The maximum axis acceleration is defined with the axis-specific MD32300 MAX_AX_ACCEL. The acceleration can also be
set via a preset characteristic curve in "JOG" mode. The possible settings are described in Chapter "Acceleration (B2)
(Page 40)".
A separate PLC interface (DB3200.DBB1000, ff or DB3300.DBB1000, ff ) exists for
(axes in WCS) that
contains the same signals as the axis-specific PLC interface.
When the
is traversed manually, the PLC interface signals between the NCK and PLC have the same effect as for
machine axes. Interface signals "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 spindle is traversing in JOG, the following should be
noted:
● The following PLC interface signals to the spindle have no effect:
– IS "Invert M3/M4" (DB380x.DBX2001.6)
– IS "Set direction of rotation ccw" or "Set direction of rotation cw" (DB380x.DBX2002.7 or .6)
– IS "Oscillation speed" (DB380x.DBX2001.5)
● The following PLC interface signals from the spindle are not set:
– IS "Actual speed cw" (DB390x.DBX2001.7)
– IS "Spindle in setpoint range" (DB390x.DBX2001.5)
Note
A reset causes the manual traverse motion
(axis/spindle) to be terminated with brake ramp.
The following limitations are active for manual travel:
● Software limit switches 1 or 2 (axis must be referenced)
● Hardware limit switches
The control ensures that the traversing movement is aborted as soon as the first valid limitation has been reached. Velocity
control ensures that deceleration is initiated early enough for the axis to stop exactly at the limit position (e.g. software limit
switch). Only when the hardware limit switch is triggered does the axis stop abruptly with "rapid stop".
An alarm is output when the corresponding limit is reached. The control automatically prevents further movement in this
direction. The traversing keys and the handwheel have no effect in this direction.
Note
The software limit switches are only active if the axis has previously been referenced.
Note
The function for retracting an axis that has approached the limit posi
tion depends on the machine manufacturer. For more
details, see the machine manufacturer's documentation.
For further information on working area limits and hardware and software limit switches see Chapter "Axis monitoring (A3)
(Page 24)".
Continuous travel
Selection
When "JOG" mode is selected, the active machine function "continuous" interface signal is set automatically:
● For geometry axes: DB3300.DBX1001.6, DB3300.DBX1005.6, DB3300.DBX1009.6
● For machine axes/spindle: DB390x.DBX0005.6
