Analog Output [FM1] and [FM2] (Mode selection, Voltage adjustment, Function)
These function codes allow terminals [FM1] and [FM2] to output monitored data such as the output frequency and the
output current in an analog DC voltage or current. The magnitude of such analog voltage or current is adjustable.
Mode selection (F29 and F32)
F29 and F32 specify the property of the output to terminals [FM1] and [FM2], respectively. You need to set the slide
switches on the control printed circuit board (control PCB). Refer to Chapter 2 "Mounting and Wiring of the Inverter."

The output current is not isolated from analog input, and does not have an isolated power supply. Therefore, if an
electrical potential relationship between the inverter and peripheral equipment has been established, e.g., by
connecting an analog, cascade connection of a current output device is not available.
Keep the connection wire length as short as possible.
Voltage adjustment (F30 and F34)
F30 allows you to adjust the output voltage within the range of 0 to 300%.
Function (F31 and F35)
F31 and F35 specify what is output to analog output terminals [FM1] and [FM2], respectively.
