High-function General-purpose Inverter RX2 Series User’s Manual
Parameter
This function is enabled by setting 033 [EXT] as an input terminal function. When a signal connected to
the applicable terminal changes, an error [E012] occurs.
Use this function when you want to trip the inverter via an error (trip) signal generated by a peripheral
system.
Precautions for Correct Use
• When the inverter trips with error code [E12] displayed, the trip is not reset even if the error
signal from the external equipment is reset (EXT terminal is turned off). To reset the trip, Per-
form the reset operation or turn the power off and on again.
• If you reset the inverter while the terminal [EXT] is turned on, [E012] will occur again.
• After the reset, the inverter follows [bb-41] Restart after reset. See 7-5-6 Restart after Releas-
ing Reset on page 7-74.
• When the terminal [EXT] is turned on, an error will occur even if the inverter output is turned
off, and the inverter trips with [E012] displayed.
