Appendix C: Parameter Field Reference
C-73
C.5.15 At Pressure
Default: 50
Range: 0 to 65535
At Pressure specifies the size of a window around the Command Pressure. When the Actual
Pressure gets within this window, the At Pressure bit is set (but not latched) in the Status word.
The window around the Command Pressure and the Actual Pressure must be less than the At
Pressure value. Therefore, an AT PRESSURE value of 0 will prohibit the At Pressure bit in the
Status word from being set.
Example:
If an axis Command Pressure is 2,000 and the AT PRESSURE parameter is 30, the At Pressure
bit will be set when the Actual Pressure is between 1,971 and 2,029. The bit will be cleared
whenever the Actual Pressure is outside the range.
C.5.16 Pressure Window
Default: 250
Range: 0 to 65535
The PRESSURE WINDOW determines how large the difference between the Target Pressure
and Actual Pressure can get before the Following Error bit is set in the Status word.
C.5.17 Auto Stop
Default: 0x1FE0 (Soft Stops enabled, Hard Stops enabled for Transducer Errors)

The Auto Stop parameter controls the action taken on the rising edge of any of the axis' error bits
(the eight (8) most-significant bits in the Status word listed below). The user has control over
which error bits cause which levels of stop, or whether an error will cause a stop at all. The
default setting of all the AutoStops is Hard Stop, as described below.
During startup and tuning, you will typically need to set some AutoStops to Status Only to keep
halts from interfering with the tuning. After completeing the startup procedure, make sure to set
the AutoStops to setting that are safe for the machine operation.
Auto Stops are always active unless the axis is in Open Loop, in which case no Auto Stops will be
triggered even though error bits may be set.
Note: AutoStops will not occur if the axis is in Open Loop!
The eight (8) most-significant bits in the Status word, as listed below, are the error bits, with the
exception of the Home Input status bit for Quadrature axes with Analog (QUAD) or Stepper
(STEP) output:
