6.2.1 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.
6.2.2 Offline inertia determination
Can be achieved through driver front panel or on Motion Studio
Please make sure: 1. Servo driver is disabled.
2. Axis is within safe and allowed range and limit switch is not triggered
