1 GENERAL DESCRIPTION Features Mitsubishi FR-A800/F800 safety stop function prevents a drive from supplying rotational energy to motors. Dual safety channels ‘S1’ and ‘S2’ cut off the gate-drive power for IGBT to turn off.

2 INSTALLATION AND WIRING CAUTION The following information is merely a guide for proper installation. Mitsubishi Electric Co. cannot assume responsibility for the compliance or the noncompliance to any code, national, local or otherwise for the proper installation of this equipment. A hazard of personal injury and/or equipment damage exists if codes are ignored during installation.
CAUTION In order to meet safety stop, an approved safety relay unit to ISO13849-1 safety category 3 or better shall be used in conjunction with FR-A800/F800 as shown in example. In addition, all other components with in the safety stop loop shall be ‘safety approved’ types. WARNING To avoid an electric shock hazard, insert the magnetic contactor (MC) between power source and drive.

4 TEST AND CHECKING FAILURE CAUTION To avoid systematic faults, a test even for faulty demands of the safety function has to be performed in order to 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-A800/F800 safety related I/O status obeys the following truth table. Table.
Diagnostic If the failure detected, FR-A800/F800 output alarm signal and indicate ‘E.SAF’ at the display. In case of FR-A800/F800 output the alarm, please take following action. 1) Check the S1-SIC and S2-SIC input signal logic is the same. If these are different logic, collect the input signal and reset the FR-A800/F800. 2) Disconnect the wire from S1, S2, SIC terminal, then reset or power-off and on. If the ‘SA’ letter is flashed up at display, there is failure in system except FR-A800/F800.
