Pa1_20 To 23 Easy Tuning Settings; Pa1_25 To 26 Max. Rotation Speed - Fuji Electric ALPHA5 Smart User Manual

CHAPTER 4 PARAMETER
What is positioning and settling time
Time from completion of issuance of command frequency to issuance of in-position signal
The time varies according to various conditions such as the frequency matching the traveling
distance, acceleration/deceleration rate, and stopping accuracy. Adjustment of the entire system
including the host and servo to optimum conditions is necessary to reduce the positioning and
settling time.
