Function
Main circuit
R, S, T
Main power supply input
Connect to a three-phase power supply via a dedicated reactor.
P, N
Converter output
Connect to inverter power supply input terminals P and N.
R0, T0
Control power auxiliary input
These are backup terminals for the control power. (30 kW or higher)
G
Grounding terminal
This is a terminal for grounding.
Ri, Si, Ti
Synchronous power supply input
for voltage detection
This is a voltage detection terminal used for control inside the converter,
and is connected to the dedicated filter power supply side.
73A, C
Charging circuit control output
This is the control output for the external charging circuit.
Contact capacity: 250 VAC, 5 A
Control input terminals
RUN
RUN / STOP commands
Runs when ON across RUN and CM, and stops when OFF.
RST
Alarm reset command
By eliminating the cause of the alarm when an alarm stoppage occurs, and
turning ON between RST and CM, the protective function that was
activated is canceled, and operation resumes.
X1, X2
Digital input
(SINK / SOURCE)
Signals selected from the following functions can be input.
0: External alarm [THR], 1: Current limiting cancel [LMT-CCL],
2: 73 answerback [73ANS], 3: Current limiting switch [I-LIM],
14: Universal DI [U-DI], 15: AC fuse blown [ACF]
PLC
PLC signal power supply
Connects the power supply for PLC output signals. The terminal can also
be used as the power supply for loads connected to transistor outputs.
Rated voltage: +24 V (22 to 27 VDC), max. output current: 100 mA
CM
Digital input common
This is a common terminal for digital input signals.
Control output signals
30 A
Total alarm output
(non-voltage contact signal (1C)
output)
A signal is output when the protective function activates and an alarm
stoppage occurs.
Contact capacity: 250 VAC, 0.3 A, cosφ = 0.3
30B
30C
Y1, Y2, Y3
Transistor output
Signals selected from the following functions can be output.
0: Running [RUN], 1: Ready for operation [RDY], 2: Power supply current
limiting [IL], 3: Lifetime early warning [LIFE], 4: Cooling fin overheating
early warning [PRE-OH], 5: Overload early warning [PRE-OL], 6: Power
running [DRV], 7: Regenerating [REG],
8: Current limiting warning [CUR], 9: Restart after momentary power failure
[U-RES], 10: Source frequency synchronization [SY-HZ], 11: Alarm
information [AL1], 12: Alarm information [AL2], 13: Alarm information [AL4],
14: DC fan lock [DCFL], 25: Universal DO [U-DO],
27: Cooling fan running [FAN], 32: Alarm output (for any alarm) [ALM], 33:
Y-terminal test output ON [Y-ON], 34: Y-terminal test output OFF [Y-OFF]
CMY
Transistor output common
This is a common terminal for transistor output signals.
Y5A
Relay output
Signals can be selected in the same way as terminals Y1 to Y3.
Contact capacity: 250 VAC, 0.3 A, cosφ = 0.3
Y5C
FM1, FM2
Analog output
The following monitor signals are output by selecting from analog DC
voltage 0 to 10 V, DC current 4 to 20 mA, or in pulse 25 to 32000 p/s.
(FM2 can output DC voltage only).
0: Power supply side power [PWR] 200%/+10 V,
1: Power supply side current RMS value [I-AC] 200%/+10 V,
2: Power supply side voltage RMS [V-AC] 250 (500) V/10 V,
3: Intermediate DC voltage [V-DC] 500 (1000) V/10 V,
4: Power supply frequency [FREQ] 100 Hz/10 V,
5: +10 V output test [P10]
M
Analog output common
This is a common terminal for analog output signals.
Communication
RJ-45
connector
For keypad connection
RJ-45 connector
This is used to connect the keypad. The keypad power is supplied from the
converter via an extension cable for remote operation.
RS-485 communication port
This is used to connect a computer or programmable controller, etc. by RS-
485 communication.
