RUN/STOP command [RUN] Connect across RUN and CM to boost the voltage, or disconnect to stop.
Alarm reset command [RST]
After removing the cause of the alarm upon alarm stop, connect across
RST and CM to cancel protection and restart operation.

Alarm output
[30A]
[30B]
[30C]
Signal is output upon alarm stop after the protective function of the converter
is activated.
(Contact: 1C. Upon alarm, ON across 30A and 30C)
(Contact capacity: 250 VAC 0.3A cos

common
[CME] Common terminal for transistor output signals. Isolated from terminals CM.
Relay output
(Standard: 1 point) [Y5A]
[Y5C] Signal can be selected similarly to Y1 to Y3 terminals.
The contact capacity is the same as that of the batch alarm output.
General-purpose
analog output
[AO1] Outputs monitor signals of analog DC voltage (0 to ±10 VDC).
Analog output
common
[M] Common terminal for analog output terminals
Charging circuit
control output [73A]
[73C]
Output for controlling external charging circuit
Connect the electromagnetic contactor included in standard accessories.
(Contact capacity: 250 VAC 5A max.)
Terminals [Y5A/C] and [30A/B/C] and [73A/C] use mechanical contacts that cannot stand frequent ON/OFF
switching. Frequent ON / OFF switching signals can be output from the transistor outputs terminals [Y1]
‐
[Y3].
Further, even if an AC power source, in the case of loads, such as direction of the contact current is fixed (such as
load having a half-wave rectifier circuit, for example a timer, the power supply for the motor electromagnetic
brake), contact life is shortened. In such a case, instead of directly connecting the load to the contact output
terminal, the control relay (separately installed) that matches the load requirement is connected to the contact output
terminal, and connected to the load via the relay.
