Explanation of the parameters
Parameters
•
Type 3: CW limit switch
– First search direction is CW.
– Reference position = First zero pulse or falling edge to the left of the right limit
switch.
– Machine zero = reference po reference offset
– Reference travel should take place to zero pulse.
•
Type 4: CCW limit switch
– First search direction is CCW.
– Reference position = First zero pulse or falling edge to the right of the left limit
switch.
– Machine zero = reference po reference offset
– Reference travel should take place to zero pulse.
•
Type 5: No reference travel
– Reference position = current position
– Machine zero = reference offset
•
Type 6: Reference cam flush with CW limit switch
– First search direction is CW.
– Reference position = First zero pulse or falling edge to the left of the reference
cam
– Machine zero = reference po reference offset
– Note: Reference cam and limit switches must be flush!
•
Type 7: Reference cam flush with CCW limit switch
– First search direction is CCW.
– Reference position = First zero pulse or falling edge to the right of the reference
cam
– Machine zero = reference po reference offset
– Note: Reference cam and limit switches must be flush!
P904 Reference
travel to zero pulse
Setting range: YES / NO
•
YES: Reference travel takes place to the zero pulse of the selected IPOS
plus®
en-
coder.
•
NO: Reference travel takes place to the falling edge of the reference cam.
P905 Hiperface
offset X15
Setting range: –(2

– 1) ... 0 ... 2

– 1
This parameter is used to specify the zero point of the motor encoder display.
Use this parameter to define the machine zero without reference travel. It adds or sub-
tracts the offset from the encoder value.
•
P905 Hiperface offset X15 has an effect on the actual position of the motor encoder
H511.
H511 = Encoder value – P905
The actual position is determined directly after the values have been entered. A HIPER-
FACE
®
multi-turn encoder must be referenced once, a HIPERFACE
®
single-turn encod-
er must always be referenced.
Note:
When reference travel of a drive system takes place with a HIPERFACE
®
encoder, the
reference travel will recalculate and overwrite the Hiperface offset (P905 or P947) de-
pending on the set actual position source .
The following applies:
•
P905 = Encoder value – P900
P6..
P60.
P600
