The information of this manual 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.
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. FR-A800/F800 R/L1 S/L2 T/L3 Logic IGBTs +24V...
A hazard of personal injury and/or equipment damage exists if codes are ignored during installation. CAUTION Ensure the safety relay unit and the FR-A800/F800 unit is mounted closely in enclosure meeting IP54 and all interconnection wiring is short and protected against open and short circuit faults. Refer ISO/ IEC13849-2.
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.

WS0-CPU0 Safety I/O combined module WS0-XTIO Fig.5 Safety system example with FR-A800/F800 NOTE • When starting up the system’s operation, press the RESET switch to reset the safety stop function first. • In the above configuration, after reset of emergency stop button, drive will be in safe-state until RESET switch is pressed.
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.5 Truth table of safety related signals Internal...
3) If there is no different state from Table.5, check the systematic performance, such as, press the emergency switch, press the start/restart button at the failure detected (SO-SOC opened), and so on. 4) Finally clear the error record of the FR-A800/F800 (see the user manual how to clear the error record). SAFETY PARAMETERS OF FR-A800/F800 The safety parameters of FR-A800/F800 are depicted as follows.
