Current detection
dead-zone width
during speed search
On speed calculation, the motor
speed is calculated from the
detected current value. For cur-
rent detection, the dead-zone
must be set. Set the dead-zone
width using the current detec-
tion resolution as reference
amount. (only for a excitation
search)
Decrease the set value if the
search speed becomes
extremely slow at the speed
search after the motor has been
baseblocked for a long time of
period such as the speed search
at startup.

Min. baseblock time Sets the Inverter's minimum
baseblock time in units of one
second, when the Inverter is
restarted after power loss ride-
through.
Sets the time to approximately
0.7 times the motor secondary
circuit time constant.
When an overcurrent or over-
voltage occurs when starting a
speed search or DC injection
braking, increase the set values.
