Diagnostic Messages
DOK-INDRV*-MP*-02VRS**-FK01-EN-P
Determining threshold values for "In Position" message:
• S-0-0057, Position window
• S-0-0124, Standstill window
See also Parameter Description "S-0-0013, Class 3 diagnostics"
If the position data are scaled in modulo format, it is possible to specify
limiting conditions that improve the reproduction of the positioning
process:
• S-0-0417, Positioning velocity threshold in modulo mode
• S-0-0418, Target position window in modulo mode
The target position of the spindle is preset via
• S-0-0153, Spindle angle position (absolute positioning)
- or -
• S-0-0180, Spindle relative offset (relative positioning).
Spindle positioning is started by starting the command
• S-0-0152, C0900 Position spindle command
The target position effective for the positioning process is displayed in
• S-0-0430, Effective target position.
When the target position has been reached, this is displayed in
• S-0-0336, Message In position
- and -
• S-0-0013, Class 3 diagnostics.
The respective message bit changes from "0" to "1" when the conditions
for the message have been fulfilled. The execution of the "position
spindle" command is thereby acknowledged as having been "completed
without error".
The execution of spindle positioning required drive enable (AF).
Diagnostic message in the case of error:
• C0902 Spindle positioning requires drive enable
If an absolute encoder is used as control encoder, the position data
reference of the encoder must have been established before the first-time
start of spindle positioning. Diagnostic message in the case of error:
• C0903 Error during initialization
If a relative encoder is used as control encoder and a home switch is to
be evaluated, the position data reference is established with the first-time
spindle positioning (unless already done). If the drive does not recognize
the home switch signal, the following diagnostic message is generated:
• C0903 Error during initialization
If a relative encoder is used as control encoder, the position data
reference is established with the first-time spindle positioning (unless
already done). If the drive does not recognize any reference mark signal,
the following diagnostic message is generated:
• C0906 Error during search for zero pulse
