Analog Outputs
Introduction
The G3 has two analog outputs which can be programmed to represent a variety of drive characteristics.
Both outputs terminals, labeled ‘AM’ and ‘FM’, are jumper-selectable to output 0-1 mA DC or 4-20 mA
DC. These outputs are not PWM and are not isolated (do not connect ‘CC’ to ground). On the 0-1 mA
jumper selection, the ‘FM’ or ‘AM’ terminal can also be used as a 7.5 VDC signal.
Connections (connect load to FM and AM terminals when drive is not running)
The jumpers for selection of 0-1 mA or 4-20 mA are located on the terminal strip board just to the left of
the terminal strip. JP3 sets the ‘AM’ terminal’s output range and JP4 sets the ‘FM’ terminal’s output
range.

In general, it is best to calibrate any meter at its maximum deflection to minimize its error as a percentage
of the total signal metered. On the G3, there are two ways of creating a meter maximum deflection
condition for use in calibration:
ON-THE-FLY
ADJUSTMENT AND
100% FIXED OUTPUT
ADJUSTMENT.
Use 100% fixed output for variables that are difficult to hold at maximum condition such as current,
power, input voltage, DC bus voltage, etc.
Use on-the-fly adjustment for variables that can easily be controlled while adjustments to metering are
made such as output voltage and reference frequency.
The table on page 2 shows the functions that can be assigned to ‘FM’/‘AM’.
