Description
Turns ON at alarm occurrence and reset (RES) signal input.
Connect this terminal to the terminal MRS or a terminal where
the X10 signal is assigned to in the inverter.
Turning ON RDY signal stops the inverter.
RYD signal OFF: Inverter can run
RYD signal ON: Inverter cannot run
Signal is output during harmonic suppression.
Output item: OL signal (overload alarm) (initial setting)
Turns ON at an occurrence of overcurrent (150% overload or
more).
Output item: PHS signal (power phase detection) (initial
setting)
Turns ON when power phase detection is locked.
Turns ON at a converter reset (RES-ON).
Connect this terminal to the inverter terminal of which RES
signal is assigned to.
Reset the connected inverter by turning ON the RSO.
Common terminal for the terminals RDY, CVO, OL, Y1, Y2
Connect it to the inverter terminal SD (sink logic).
Select one monitor item from multiple monitor items such as
input current and bus voltage. Not output during a converter
reset.
The output signal is proportional to the magnitude of the
corresponding monitoring item.
Monitor item can be switched by ON/OFF of terminals X1 and
X2.
Common terminal for analog signal output
1 changeover contact output indicates that the converter's
protective function is activated and the output is stopped.
Fault: No conduction across B and C (Conduction across A
and C),
Normal: Conduction across B and C (No conduction across A
and C)
Controls the MC for the limit resistor.
Description
Output item: Y5 signal (output voltage match) (initial setting)
Turns ON when the detected bus voltage equals to the
commanded bus voltage.
