 (stop) to 1500rpm would be 2.5 sec.
(Setting example 2) If FUN_33 is set to ‘Ref Speed’ and speed command and acceleration time is set to 1500rpm and 5
seconds, respectively, it takes 5 seconds to accelerate from the standstill to 1500rpm.
2) FUN_40 ~ 47(Accel/Decel time 1 ~ 4)
Accel/Decel time 1-4 can be set in SV-iV5[MRL] as shown below.
