5.2.2 Manually setting acceleration/deceleration time
Set acceleration time from 0 (Hz) operation frequency to maximum frequency HJ and deceleration time as the time
when operation frequency goes from maximum frequency HJ to 0 (Hz).

Title Function Adjustment range Default setting
CEE Acceleration time 1 [Note]~ sec.
According to
model
FGE Deceleration time 1 [Note]~ sec.
According to
model
Note:The minimum setting of acceleration and deceleration times have been set respectively at 0.1 sec. by default, but
they can be changed within a range of 0.01 sec. (setting range:0.01~600.0 sec.) by changing the setting of the
parameter V[R (default setting).
⇒ For details, refer to Section 5.20.
+ If the programmed value is shorter than the optimum acceleration/deceleration time determined by load conditions,
overcurrent stall or overvoltage stall function may make the acceleration/deceleration time longer than the
programmed time. If an even shorter acceleration/deceleration time is programmed, there may be an overcurrent
trip or overvoltage trip for inverter protection.
⇒ For details, refer to Section 13.1.
5.3 Increasing starting torque
CW : Automatic torque boost

Note: Parameter displays on the right always return to after resetting. The previous setting is displayed on the
left.
Ex.
•Function
Simultaneously switches inverter output V/f control and programs motor constants automatically
(auto-tuning function 1) to improve torque generated by the motor. This parameter integrates the
setting of special V/f control selection such as automatic torque boost or vector control.

Note: Square reduction torque control, sensor vector control (optional), etc. can be selected using the V/f
control mode selection parameter RV.
