Test And Checking Failure - Mitsubishi Electric 700 Series Instruction Manual

Inverter connection
Do not connect the FR-D700 (sink logic) together with the FR-D700-SC (source logic). If connected
together, the safety stop function does not work properly.

4. Test and checking failure

 systematic
To avoid
check the correct function of the monitor signal. This test shall be carried out at system installation, any software
changes, parameterization changes, and/or at least once per year.
I/O status and failure
FR-D700-SC safety related I/O status obeys the following truth table.
Input power S1-SC
OFF -
Short
ON Open
Short
Open
*1 At an internal safety circuit fault, one of E.SAF or E.CPU is displayed on the operation panel. SA is displayed on the operation
panel while S1 and S2 signals are both open and the safety function operates (without internal safety circuit fault).
*2 To use RUN terminal for monitor output of failure detection, Pr.190 should be set 81 (Safety monitor 2).
In case of diagnostic or functionality test, check the I/O state whether it is same or not as Table.5.
Diagnostic
If the failure detected, FR-D700-SC output alarm signal and indicate 'E.SAF' at the display.
In case of FR-D700-SC output the alarm, please take following action.
(1) Check the S1-SC and S2-SC input signal logic is the same. If these are different logic, correct the input
signal and reset the FR-D700-SC.
(2) Disconnect the wire from S1, S2, SC terminal, then reset or power-off and on, If the 'SA' letter is
flashed up at display, there is failure in system except FR-D700-SC. But, still 'E.SAF' is displayed and
alarm output, there is malfunction on FR-D700-SC.
Self diagnostic test
FR-D700-SC does the self-diagnostic test on the power-ON.
If FR-D700-SC output alarm at power-ON, please take the action described in 'Diagnostic' at above.
