* 1. The factory setting will change when the control method is changed. (Open-loop vector control 1 factory settings are given.)
* 2. Factory settings depend on Inverter capacity. (The values shown are for a 200 V Class Inverter for 0.4 kW.)

Speed search
operating cur-
rent (current
detection)
Sets the speed search operation cur-
rent as a percentage, taking the
Inverter rated current as 100%.
Not usually necessary to set. When
restarting is not possible with the
factory settings, reduce the value.

Sets the contactor operating delay
time when there is a contactor on
the output side of the Inverter.
When a speed search is performed
after recovering from a momentary
power loss, the search operation is
delayed by the time set here.

Sets the Inverter's minimum base-
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.
When an overcurrent or overvolt-
age occurs when starting a speed
search or DC injection braking,
increase the set values.
