Speed Search (Set Value: 14, 15)
•
The speed search function is provided for smooth restarting without stopping a free running motor.
Use it when switching the motor from a commercial power supply operation to Inverter operation,
when starting with the Inverter a motor turned by external force, and so on.
•
The speed search function searches for the present motor frequency, from high frequency to low.
When the motor’s rotation speed is detected, it is accelerated from that frequency to the frequency
reference according to the acceleration/deceleration time setting.

Note
For 5.5- and 7.5-kW Inverters only, the speed search function can be adjusted by setting parame-
ters n101 (speed search deceleration time) and n102 (speed search operating level). If the speed
search cannot be executed properly using the default setting, lengthen the deceleration time or
lower the operating level. To reduce the speed search time, check with the application while either
shortening the deceleration time or raising the operating level.
