* 1. The factory setting will change when the control method is changed. The open-loop vector 1 control factory settings are given.
* 2. The factory setting depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given.

Proportional
Sets the proportional gain (PI con-
gain of the
trol) of the speed estimator during
speed estimator
speed search taking the setting of
during speed
N4-08 to be equivalent to a setting
search
of 1.0.
Usually, there is no need to
change this setting. If, however,

voltages occur during the search,
reduce this setting.

Min. baseblock
Sets the Inverter's minimum base-
time
block time in units of one second,
when the Inverter is restarted after
power loss ridethrough.
Sets the time to approximately 0.7
times the motor secondary circuit
time constant.
最小 BB 时间
When an overcurrent or overvolt-
age occurs when starting a speed
search or DC injection braking,
increase the set values.
Voltage recov-
Sets the time required to return

the Inverter output voltage to nor-
mal voltage at the completion of a
speed search, in units of one sec-
ond.
电压恢复时间
Sets the time required to recover
from 0 V to the maximum volt-
age.
