Spindle job
In order to start a job, the channel handling the spindle must be in the acceptance status. A
spindle job is always started on the LowHigh edge of a DBB30 signal.
Generally, the DBB30 start signals do not have any meaning in the static status and do not
prevent the spindle being programmed by FC18, synchronized actions, the part program or
JOG traversing movements (e.g., when the STOP signal is statically at "1").
Conditions for the acceptance status
Outside a running part program, spindles can be started and stopped using the special VDI
interface signals NCK → PLC.
For this, the channel status in "Interrupted" mode:
DB21, ... DBX35.6 = 1
or "Reset":
DB21, ... DBX35.7=1
and the program status must be in "Interrupted" mode:
DB21, ... DBX35.6 = 1
or "Aborted":
DB21, ... DBX35.4 = 1.
These states will occur on RESET and in JOG mode.
At the start time, the spindle concerned must meet the following requirements:
• It must be in the status "Channel axis" or "Neutral axis" and must not be moved by means
of the JOG keys.
• When the spindle is specified, no positioning movement may be carried out by FC18 or
synchronized actions.
Spindle job outside the acceptance range
Low-High edges outside the acceptance range will be ignored. No alarm message is output
by the NCK. It can be assumed that the acceptance range will be indicated to the operator
by the PLC program.
Spindle jobs outside the acceptance range can also be carried out using FC18 or ASUB.
