Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
7-10-2 Safety Function Settings
Two dedicated input terminals GS1 and GS2 are used for safety input.
To enable the EDM output (safety monitor output), turn ON the EDM function selector switch. This auto-
matically allocates the Multi-function Output 11 Selection (C021) to 62 (EDM).
EDM Function Selector Switch
ON (EDM)
OFF(Normal)
• When the EDM function selector switch is turned from ON to OFF, the input/output terminals
allocated to EDM are reset to 255 (no: No allocation) and the output operation selection setting keeps
NC contact.
Additional Information
The safety device monitor (62: EDM) turns ON when the inverter detects that both of the GS1
and GS2 input signals turn OFF and shuts off the output. If the EDM output signal does not turn
ON even when the inverter shuts off the output by the safety function, check the GS1 and GS2
input circuits and the EDM detection circuit.

*1. When the EDM function selector switch is ON, these functions are forcibly set and cannot be changed.
*2. The inverter will trip with E37. If this trip occurs simultaneously with the external trip (E12), the emergency shut-
off (E37) has priority, except at power-on.
*3. The safety function cannot ensure safety if either one of the GS1 and GS2 input terminals turns ON during the
inverter trip with E37.
