2.5.4 Safety communication function (Safety communication model)
This function is not available for the standard model and the Ethernet model.
l 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.
Terminal symbol Terminal function description
SX1
Terminal functions can be selected using Pr.S051 SX1/SX2 terminal function selection.
