Assignment |
|
| Factory Default — Output Current | ||
|
|
|
| ||
This setting determines the output function of the AM analog output terminal. | Changeable During Run — Yes | ||||
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 – 500Ω resistor is |
| ||||
required and must be connected from AM (+) to AM |
| ||||
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 parameter must be used to calibrate the output signal for |
| ||||
a proper response. |
| ||||
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. |

This function is used to calibrate the AM analog output terminal. | Changeable During Run — Yes | ||||
|
|
|
| ||
To calibrate the AM analog output, connect a meter (current or voltage) as | Minimum — 1 | ||||
described at the AM Terminal Assignment parameter. With the ASD running | |||||
| |||||
at a known frequency, adjust this parameter until the running frequency | Maximum — 1280 | ||||
produces the desired DC level output at the AM terminal. | |||||

Changes made to this parameter require that the power be cycled (Off then On) |
| ||||
for the changes to take effect. |
