ID 70297

Motion range of axis is bigger than the value range of the absolute measurement system.

Description

For a PROFIDRIVE with absolute encoder, the motion range of the axis, which is defined by the software limit switches (P-AXIS-00177/P-AXIS-00178) is bigger than the value range of the absolute encoder, which is defined by P-AXIS-00092 and P-AXIS-00336.

In this case the mapping of the encoder position to the axis position is not unique.

System error, reboot controller is necessary

Solution

Class

7

Correct P-AXIS-00336. Refer to the drive documentation for the number of revolutions detectable by the absolute encoder. In many cases, this value can also be read out of the drive (P979 Subindex 5).

Otherwise, reduce the axis motion range by resetting the software limit switches P-AXIS-00177/P-AXIS-00178 of the axis.

Parameter

%1:

Logical axis number [-]

Logical axis number of affected axis, see P-AXIS-00016

%2:

Current value [0.1 µm or 0.0001°]

Parameterised motion range of the axis.

%3:

Current value [0.1 µm or 0.0001°]

Maximum motion range of the axis that can be represented by the absolute encoder (P-AXIS-00336 * P-AXIS-00092).

%4:

Current value [-]

Value of P-AXIS-00336.

%5:

Current value[-]

Value of P-AXIS-00092.
