FM Output Terminal Function
Program ⇒ Terminal ⇒ Analog Output Terminals
This parameter is used to set the output function of the FM analog output
terminal. The FM output terminal produces an output current or voltage that is
proportional to the magnitude of the function assigned to this terminal (select
current or voltage at
F681). The available assignments for this output terminal
are listed in Table 6 on pg. 239.
Note: To read voltage at this terminal connect a 100 – 500
Ω
resistor from
the FM (+) terminal to the CC (-) terminal. Using a voltmeter read
the voltage across the 100 – 500
Ω
resistor.
To read current at this terminal connect a 100 – 500
Ω
resistor from
the FM (+) terminal through a series Ammeter to the CC (-) terminal.
The FM analog output has a maximum resolution of 1/1024 and a
maximum load rating of 500 ohms.

FM Output Terminal Adjustment
Program ⇒ Terminal ⇒ Analog Output Terminals
This parameter is used to calibrate the FM analog output.
To calibrate the FM analog output, connect a meter (current or voltage) as
described at
F005.
With the drive running at a known value (e.g., output frequency), adjust this
parameter until the assigned function produces the desired DC level output at
the FM output terminal.
See F005 for more information on this setting.
