AM Terminal Assignment
Program Meter Terminal Adjustment
This setting determines the output function of the AM analog output terminal.
The AM output terminal produces an output current that is proportional to the
magnitude of the function assigned to this terminal.
The available assignments for this output terminal are listed in Table 15 on pg.
193.
Note: Current is read by connecting an ammeter from AM (+) to
AM (-) via a series 100 – 500 resistor.
To read voltage at this terminal a 100 – 500 resistor is
required and it must be connected from AM (+) to AM (-).
The voltage is read across the 100 – 500 resistor.
The AM analog output has a maximum resolution of 1/1024. The AM
Terminal Adjustment (
F671) must be used to calibrate the output signal for a
proper response. SW-1 may be switched to allow for the full-range output to be
either 0 – 1 mA or 4 – 20 mA when measuring an output current, or either 0 – 1
or 1 – 7.5 volts when measuring an output voltage at this terminal.

AM Terminal Adjustment
Program Meter Terminal Adjustment
This function is used to calibrate the AM analog output terminal.
To calibrate the AM analog output, connect a meter (current or voltage) as
described at
F670.
With the drive running at a known frequency, adjust this parameter (F671) until
the running frequency produces the desired DC level output at the AM
terminal.
