The commissioning help is used to determine the reference point offset
in P0162 for the slave drive.
Prerequisites: Set P0179 = 0
1. Carry–out passive referencing as usual (Fig.6-37).
Note
To execute the following points, the master drive must be
precisely positioned at its reference point!
2. Slave drive:
– In the jogging mode, the axis moves to its measured reference
point
Note
Before "jogging", the coupling must be switched–out, otherwise
"jogging" is not possible. Switch–in the coupling again afterwards.
3. Slave drive:
– Set P0179 = 1
––> the distance between the zero mark and approached refer-
ence point is saved as offset in P0162
– P0179 is internally set to 2
4. Save the parameters in the FEPROM
5. Carry–out a power on
This means that for future referencing, the reference point of the slave
drive is "correctly" approached.
The following secondary conditions apply:
S
The slave drive must find its own zero mark during phases 2 and 3.
S
Passive referencing between the master and slave drive is con-
trolled using the following signals:
– Master drive: Output signal "request passive
referencing"
––>
using the output terminal with function number 69
(refer to Chapter 6.4)
––>
using the PROFIBUS status signal QZsw.1
(refer to Chapter 5.6.3)
– Slave drive: Input signal "request passive
referencing"
––>
using an input terminal with function number 69
(refer to Chapter 6.4)
––>
using the PROFIBUS control signal QStw.1
(refer to Chapter 5.6.2)
