Analog Output
This function is used to set the analog output channel. The analog signal can be
output into 0-5V voltage or 4-20 mA current. There are four analog output
channels available in PowerFlex 6000 drives – one for actual frequency variant,
one for stator current variant, and the rest are reserved.
The selected variant will undergo a Low-Pass Filter, Amplitude-correction, and
Amplitude-limitation process before the final result is output as a 0-5V and 4-20
mA analog signal. See the following diagram for the process.
Figure 3 - Analog Output Function Diagram
The actual frequency was filtered through the Low-Pass Filter with the filter time
set to one second, amplitude scaling factor to 50%, offset to zero, and the output
channel number is one.
Analog Output #1 Memory Address (P332) = 252
Analog Output #1 Filter Time (P333) = 1000 ms
Analog Output #1 Offset (P334) = 0
Analog Output #1 Scaling Factor (P335) = 50.00%
