Chapter 4 Running
4.1 Trial running with no load
The goal of trial running is confirming the following items that are correct or not:
z The servo driver power supply wiring;
z The servomotor wiring;
z The encoder wiring;
z The running direction and the servomotor speed.
4.1.1 Wiring and inspection
Before turn on the power supply, confirms the servomotor:
z The servomotor has no loading on the shaft; decoupling from the machinery if already coupled.
z Because the servomotor has an impact during acceleration or deceleration, therefore the servomotor must be
fixed.
Follow the wiring chart, inspects the following items before turning on the power supply:
z The wirings are correct or not. In particular, L1, L2, L3 wirings and U, V, W wirings corresponding to the
servomotor U, V, W are correct or not.
z The input voltage is correct or not.
z The encoder cable connection is correct or not.
