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 A014 to
Frequency Command Terminal
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 voltage, input power, electronic thermal load ratio, and LAD
Digital Monitor (Voltage) frequency.
[Digital pulse output (Pulse voltage DC 0/10V)] Outputs the value of output frequency as
digital pulse (duty 50%)
