To release the trip status, enter the reset command by pressing the reset key or from terminal (RST) after re-
moving the cause of the trip. Since the reset command is an edge operation, be sure to input a command string
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.
! WARNING
1. If alarm reset is activated with operation signal ON, the drive suddenly restarts
which may be hazardous. Be sure to disable the operating signal when releas-
ing the trip status,
otherwise fire could occur.
