17.PMC CONTROL FUNCTION B-63943EN-1/02
- 2014 -
8032
Feedrate for acceleration/deceleration calculation when a feedrate is
specified under PMC axis control
[Input type] Parameter input
[Data type] Word axis
[Unit of data] min
-1
[Valid data range] 0 to 32767
When a feedrate is specified under PMC axis control,
acceleration/deceleration can be set for this parameter or parameter No.
8028. When 0 is set in this parameter, the specification of 1000 min
-1
is assumed. When 0 is set in parameter No. 8028, the
acceleration/deceleration function for feedrate specification is
disabled.
Alarm and message
Servo and overtravel alarms for PMC axis control are detected in the
same way as for CNC controlled axes.
When an alarm is issued, the alarm signal EIALg is set to 1 for
notification to the PMC in addition to normal alarm processing.
(When an overtravel alarm is issued, the negative-direction overtravel
signal EOTNg or the positive-direction overtravel signal EOTPg is
also set to 1.)
The alarm signal EIALg is reset using the reset signal ECLRg.
CAUTION
If an alarm is issued by a PMC axis control command or
in connection with PMC axis control, be sure to set the
reset signal ECLRg to 1 in addition to a reset operation
on the NC.
- Alarms related to contention with the NC
Alarm (PS0130)
In general, if the CNC and PMC attempt to simultaneously control an
axis not subject to superimposition, the alarm (PS0130) is issued.
This alarm is issued in the following cases:
- When cutting feed with an override of 0% is performed along the
axis, or the tool is temporarily stopped along the axis (with the
axis control temporary stop signal ESTP set to 1), this alarm is
issued. (During feed hold or single block stop, a PMC axis
control command is valid, not resulting in an alarm.)
- When a command is issued from the CNC for an axis controlled
by the PMC
- When the axis control superimposed command signal EASIPx is
set to 0 during superimposition
- When a move command is issued from the PMC for an axis on
the polar coordinate interpolation plane in the polar coordinate
interpolation mode (G12.1 command)
