In this display, the output DACs are assigned via drive selection (+/–) and speci-
fication of the axis/spindle name.
The offset input values must make allowance for the output range of the analog
voltage signal. The 611D drive module DACs have an output range of –2.5 V to
2.5 V.
Since the DAC resolution is limited (8 bits), a window can be placed over the
output value by means of the shift factor, i.e. the signal output is decreased
(scaling) when a negative shift factor is input and is increased (scaling) with a
positive shift factor. The input limits for the shift factor vary for SERVO, FDD and
MSD:
The analog output must be set again after Power On Reset.
