15. PMC CONTROL FUNCTION
757
8028
Linear acceleration/deceleration time constant for jog feed specified
by the speed command for each PMC–controlled axis
[Data type] Word axis type
[Unit of data] msec/1000 rpm
[Valid data range] 0 to 32767
Specify, for each PMC–controlled axis, the time needed to increase or
decrease the speed of the servo motor by 1000 rpm, that is, the time
constant of linear acceleration/deceleration for jog feed according to the
speed specified for that axis.
NOTE
If 0 is specified, the system does not control the
acceleration/deceleration.
A servo alarm or overtravel alarm for a PMC–controlled axis is detected
in the same way as an alarm for a CNC–controlled axis.
If an alarm occurs, the alarm is handled by applying the normal procedure,
alarm signal EIALg being set to “1” to inform the PMC of the alarm.
(If an overtravel alarm occurs, either negative overtravel signal EOTNg
or positive overtravel signal EOTPg is also set to “1”.)
If the PMC issues a command for a CNC–controlled axis, a P/S alarm No.
130 occurs.
Commands issued by the PMC are effective if the axis is in feed hold or
single block stop mode. The command results in the issue of an alarm if
cutting feed is executed with an override of 0%, or if the interlock is
enabled.
If the CNC issues a command for a PMC–controlled axis, a P/S alarm No.
130 occurs.
If the PMC issues a movement command for an axis in the plane of polar
coordinate interpolation in polar coordinate interpolation mode (G12.1),
a P/S alarm No. 130 occurs.
