3.11 Special features relating to manual and handwheel travel
Extended Functions
212 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
JOG velocity
The velocity used for spindle manual travel can be defined as follows:
● Using general setting data
SD41200 $SN_JOG_SPIND_SET_VELO (speed of spindle in JOG mode), which is valid
for all spindles
or
● Using machine data
MD32020 $_MA_JOG_VELO (JOG axis velocity)
However, the machine data is only effective if
SD41110 $SN_JOG_SET_VELO (axis velocity in JOG) = 0.
The maximum speeds for the active gear stage also apply when spindles are traversed in
JOG mode.

Velocity override
The spindle-override-switch JOG velocity is active for spindles.
JOG acceleration
As a spindle often uses many gear stages in speed-control and position-control modes, the
acceleration associated with the current gear stage is always applied to the spindle in JOG
mode.

PLC interface signals
In the case of spindle manual travel, the PLC interface signals between the NCK and PLC
have the same effect as for machine axes.
Interface signals
DB31, ... DBX60.7 or DBX60.6 (position reached with fine or coarse exact stop)
are only set if the spindle is in position control.
In the case of interface signals that are only spindle-specific, while the spindles are
traversing in JOG the following should be noted:
● The following PLC interface signals to the spindle have no effect:
– DB31, ... DBX17.6 (invert M3/M4)
– DB31, ... DBX18.6/7 (oscillation rotation direction right/left)
– DB31, ... DBX18.5 (oscillation enable)
– DB31, ... DBX16.7 (delete S value)
● The following PLC interface signals from the spindle are not set:
– DB31, ... DBX83.7 (clockwise actual direction of rotation)
– DB31, ... DBX83.5 (spindle in set range)
