Sets the function to prevent hunting.
0 : Disabled
1 : Enabled (Normal)
Sets the performance of the hunting prevention function. Usually it is not necessary to change this
parameter.
Sets the primary delay time constant of the hunting prevention function. Usually it is not necessary to
change this parameter.
Sets the performance of the hunting prevention function. This parameter adjusts Reverse run. Usually
it is not necessary to change this parameter.
Sets the oscillation suppression function for the DC bus voltage.
0 : Disabled
1 : Enabled
Adjusts the responsiveness of the oscillation suppression function for the DC bus voltage. Set n1-13
= 1 [DC Bus Stabilization Control = Enabled] to enable this parameter.
Sets the amount by which the output frequency is to be lowered during high-slip braking, as a
percentage of E1-04 [Maximum Output Frequency], which represents the 100% value.
Sets the maximum current output during high-slip braking as a percentage, where E2-01 [Motor
Rated Current (FLA)] is 100%. Also sets the current suppression to prevent exceeding drive overload
tolerance.
Sets the dwell time, a length of time when high-slip braking is ending and during which the motor
speed decreases and runs at a stable speed. For a set length of time, the drive will hold the actual
output frequency at the minimum output frequency set in E1-09.
Sets the time used to detect oL7 [High Slip Braking Overload], which occurs when the output
frequency does not change during high-slip braking. Usually it is not necessary to change this
parameter.
Sets the gain value that the drive multiplies by the V/f pattern output value during overexcitation
deceleration to calculate the overexcitation level.
Sets the upper limit of the current that is suppressed at the time of overexcitation deceleration as a
percentage of the drive rated current.
Sets the direction of motor rotation where the drive will enable overexcitation.
0 : Disabled
1 : Enabled Only when Rotating FWD
2 : Enabled Only when Rotating REV
