288*
Default value
2 000
The specified value applies to travel in JOG mode with the feedrate override switch set to
100%.
The value in NC MD 288* must not exceed the maximum feedrate (NC MD 280*).
292*
Default value
5 000
The specified value applies to travel in JOG mode with the rapid traverse override key
actuated and the rapid traverse override switch set to 100 %.
The value defined in NC MD 292* must not exceed the maximum speed (NC MD 280*).
The value in NC MD 292* is not used for programmed rapid traverse G00, which is defined by
the maximum speed entered in NC MD 280*.
Recommended value
The selected value should be slightly lower than rapid traverse rate G00 to make allowance for
the operator's response time.
296*
Default value
10 000
If the Direction key leading to the reference point is depressed in "Reference point approach"
mode, the axis accelerates to the reference point approach speed. (Exception: The axis is
already at the deceleration cam or automatic reference point approach has been selected; also
refer to NC MD 244*).
The direction of reference point approach is specified in NC MD 564*.
The value entered in NC MD 296* must not exceed the maximum speed (NC MD 280*).
Also refer to Section entitled "Axis (Analog) and Spindle Installation" for details on reference
point approach.
300*
Default value
500
The specified speed takes effect in incremental feed mode only (INC1 ... 10 000), and must
not exceed the maximum speed (NC MD 280*).
When traversing with the handwheel in modes INC1 ... 10 000 or with the DRF function, the
speed is determined exclusively by the handwheel.
