13. d20: (not used) – Parameter value d20 programs a Multi-function Input
Terminal: M1 (Pr.38), M2 (Pr.39), M3 (Pr.40), M4 (Pr.41) or M5 (Pr.42) to provide no
function.
Application Note:
The purpose of this function is to provide isolation for unused Multi-function Input
Terminals. Any unused terminals should be programmed to d20 to insure they have no
effect on drive operation.
Pr.43 Analog Output to Drive External Meter
Factory Setting d00
Units None
Settings d00 Analog frequency meter (0 to Maximum Frequency, Pr.03)
d01 Analog current meter (0 to 250% of the rated drive output current)
This parameter selects the AC drive output frequency or output current that will be
proportional to the analog meter output signal voltage (DC: 0v - 10v).
Pr.44 Analog Output Gain (can be programmed while the drive is running)
Factory Setting d100%
Units 1%
Parameter value d01 - d200%
This function regulates voltage level of the AC motor drives analog signal output (either
frequency or current output) at the AFM output terminal, which is then fed to a frequency
or current indication meter.
The analog voltage output is proportional to the AC
drive output frequency. The AC drive's Maximum
Output Frequency (Pr.03) is equivalent to 10 v DC. If
required, adjust the output level using Pr.44, Analog
Output Gain.
The analog voltage output is proportional to the AC
drive output current. 10 v DC of analog is equivalent to
2.5 times the AC drive's Rated Output Current. If
required, adjust the output level using Pr.44, Analog
Output Gain.
