is larger than the standard value.
3 Check the current loop gain.
(SV009, SV010, SV011, SV012)
4 Disconnect the UVW phase wiring
from the terminal block, and the
cannon plug from the motor. Check
the insulation with a tester.
5 Check the insulation between the
motor power cable and FG.
6 Connect the cannon plug, and check
the insulation between the power
cable and FG.
7 Check if there is any abnormality in
