TABLES
LOAD CURRENT CALIBRATION
The Model 6DS-SP Planarizer is equipped with current sensors for the polish table
drive motor and both the left and right spindle drive motors. The current sense is
input directly from the servo amplifier unit and received by the control computer
through analog input channels. The analog signal is converted by the ADC to a
digital value. A software subroutine determines and writes the current value to the
monitor’s display screen.
CALIBRATION VARIABLES SET DURING THIS PROCEDURE
63 Table current offset
Nominal value: 0
The "zero" calibration for primary polish table
"Load" value in the status variable area of the
display. If the displayed load value (in amps) is
not zero with the table stopped, add the
negative of the error to the existing value in
variable 63.
