S shape acceleration /deceleration curve 3(01-05(P.29)=“3”)
Please refer to 5.2.12 S pattern time setting.
Acceleration/deceleration time increments
When 01-08(P.21)=0, minimum acceleration / deceleration time (01-06(P.7) 、 01-07(P.8) 、 01-14 (P.16) 、
01-22(P.44)、01-23(P.45)、01-36~01-39(P.255~P.258)、04-35~04-42(P.111~P.118)、10-27~10-28(P.238~P.239)、
10-36~10-37(P.276~P.277)) increment is 0.01s.
When 01-08(P.21)=1, minimum acceleration / deceleration time(01-06(P.7)、01-07(P.8)、01-14(P.16)、01-22(P.44)、
01-23(P.45) 、 01-36~01-39(P.255~P.258) 、 04-35~04-42(P.111~P.118) 、 10-27~10-28(P.238~P.239) 、
10-36~10-37(P.276~P.277)) increment is 0.1s.
Acceleration / deceleration reference frequency
When the output frequency of inverter is accelerated from 0Hz to 01-09(P.20), the required time is defined as
“acceleration time”.
When the output frequency of inverter is decelerated from 0Hz to 01-09(P.20), the required time is defined as
“deceleration time”.
Note: 1. S shape acceleration /deceleration curve 1 is used when acceleration/deceleration is required in a short time in
high-speed area equal to or higher than the base frequency, such as spindle motor.
2. S shape acceleration /deceleration curve 2 can effectively reduce motor vibration during the acceleration /
deceleration, and thus prevent the belts and gears from failing.
3. S shape acceleration /deceleration curve 3 is used to start the inverter gradually without impact.
4. Please refer to Section 5.2.10 second function for the second acceleration/deceleration time.
5. When RT is “on”, the second function is on. For the operation characteristics of the motor, please refer to
Section 5.2.10.RT mentioned in this section is the function name of the “multi-function digital input terminal”.
Please refer to
03-00~03-09(P.80~P.84,P.86,P.126~P.128,P.550),03-25~03-30(P.551~P.556),03-33~03-38(P.559~P.564)
;
Please refer to section 3.7 for wiring.
5.2.4 Torque boost
V/F
For an inverter controlled by V/F mode, when the motor starts up, the starting torque is usually insufficient since the
output voltage of the inverter is low. In this case, the output voltage can be elevated by setting the torque boost
(01-10(P.0)) properly, and thus getting a better starting torque.
