Offsets
For various functions the iBox converts voltages from analog to digital or from digital to analog.
ADC and DAC adjustments allow you to compensate for any conversion offset that might occur.
• Output DAC: Compensates for slight differences that might exist between zero speed com-
manded by the pattern and 0.0 volts appearing between the iBox and the drive input.
• Input ADC: Compensates for slight differences that might exist between the analog input
voltage and the resulting value after the iBox converts that value to a digital equivalent for
internal processing. The Input ADC offset values are determined when the drive setup pro-
cedure is performed. Please refer to "Drive Offsets Calibration" on page
