AM Terminal
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
Table 8 on page 142
.
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.

AM 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 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
Maximum — 1280
ASD Number
Program
⇒
Communication Settings
⇒
ASD Number
This parameter plays a role in the setup of the communications network by
assigning an identification (ID) number to each ASD in the communications
network.
The communications network includes other ASDs and Host/Control computers
that monitor the status of the ASD(s), transfers commands, and loads or
modifies the parameter settings of the ASD.
Changes made to this parameter require that the power be cycled (Off then On)
for the changes to take effect.
Note: Valid address numbers for this parameter are 1–247. The
default setting is 0. The default setting must be changed to a
valid setting to use this parameter. Otherwise an Invalid
Address error is returned.
Parameter Type — Numerical
Factory Default — 0
Changeable During Run — Yes
Minimum — 0
Maximum — 255
