Safety Parameters Of Fr-E800(-E) - Mitsubishi Electric 800 Series 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-E800(-E) inverter outputs a fault signal and 'E.SAF' is indicated at the display.
When the FR-E800(-E) 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-E800(-E) 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-E800(-E) inverter. When 'E.SAF' is indicated and a
fault signal is output, a fault may be occurring in the FR-E800(-E) inverter.
Self diagnostic test
The FR-E800(-E) inverter has the self-diagnostic test function at power-ON.
If the FR-E800(-E) 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-E800(-E) 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-E800(-E) inverter (see the Instruction Manual for how to clear the fault history).
