If you are using a specific software suite (like or Alta Control ) where "v 15.0.2" refers to a firmware version, check the Cisco Bug Search Tool or the Alta Release Notes to see if "Speed Search" refers to a new UI search optimization or performance feature.
To ensure the drive catches the motor smoothly without tripping an overcurrent fault, adjust the search sensitivity: Speed searchВ Control v 15.0.2
Set b3-01 (Speed Search Selection) to 1 (Enabled) . If you are using a specific software suite
Ensure your control method (e.g., V/f Control or Open Loop Vector) supports Speed Search, as some high-precision flux vector modes require specific PG feedback tuning to work. Typically set between 100% and 150% of the
Typically set between 100% and 150% of the motor's rated current. This determines how much "effort" the drive uses to find the frequency.
Set the time the drive takes to "search" down from the maximum frequency. A default of 2.0 seconds is common. 3. Verification & Safety
To prepare or enable the feature in a control system (such as Yaskawa or similar VFD controllers ), follow these general configuration steps: 1. Enable the Speed Search Function
