KEB Deceleration Time (11-47)
(1) When 11-47=0, KEB function is disabled.
(2) Set 11-47 (KEB deceleration time) from 0.0 to 25.5.
KEB Detection Level (11-48）
If the DC-bus voltage falls below the value set in 11-48, the KEB is activated and the inverter starts
decelerating according to the value set in 11-47. To accelerate back to the original output frequency
one of the digital inputs (03-00 to 03-07) set for 48 (KEB acceleration) has to be activated and the
DC voltage has to rise above 11-48 + delta V (Delta V = +10V for 230V series, Delta V = +20 V for
400V Series), refer to the example in figure 4.3.95.

11- 55 STOP Key Selection
Range
【0】：Stop key is disabled when the operation command is not provided
by operator
【1】：Stop key is enabled when the operation command is not provided
by operator
This function can enable or disable the stop key of keypad display when 00-02=1 (external terminal)
or 00-02=3 (communication).
11-55= 0：Stop botton disabled.
11-55= 1：Stop botton enabled.
11- 59 Gain of Preventing Oscillation
Range 【0.00~2.50】
It is used to adjust preventing oscillation function.
If the oscillation in driving motor occurs at normal duty, it is required to increase the
setting value gradually in the unit of 0.01.
11- 60 Upper Limit of Preventing Oscillation
Range
【0~100】%
It is required to limit the preventing oscillation upper limit within the setting value.
