Use the AMP parameters described in this section only when the control is
operating in 7300 mode. This feature allows existing part programs from
Allen-Bradley 7320 and 7360 tapes to be read, and executed using the
control. Refer to Appendix D of your programming and operation manual
for details on 7300 mode.
Important: To use the 7300 tape compatibility feature, the system installer
must have developed PAL to enable this feature. Refer to the system
installer’s documentation or your reference manual for details on how the
7300 series CNC tape format feature is activated.
This feature is not available on the 9/230 control and Grinder
configurations.
Function
This parameter is used by mill controls when operating in 7300 mode and
calling one of these cycles:
G-code Cycle
G82 Drilling cycle (dwell, rapid out)
G88 Boring cycle (spindle stop, manual out)
G89 Boring cycle (with dwell, feed out)
This parameter is not available for lathe or grinder controls.
Use this parameter to determine the time the drilling axis remains at the
bottom of the hole (dwells) before retracting to the R-plane. Enter a dwell
duration in seconds.
For details on the operation of a dwell in a fixed cycle, refer to the P word
discussion in your mill programming and operation manual. The control
takes the dwell time you assign here and uses it as the value of P in the
fixed cycle format.
Important: When performing a dwell in a fixed cycle while in 7300 mode,
only a dwell in units of seconds is available. A dwell cannot be performed
in units of spindle revolutions.
