Suppression Of The Gear Stage Change For Dryrun, Program Test And Serupro - Siemens SINUMERIK 840D Function Manual

When changing from axis mode to spindle mode, the gear stage loaded with M70 remains
activated. The gear stage which is activated in spindle mode prior to M70 is not automatically
loaded again. The servo parameter set is changed from parameter set 1 (index 0) to parameter
sets 2 ... 6 (index 1 ... 5) to suit the gear stage (with
MD35590 $MA_PARAMSET_CHANGE_ENABLE < 2).
Example
Gear stage 4 should be loaded in the case of spindle transition to axis mode.
Configuration: MD35014 $MA_GEAR_STEP_USED_IN_AXISMODE[<spindle name>] = 4
Program code
N05 M3 S1000
N10 G1 X100 F1000
N15 M70
N20 POS[C]=77
N25 ...
Note
MD35014 can be changed by the "Activate machine data" function. Thus, the gear stage being
loaded can still be changed in the part program before transition to axis mode, if necessary.

Suppression of the gear stage change for DryRun, program test and SERUPRO

Function
For test feed rate (DryRun), program test and SERUPRO, normally, a gear stage change is not
required. This is the reason that it can be suppressed for these functions. The corresponding
configuration is realized with bits 0 ... 2 in machine data:
MD35035 $MA_SPIND_FUNCTION_MASK
Dry run feedrate (DryRun)
Bit 0 = 0
Bit 0 = 1
Program test and SERUPRO
Bit 1 = 0
Axes and spindles

Comment
; Gear stage 4 is loaded.
When the DryRun function is active - for part program blocks - gear stages are changed
with M40, M41 to M45, or programming via FC18 and synchronized actions.
When the DryRun function is active - for part program blocks - a gear stage change is
suppressed with M40, M41 to M45, programming via FC18 and synchronized actions.
For active program test / SERUPRO function - for part program blocks - gear stages are
selected with M40, M41 to M45, programming via FC18 and synchronized actions.
