Operation check for the
safety stop function
After completing the work for "4. Setting up", be sure to perform the self-diagnostic test
of the safety stop function and operation check.
If the operation check is not performed, the safety stop function may not operate
properly.
For details of the safety stop function, refer to the Safety Stop Function Instruction
Manual (BCN-A23228-001) contained in the enclosed CD-ROM.
Self diagnostic test
The FR-A800/F800 inverter has the self-diagnostic test function at power-ON.
If the FR-A800/F800 inverter outputs a fault signal (SA, E.SAF) at power-ON, take the
action described below.
Diagnostic
If a failure is detected, the FR-A800/F800 inverter outputs a fault signal and 'E.SAF' is
indicated at the display. When the FR-A800/F800 inverter outputs a fault signal, take
following actions.
If the inverter outputs the fault signal, observe the following procedure.
1) Check that the input signal logic is the same between S1-SIC and S2-SIC. If these
are different, correct the input signal and reset the FR-A800/F800 inverter.
2) Disconnect the wires from terminals S1, S2, and SIC, then reset or turn OFF and ON
the power. If the 'SA' is indicated on the operation panel, there is a failure in the system
except for the FR-A800/F800 inverter. When 'E.SAF' is indicated and a fault signal is
output, a fault may be occurring in the FR-A800/F800 inverter
Operation check procedure
Check the operation of the safety stop function as follows.
1) Change and check the I/O state between S1-SIC and S2-SIC shown in the following
matrix of the safety relared signals.
2) If the inverter operation differs from the one shown in the matrix, the FR-A800/F800
may have a fault.
3) If the inverter operates as described in the matrix, check the system performance.
Press the emergency switch, press the start/restart button while a failure is detected
(So(SO)-SOC opened), and so on.
4) Finally clear the faults history of the FR-A800/F800 inverter (see the Instruction
Manual for how to clear the faults history).
The FR-A800/F800 inverter's safety related I/O status obeys the following matrix.
