When SW method 1 is selected for phase initialization mode, use SMCL tools to adjust st_cg to minimize
the movement when performing phase initialization. Click on SMCL tool button in figure 10.1.1 to open
SMCL tools, as figure 10.3.1. Increase st_cg to decrease the movement during phase initialization. If
st_cg is set to be too large, it may cause vibration and unstable system. Click on Start SMCL button to
check the movement during phase initialization and if there is vibration. Adjust st_cg and execute SMCL
test repeatedly and check position error until the movement during phase initialization is acceptable.
Note:
Do not modify the value in e_pointer field.
