3.6.4.2 Parameterization
Note
Monitoring the reference cam
As soon as the parameters for the reference position have been entered and an external
position is linked with the standard process image, the AX5805 expects to see that the
reference cam input is on every time the reference position is crossed.
By default, AX5000 input 0 is configured to be the Reference Cam hardware input. If the
SLP and SCA functions are not to be used and a Reference Cam will not be wired to a
hardware input on the drive, then Input 0 of the AX5000 must remain unconnected or the
AX5805 reference cam hardware input parameter must configured to an unused input of
the AX5000.
Note
Exceeding the maximum range of travel
If the maximum range of travel is exceeded (over travel)the AX5805 activates STO and
removes torque from the motor. There is no direct possibility to re-activate the axes. There
are three possible methods to re-activate the axes:
- Bring the axis mechanically back within the defined range (recommended).
- Force the external position accordingly (not recommended)
- Parameterize the maximum limits of the range of travel accordingly (not
recommended)
