Drive Offsets Calibration
The iBox processes 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 converted
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.
This section describes both automated and manual procedures that can be used to calibrate
drive analog circuitry. MCE recommends using the automated procedure first and then verify-
ing the most critical offsets using the manual procedure.
Automated Drive Setup Procedure
Before adjusting the drive, verify that:
• the CONTROLLER STOP switch is in the RUN position
• the iBox Safety OK LED is ON
• the iBox Door Locked LED is ON
• the iBox Fault LED is OFF
