Parameter Type — Selection List

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 – 500resistor is

 

required and must be connected from AM (+) to AM (-). The

 

voltage is read across the 100 – 500resistor.

 

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-1may 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.

Factory Default — 512

 

 

 

 

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

Changes made to this parameter require that the power be cycled (Off then On)

 

for the changes to take effect.

 

 

Note: Validaddress 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
