such as OFF ON OFF as shown in Figure 6-2-1.
When releasing the trip status, set the operation command to OFF. When the operation command is set to ON,
check that operation starts after resetting.
If the cause of tripping is Er1, reset the error and initialize data. If the drive is not reset, contact GE Fuji.

he drive suddenly restarts

ing the trip status,
