Question for the experts. I am trying to box the mouse here and I am blind when it comes to verify/test the LMO-OM (load meter output) wires that come out of the FR-SX spindle drive. Does anyone knows how to diagnose this signal? Is it an analog signal 4-20mA type?
The drive is also showing LEDs 13 and 14 lit meaning "external emergency" alarm, although CON1 has pins 3-4 tied up together from factory. It gets kind of tricky because these LEDs 13 and 14 only turn ON whenever I turn ON the T1 control, but as soon as I turn T1 OFF, the LEDs turn OFF.
I will greatly appreciate any info that will help solve this already too old issue.
