Safety Communication Function (Safety Communication Model) - Mitsubishi Electric 800 Series Instruction Manual

2.6.8 Safety communication function (Safety
communication model)
This function is not available for the standard model and the Ethernet model.
 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
SX1
Terminal functions can be selected using Pr.S051 SX1/SX2 terminal function selection.
SX2
SY1
Terminal functions can be selected using Pr.S055 SY1/SY2 terminal function selection.
SY2
Connect this terminal to the power supply common terminal of a transistor output (open collector
output) device, such as a programmable controller, in the source logic to avoid malfunction by
SD
undesirable current.
Common terminal for the 24 VDC power supply (terminal PC). Isolated from terminal 5.
Common terminal for SX1 and SX2.
PC
Can be used as a 24 VDC 0.1 A power supply.
SC1
Common terminal for SY1 and SY2.
SC2
