Analog output, transistor output, and relay output terminals
Symbol Name
[FM1] Analog monitor
[FM2]
[11] Analog common
These terminals output monitor signals of analog DC voltage (0
to +10 V) or analog DC current (+4 to +20 mA DC or 0 to +20
mA DC).
The output form (VO/IO) for [FM1] or [FM2] can be switched
by the slide switch (SW4/SW6) on the control PCB and the
function code F29/F32, as listed below.

The signal function can be selected from the following with
function code F31/F35.
• Output frequency • Output current
• Output torque • Load factor
• PID feedback amount • DC link bus voltage
• Universal AO • Motor output
• Calibration • PID command
• PID deviation • Reference frequency
• Customizable logic output signal
• Inverter heat sink temperature
• Reference frequency, etc.
For details, refer to Chapter 6 "FUNCTION CODES."
- Input impedance of external device: Min. 5kΩ (at 0 to 10 VDC
output)
(While the terminal is outputting 0 to 10 VDC, it is capable of
driving up to two analog voltmeters with 10 kΩ impedance.)
- Input impedance of external device: Max. 500Ω (at 4 to 20 mA
DC output)
- Adjustable range of the gain: 0 to 300%
Two common terminals for analog input and output signals.
These terminals are electrically isolated from terminals [CM]s
and [CMY].
