In default setting, an alarm is activated when inverter output is turned off by a protective
function.
Common terminal for H, O, O2, OI, AM, and AMI. Do not ground.

Input impedance: 10k½, Allowable
input voltage range: DC -0.3-+12V
DC 10V, 20mA max.
Input impedance:10k½, Allowable
input voltage range: DC 0-±12V
Maximum frequency is attained at DC 10V in DC 0-10V range. Set the voltage at A014 to
command maximum frequency below DC 10V.
O2 signal is added to the frequency command of O or OI in DC 0-±10V range. By
changing configuration, frequency command can be input also at O2 terminal.
Maximum frequency is attained at DC 20mA in DC 4-20mA range.
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 fre-
quency.
[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 termi-
nal for contact input terminals.
Common Terminal for Interface
Common terminal for P24, TH, and FM. In the case of sink type logic, 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 ter-
minal to the external device.
Assign 5 functions to open collector outputs.
When the alarm code is selected at C062, terminal 11-13 or 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: 3k½
Note: Thermal protection level can be set between 0 and 9999½.

The motor runs forward when FW terminal is ON,
and stops when FW is OFF.
[Input ON condition]
Voltage between each terminal
and PLC: DC 18V min.
