CAUTION The information of this manual is merely a guide for proper installation. Mitsubishi Electric cannot assume responsibility for the compliance or the noncompliance to any code, national, local, or otherwise for the proper installation of this equipment.
Features The safety stop function of the Mitsubishi Electric FR-D800(-E) inverter can be used to prevent the inverter from supplying rotational energy to motors. Dual input terminals S1 and S2 can be used to cut off the gate-drive power to the IGBT.
Refer ISO/IEC 13849-2. Installation The safety stop function of the Mitsubishi Electric FR-D800(-E) inverter should be used under the following conditions and environment. Table 2 Conditions and environment for using the safety stop function...

WS0-CPU0 Safety I/O combined module WS0-XTIO Figure 5 Safety system example of the FR-D800(-E) inverter NOTE • When starting up the system operation, press the RESET switch to reset the safety stop function first. • In the above configuration, after resetting the emergency stop button, the inverter will be in the safe-state until the RESET switch is pressed.
TEST AND CHECKING FAILURE CAUTION To avoid system faults, check the safety stop function at least once per year. Also, check the safety stop function at system installation, any software changes, and parameter setting changes. I/O status and inverter operation The inverter’s safety related I/O status obeys the following truth table.
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.
