Output/Communication Terminal Labels and Descriptions
Analog
output
AO1
Voltage/Current
Output
Used to send inverter output information to external
devices: output frequency, output current, output
voltage, or a DC voltage.
Operate switch (SW2) to select the signal output type
(voltage or current) at the AO terminal.
Output Signal Specifications:
• Output voltage: 0–10 V
• Maximum output voltage/current: 12 V/10 mA
• Output current: 0–20 mA (Load resistance: Less than
500 Ω)
•
Maximum output current: 24 mA
AO2
Analog voltage
output terminal
Use to send inverter output information, such as output
frequency, output current, output voltage, or DC voltage
to external devices.
• Output voltage: 0–10 V
Maximum output voltage/current: 12V/10 mA
TO Pulse Output
Sends pulse signals to external devices to provide a
single output value from the inverter of either: output
frequency, output current, output voltage, or DC voltage.
Output Signal Specifications:
• Output frequency: 0–32 kHz
• Output voltage: 0–12V
When connecting to a pulse between the S100 inverters,
• Standard I/O(30~75kW) <-> Multiple I/O(0.4~22kW) :
Connect to TO -> TI, CM -> CM
• Standard I/O(30~75kW) <-> Standard I/O(30~75kW) :
Connect to TO -> TI, CM -> CM
• Standard I/O(30~75kW) <-> Standard I/O(0.4~22kW) :

Maximum output current: 150 mA
A1/C1/B1 Fault signal output
Sends out alarm signals when the inverter’s safety
features are activated (AC 250 V <1A, DC 30 V < 1A).
• Fault condition: A1 and C1 contacts are connected (B1
and C1 open connection)
Normal operation: B1 and C1 contacts are connected
