Online inertia determination
Enable motor using controller. Let motor run at above 400rpm, make sure there are acceleration,
constant velocity and deceleration phase during the whole run. Cycle through 2-3 times to calculate
load-inertia ratio. Result can be found on the front panel d16 or through Motion Studio system
monitoring page. Enter the calculated value into Pr0.04 and save.
Inertia measuring using Motion Studio
1. Start Motion Studio and maneuver to inertia ratio identification page under performance tuning.
Set trial run velocity Pr6.04 and acc-/deceleration time Pr6.25, click on 'Upload' to upload
parameters to servo driver.
2. Tick "Prohibit external enabling" and click on "servo on".
3. Click and hold "CCW" to start the motor. Current position will show motor cycles of revolution.
Click on POS 1 to save current position as starting point. Click and hold "CW" to start the motor
again. Click on POS 2 to save current position as ending point.
4. Set the waiting time between each cycle in Pr6.21 and no. of cycles in Pr6.22. Click on 'Run' and
motor will run according to the parameters set.
5. After the calculation is done, inertia ratio will be calculated automatically and click on 'write' to
enter the calculated value into Pr0.04.
