Since the L.ERR LED of the FR-E5NC on station
2 is on, the FR-E5NC itself on station 2 is
affected by noise. (L.RUN may go off.)
Securely connect FG of each
inverter and master unit to ground.

Since the L.ERR LEDs of the FR-E5NCs on
station 2 and later are on, the transmission cable
between the inverters of stations 2 and 3 is
affected by noise. (L.RUN may go off.)
Check that the transmission cable
is connected to SLD. Also run it as
far away as possible from the
power lines. (100mm or more)
