Self-Diagnostic Test; Operation Check Procedure; Safety Parameters Of Fr-D800 - Mitsubishi Electric Fr-D800 Instruction Manual

NOTE
• The response time from safety stop signal input to drive shutoff (safe state) is faster than 4 ms.
• Hold the ON or OFF status for 2 ms or longer to input signal to terminal S1 or S2.
Signal input shorter than 2 ms is not recognized.
Diagnostic
If a failure is detected, the FR-D800 inverter outputs a fault signal and 'E.SAF' is indicated at the display.
When the FR-D800 inverter outputs a fault signal, take following actions.
1) Check that the input signal logic is the same between S1-PC and S2-PC. If these are different, correct the input signal and
reset the FR-D800 inverter.
2) Disconnect the wires from terminals S1, S2, and PC, 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-D800 inverter. When 'E.SAF' is indicated and a fault
signal is output, a fault may be occurring in the FR-D800 inverter.
Self diagnostic test
The FR-D800 inverter has the self-diagnostic test function at power-ON.
If the FR-D800 inverter outputs a fault signal (SA, E.SAF) at power-ON, take the action described above.
Operation check procedure
Check the operation of the safety stop function as follows.
1) Change and check the I/O state between S1-PC and S2-PC shown in Table 6.
2) If the inverter operation differs from the one shown in Table 6, the FR-D800 may have a fault.
3) If the inverter operates as described in Table 6, check the system performance. Press the emergency switch, press the
start/restart button while a failure is detected (SO-SOC opened), and so on.
4) Finally clear the fault history of the FR-D800 inverter (see the Instruction Manual (Maintenance) for how to clear the fault
history).
