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 5 on pg. 50.
Note: To read voltage at this terminal a 100 – 500Ω resistor is required and
must be connected from AM (+) to AM (-). The voltage is read across the
100 – 500Ω 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.
Direct Access Number — F670
Parameter Type — Selection List
Factory Default — Output Current
Changeable During Run — Ye s
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.

Parameter Type — Numerical
Factory Default — 512
Changeable During Run — Ye s
Minimum — 1
Maximum — 1280
Analog 1 Terminal Setting
Program ⇒ Meter Terminal Adjustment Parameters ⇒ Analog 1
This parameter sets the Analog 1 multifunction programmable terminal to 1 of
31 possible functions and is available on the ASD Multicom option board only.
Possible assignments for this output terminal are listed in Table 5 on pg. 50.
Direct Access Number — F672

Analog 1 Terminal Adjustment
Program ⇒ 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.).
