AM Terminal Assignment
Program
⇒
Meter Terminal Adjustment Parameters
⇒
AM
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
Table 7 on pg. 61
.
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 (
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 providing an output current, or either 0 – 1
or 1 to 7.5 volts when providing an output voltage at this terminal.

AM Terminal Adjustment
Program
⇒
Meter Terminal Adjustment Parameters
⇒
AM
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.

Changeable During Run — Yes
Minimum — 1
Maximum — 1280

Meter Terminal Adjustment Parameters
⇒
Analog 1
This parameter adjusts the coefficient of the Analog 1 circuit to obtain an
output that corresponds with a known input.
This function is used in the calibration of external signal measuring devices
(DVM, counters, etc.).
