Fuji Electric ALPHA5 Smart - PA1_20 to 23 Easy Tuning Settings; PA1_25 to 26 Max. Rotation Speed

CHAPTER 4 PARAMETER
4-20
Basic Parameters
4
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.

Enter the maximum rotation speed of the servomotor for position, speed and torque control.
There is a difference of about 100 r/min between the reference value and actual servomotor rotation
speed under torque control.
Use PA1_96 (speed limit gain for torque control) to adjust the error.
