Input impedance:10kΩ, 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

±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 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.

The motor runs forward when FW terminal is ON, and stops when

FW is OFF.

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.
