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.

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
