Item
■For the NZ2FT-GN
Are the LINK P1 LED and LINK P2 LED on?
■For the NZ2FT-MT and NZ2FT-EIP
Are the L/A P1 LED and L/A P2 LED on or flashing?
Is the BF LED on the coupler on in red?
Is the system configuration when the parameters are saved
different from the system configuration to be loaded?
Is the parameter file invalid?
Is the voltage of the coupler power supply (24VDC) within the
specified range?
If the parameter file is still not saved/loaded even after checking all of the above and checking with the LEDs of the I/O module
and Web server, there is a risk of hardware failure in the I/O module.
Acquire the service files, and please consult your local Mitsubishi representative. ( Page 88 Acquisition of the service file)
