Outline
Mitsubishi Electric FR-E800-SCE general-purpose inverters have safety functions to stop the output to motors.
By connecting the inverter with a programmable controller with an Ethernet cable, signal input via communication is
enabled.
Wiring
The following describes terminals related to safety monitoring functions.
