4-2 Function Mode External Trip •This function trips the Inverter via an error (trip) signal from a peripheral system. To use this function, allocate "12" (EXT) to any of multi-function inputs 1 to 8 (C001 to C008). Note: Do not turn on the EXT terminal after shutting off the power. Otherwise, the Inverter may not store data correctly. 4 •When the EXT terminal is turned on, E12 is displayed and the Inverter trips to stop output. •When the Inverter has tripped, indicating E12, the trip is not reset even if the error signal from external equipment is reset (EXT terminal is turned off). To reset the trip, perform the reset operation or turn the power off and on again.
Functions Power Recovery Restart Prevention Function RUN commands FW, RV EXT terminal Motor rpm RS terminal Alarm output terminal •This function trips the Inverter, displaying "E13", if the power is turned on with the RUN command to the Inverter turned on. •To reset a trip, perform the reset operation, or turn off the RUN command. (Example 1) •If a trip is reset with the RUN command input turned on, the Inverter restarts operation immediately after the trip is reset. (Example 2) •If the RUN command is turned on after the power is turned on, the Inverter operates normally. (Example 3) •Allocate 13 (USP) to any of multi-function inputs 1 to 8 (C001 to C008).
