When the intelligent terminal configured as AT is on, OI signal is enabled.
Selection of one function from:
Output frequency, output current, torque, output voltage, input
power, electronic thermal load ratio, and LAD frequency.
[DC0-10V output (PWM output)] Selection of one function from:
Output frequency, output current, torque, output voltage, input
power, electronic thermal load ratio, and LAD frequency.
[Digital pulse output (Pulse voltage DC 0/10V)] Outputs the value
of output frequency as digital pulse (duty 50%)
Internal power supply for input terminals. In the case of source
type logic, common terminal for contact input terminals.
Common Terminal for Interface
Common terminal for P24, TH, and FM. In the case of sink type log-
ic, common terminal for contact input terminals. Do not ground.
Select sink or source logic with the short-circuit bar on the control
terminals.
Sink logic: Short P24 to PLC / Source logic: Short CM1 to PLC.
When applying external power source, remove the short-circuit bar
and connect PLC terminal to the external device.
Assign 5 functions to open collector outputs.
When the alarm code is selected at C062, terminal 11

14 are reserved for error codes of inverter trip.
(Refer to the standard specifications for the functions.)
Both sink and source logic are always applicable between each
terminal and CM1.
The inverter trips when the external thermistor detects abnormal
temperature. Common terminal is CM1.
[Recommended thermistor characteristics]
Allowable rated power: 100mW or over.
Impedance in the case of abnormal temperature: 3kΩ
Note: Thermal protection level can be set between 0 and 9999Ω.
