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.

Direct Access Number — F670

Parameter Type — Selection List

Factory Default — Output Current

Changeable During Run — Yes

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-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 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.
