Name
Common Terminal for Analog
Common terminal for H, O, O2, OI, AM, and AMI. Do not ground.
Power Source
Power Source for Frequency
Power supply for frequency command input
Setting
Maximum frequency is attained at DC 10V in DC 0-10V range. Set the voltage at
Frequency Command Terminal
A014 to command maximum frequency below DC 10V.
Frequency Command Extra
O2 signal is added to the frequency command of O or OI in DC 0-±10V range. By
Terminal changing configuration, frequency command can be input also at O2 terminal.
Maximum frequency is attained at DC 20mA in DC 4-20mA range.
Frequency Command Terminal
When the intelligent terminal configured as AT is on, OI signal is enabled.
Analog Output Monitor (Voltage)
Selection of one function from:
Output frequency, output current, torque, output voltage, input power, electronic
thermal load ratio, and LAD frequency.
Analog Output Monitor (Current)
[DC0-10V output (PWM output)]
Selection of one function from: Output frequency, output current, torque, output
Digital Monitor (Voltage)
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%)

PLCs, etc.
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.
Intelligent Output Terminals
(Refer to the standard specifications for the functions.)
Both sink and source logic are always applicable between each terminal and CM1.
Common Terminal for
Common terminal for intelligent output terminal 11-15.
Intelligent Output Terminals
The inverter trips when the external thermistor detects abnormal temperature.
Common terminal is CM1.
