Acceleration / deceleration reference frequency
•
When the output frequency of the inverter is accelerated from 0Hz to01-09, the required time is defined as “accel-
eration time”.
•
When the output frequency of the inverter is decelerated from 0Hz to 01-09, the required time is defined as “decel-
eration time”.

1. S pattern acceleration /deceleration curve 1 is used when acceleration/deceleration is required for a short time until a high-
speed area equal to or higher than thebase frequency, such as for the main shaft of the machine.
2. S pattern acceleration / deceleration curve 2 can effectively reduce motor vibration during the acceleration / deceleration, and
thus prevent the belts and gears from broken.
3. S pattern acceleration / deceleration curve 3 is used to start the inverter gradually without impact.
4. Please refer to Section 5.2.10 The second function for the second acceleration/deceleration time.
5. When RT is “on”, the second function is valid. 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 03-00~03-06, 03-09
for function selection and purposes of the multi-function digital input terminal. For related wiring, please refer to Section 3.3.
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 inadequate since the
output voltage of the inverter is inadequate. In this case, the output voltage can be elevated by properly setting the
torque boost (01-10), and thus a better starting torque can be acquired.
Torque boost
•
If 01-10=6% and 01-04=220V, and when output frequency of the inverter is 0.2Hz, the output voltage is:
•
If RT is “on,” “the second torque boost” on 01-24 is valid (Note 2).
ote:
N
1. If the set value of 01-10 is too high, it will activate current inverter protection or the activation will be impeded.
2. Please refer to Section 5.2.10 for the second torque boost.
3. RT mentioned in this section is the function name of the “multi-function digital input terminal”. Please refer to 03-00~03-06,
03-09 for function selection and purposes of the multi-function digital input terminal. For related wiring, please refer to Section
3.3.
