Program execution with dry run feedrate

Function
During "Program execution with dry run feedrate" the traversing speeds which have been
programmed together with G01, G02, G03, G33, G34 and G35, are replaced by a
parameterized feedrate value:
SD42100 $SC_DRY_RUN_FEED (dry run feedrate)
The dry run feedrate also replaces the programmed revolutional feedrate in program blocks
with G95.
The exact way of working of the parameterized dry run feedrate (SD42100) depends on the
setting of another setting data:
SD42101 $SC_DRY_RUN_FEED_MODE (mode for test run speed)
Value
0
1
2
10
11
12
A dry run feedrate can be selected in the automatic modes and activated on interruption of an
automatic mode or end of a block.
For further information on influencing the feedrate, see Section "V1: Feedrates (Page 1307)".

Meaning
Dry run feedrate is the maximum of the programmed feedrate and setting data SD42100.
(Default setting!)
⇒ SD42100 becomes effective only when the stored value is greater than the programmed
feedrate.
Dry run feedrate is the minimum of the programmed feedrate and SD42100.
⇒ SD42100 becomes effective only when the stored value is less than the programmed fee‐
drate.
The value in SD42100 acts as the dry run feedrate, regardless of the programmed feedrate.
As in the case of "0", except thread cutting (G33, G34, G35) and thread boring (G331, G332,
G63). These functions are executed as programmed.
As in the case of "1", except thread cutting (G33, G34, G35) and thread boring (G331, G332,
G63). These functions are executed as programmed.
As in the case of "2", except thread cutting (G33, G34, G35) and thread boring (G331, G332,
G63). These functions are executed as programmed.
