Drive Offsets Calibration

This section describes both the automated and manual procedures which can be used to cali-
brate the drive analog circuitry. MCE recommends using the automated procedure.
iBox handles processing of drive control voltages digitally. The digital signal is converted to its
analog equivalent for output to the drive (DAC). Analog input control voltages are likewise con-
verted from analog to digital for use by the iBox (ADC). Both of these conversions should be
checked and any conversion offset corrected using the Output DAC and Input ADC parameters
on the Configuration > Drive > Calibration tab.

Automated Drive Setup Procedure

Before adjusting the drive, verify that:
• the iBox Safety OK LED is ON
• the iBox Door Locked LED is ON
• the iBox Fault LED is OFF
1. Display the Drive setup layout (View > Layouts > Drive)
2. Follow the on-screen instructions, "To perform the drive offsets calibration, ..." (cali-
brates Input ADC and Output DAC offset).
