6.12.1 Input Descriptions
Each of the single bit input functions has a Configuration setting of Contact Type. The Contact Type can be
Normally Open (N.O.) or Normally Closed (N.C.). If an input’s contact type is normally open, the input is asserted
when 24V DC is applied to the 24V DC connector input pin, or when the fieldbus bit transitions from low to high.
If an input’s contact type is normally closed, the input is asserted when 24V DC is removed from the 24V DC
connector input pin, or when the fieldbus bit transitions from high to low.
The Input functions assert on the transition only.
Job or Task selection can come from multiple inputs at once, including the MFB. There is no priority, each one
is equal. The Alpha controller switches its active Job or Task with each input change. The last one to change
becomes the active Job or Task.
Spindle – Indicates to which spindle in the multi-spindle system this function applies.
Inputs
Description
DISABLE JOB
When asserted on any input bus, the controller disables the tool while this specific job is selected. This acts like a
STOP to stop the tool during use. Use the JOB parameter under Configuration to select the job to be disabled while
this input is asserted.
When removed the tool will be allowed to run while this specific job is selected.
Size: 1 bit
Configuration:
Contact Type: Normally Open (N.O.), Normally Closed (N.C.)
Job: Type the job number to select when this input is asserted.
Spindle: Type the spindle number in which the Job is to be disabled.
DISABLE TASK
When asserted on any input bus, the tool is disabled while this specific task is selected. This acts like a STOP to stop
the tool during use. Use the Task parameter under Configuration to select the disabled task.
When removed, the tool will be allowed to run while this specific task is selected.
Size: 1 bit
Configuration:
Contact Type: Normally Open (N.O.), Normally Closed (N.C.)
Task: Type the task number to disable when this input is asserted.
Spindle: Type the spindle number in which the Task is to be disabled.
