Commissioning
Tightening channel
configuration
The flat output drive without safety catch is configured in the open flat output drive channel configuration.
See
Channel configuration of open flat output drives
.
For configuration, activate the option
Open flat key program-controlled
. After sending, the system is
restarted.
Calculation and specification of the
Precise motor screw reduction ratio
:
For positioning accuracy, the total motor screw reduction ratio (I
G
) should be entered with 12 decimal
places.
PLC signals
Referencing and open position of flat output drives without safety catch is realized via the PLC output
signals
GO_Rdy
and
GO_Open
.
See
.
As of version V2.500 of the
Rexroth Tightening System 350,
the PLC input signal
GO_SetRef
is available
for the reference point of the open position. Refer to
Tightening programs
For opening and referencing the flat output drive, new target functions were added to the extended
tightening step in the tightening program. Refer to the "Project planning" documentation of the Rexroth
Tightening System 350:
•
Target function
GO Ref
The open position of the flat output drive of the nutrunner is calibrated in the teach-in process.
•
Target function
GO Open
The nutrunner is rotating in tightening direction until the open position of the flat output drive is
reached. This requires referencing of the flat output drive.
7.8.2.2
Open position referencing
After switching on the system, referencing of the flat output drive in open position is required. Without
referencing, the "open" function
GO Open
of the flat output drive is canceled with error 1245.
Referencing is required:
•
On controller reset / switching on
•
After removal and connection of hand-held nutrunners
•
If the open position cannot be set precisely on opening
The partner controller sets the reference run program via the program selection (see section
).
Application of the new tightening functions
GO_Ref
and
GO_Open
without activation of the
Program-
controlled flat key opening
option leads to error 1213 "Sequence control error".
