How do I scale analog inputs?
Analog input and outputs can be scaled to meet an applications needs. This allows the VFD to run at the correct speed based on a voltage or current signal input. Similarly, the analog outputs may be scaled to properly display on a meter.
Below is an example and references for scaling the I2 current input on an S100 VFD. Please refer to the specific VFD series manual for other VFDs.
Example:
An application requires 5.5mA to equate to 30HZ and 20mA equate to 60Hz.
Associated parameters
Required Settings:
- IN53=5.5mA
- IN54=50%
- IN55=20mA
- IN56=100%
Voltage can be changed as well within the same parameter. This can be changed using In. 12 and In.15.
