Symbol Name Functions
Main circuit
L1/R, L2/S, L3/T
Main circuit power
inputs
Connects with the three-phase input power lines through a dedicated
reactor.
P(+), N(-)
Converter outputs
Connects with the power input terminals P(+) and N(-) on an inverter.
ok
Grounding
Grounding terminal for the converter’s chassis (or enclosure).
R0, T0
Auxiliary power input for
the control circuit
For the backup of the control circuit power supply, connect the power lines
same as that of the main power input.
Voltage
detection
R1, S1, T1
Synchronous power
input for voltage
detection
Voltage detection terminals for the internal control of the converter. Connect
with the power supply side of the dedicated reactor or filter.
R2, T2
Inputs for control
monitoring
Detection terminal for AC fuse blown.
Input signal
[RUN] Run command
Short-circuiting terminals [RUN] and [CM] runs the converter; opening them
stops the converter.
[RST] Reset alarm command
When the converter stops due to an alarm, removing the alarm factor and
short-circuiting the terminals [RST] and [CM] cancels the protective
function, restarting the converter.
[X1]
General-purpose
transistor input
0: Enable external alarm trip THR
1: Cancel current limiter LMT-CCL
2: 73 answerback 73ANS
3: Switch current limiter I-LIM
4: Option DI OPT-DI
[CM]
Digital input common
Common terminal for digital input signals.
[PLC] PLC signal power
Connects to PLC output signal power supply. (Rated voltage: 24 VDC (22 to
27 VDC)
Output signal
[30A/B/C]
Alarm relay output
(for any alarm)
Outputs a signal when the protective function is activated to stop the
converter.
(Contact: [1C], Terminals [30A] and [30C] are closed: Signal ON) (Contact
rating: 250 VAC, max. 50 mA)
