Type System parameter
Syntax D_ZONE_MAX=value
Description This sets works in conjunction with D_ZONE_MIN to clamp the DAC output to
zero when the demand movement is complete and the magnitude of the Fol-
lowing Error is less than the D_ZONE_MIN value. The servo loop will be reac-
tivated when either the Following Error rises above the D_ZONE_MAX value,
or a fresh movement is started.
Arguments N/A
Example D_ZONE_MIN=3
D_ZONE_MAX=10
With these 2 parameters set as above, the DAC output will be clamped at
zero when the movement is complete and the Following Error falls below 3.
When a movement is restarted or if the Following Error rises above a value of
10, the servo loop will be reactivated.
See also D_ZONE_MIN.

Type Axis parameter
Syntax DAC_SCALE
Description The parameter has 2 purposes:
1. It is set to value 16 on power up on the built-in axes of the system. This
scales the values applied to the higher resolution DAC so that the gains
required on the axis are similar to those required on the other controllers.
2. DAC_SCALE may be set negative (-16) to reverse the polarity of the
DAC output signal. When the servo is off the magnitude of DAC_SCALE
is not important as the voltage applied is controlled by the DAC parame-
ter. The polarity is still reversed however by DAC_SCALE.
Arguments N/A
Example DAC_SCALE AXIS(3)=-16
See also DAC, S_REF.
