3.9 Retraction in the tool direction (JOG retract)
Extended Functions
190 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
Approaching fixed point 2
The control is switched in the JOG mode.
The "Approaching fixed point" function is activated on Fixed Point 2 via the NC/PLC interface
signal:
DB31 DBX13.1 = 1 (Bit 0-2 = 2)
The actuation is confirmed via the NC/PLC interface signal:
DB31 DB75.1 = 1 (Bit 0-2 = 2)
The Plus traverse key in the machine control table is used to traverse continuously to
approach Fixed Point 2.
The machine axis 4 stops at the 90 degree position. This is reported via the NC/PLC
interface signal:
DB31 DBX75.4 = 1 (Bit 3-5 = 2)
3.9 Retraction in the tool direction (JOG retract)
3.9.1 Overview
Function
The function "Retraction in the tool direction in the JOG retract submode", called "JOG
retract" in the following, supports the manual tool retraction in the workpiece coordinate
system (WCS) after a program abort through a power off of the control or a channel reset in
the AUTOMATIC or MDI mode.
In particular, the specific features of the following functions are taken into account:
● Tapping with compensating chuck and speed-controlled spindle with encoder (
G33)
● Tapping without compensating chuck and position-controlled spindle (
G331, G332)
● Machining with tool orientation with swivel cycle CYCLE800 or orientation transformation
Availability
The JOG retract function can be selected only when:
● Tapping using G33/G331/G332
or general:
● A machining with a drilling tool (tool type 200 to 299)
has been interrupted with a channel reset or power off.
