9.3 Mode types and mode type change
Supplementary condition for submode TEACH IN
TEACH IN is not permissible for leading or following axes of an active axis grouping, e.g. for:
● Gantry-axis grouping or a gantry axis pair
● Coupled-axis grouping of master and slave axis
JOG in Automatic
JOG in AUTOMATIC mode is permitted if the mode group is in "RESET" state and the axis is
jog-capable. "RESET" state for the mode group means:
● All channels are in the "RESET" state
● All programs are canceled
● DRF is not active in any channel
An axis is JOG-capable if it is not in any of the following states:
● PLC axis as concurrent positioning axis (request of the axis from the PLC)
● Command axis (the axis has been programmed by a synchronized action and the motion
has not been completed yet)
● Rotating spindle (spindle rotating despite RESET)
● An asynchronous reciprocating axis
Note: The "jog-capable" property is independent of the "JOG in AUTOMATIC" function.
Activation
The function "JOG in AUTOMATIC" can be activated with the machine data:
MD10735 $MN_JOG_MODE_MASK
● Before POWER ON, the following machine data must be set:
MD10735 $MN_JOG_MODE_MASK, bit 0 = 1
● The user switches to AUTO (PLC user interface DB11 DBX0.0 = 0→1 edge). "JOG in
AUTOMATIC" is then active if the NCK previously had channel state "RESET" and program
state "Aborted" in all mode group channels. The axis in question must also be "jog-capable".
DRF must be deactivated (if not already deactivated).
● RESET is initiated or the running program is finished with M30/M2 in all mode group
channels that do not have channel state "Reset" and program state "Aborted".
● The relevant axis is automatically made "JOG-capable" (e.g. axis interchanget: PLC → NC).
Note: In most applications, the axes to be traversed are "JOG-capable" and with the switchover
to AUTOMATIC, "JOG in AUTOMATIC" is also active.
Characteristics
● The +/– keys cause a JOG movement, and the mode group is switched internally to JOG.
(i.e. "Internal JOG").
● Moving the handwheels causes a JOG movement, and the mode group is switched
internally to JOG, unless DRF is active.
