AM 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 the AM Terminal Assignment parameter. With the ASD running
at a known frequency, adjust this parameter until the running frequency
produces the desired DC level output at the AM terminal.
Parameter Type — Numerical
Factory Default — 512
Changeable During Run — Yes
Minimum — 1

AM Assignment
This setting determines the output function of the AM analog output terminal.
This 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
Note: To read voltage at this terminal a 100 – 500
Ω
resistor is
required and must be connected from AM (+) to AM (-). The
voltage is read across the 100 – 500
Ω
resistor.
Current may be read by connecting an ammeter from AM (+)
to AM (-).
The AM analog output has a maximum resolution of 1/1024. The AM
Terminal Adjustment parameter 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 providing an output current, or either
0 – 1 or 1 – 7.5 volts when providing an output voltage at this terminal.
