Parameter Errors 7.4

Support and Troubleshooting 7-9

7.4.8 Auto-Repeat Should Not be Used on Linear Axes with a

Curve that Does Not Match Endpoints

All of the following was true:

• An Auto-Repeat curve was downloaded to an axis with an absolute transducer type such as

MDT, SSI, or Analog, which cannot be offset.

• The curve's first and last points were at different positions.

• The curve was followed beyond its last point, thus triggering an Auto-Repeat.

If any of the above was not true, then an error would not have been generated. That is, Auto-

Repeat curves are allowed on non-offsettable axes, provided their endpoints match. However,

because this situation did occur, the curve still Auto-Repeated, but did not offset the position back

to the first position in the curve.

7.4.9 Axis must be initialized to use this command

Many commands require that the axis to which they are issued be initialized. An axis is initialized

if the Axis Initialized bit is set in its Status Word, which happens when the axis receives a Set

Parameters (P) command. Ensure that you have issued this command the axis that got this error.

The only way the Axis Initialized bit will clear is if the module is reset, as will happen when power

to the module is cycled.

7.4.10 Axis must be stopped for this command

The 0x60 (`) command "Set Absolute Rotary Encoders to Same Turn" requires that the axis be

stopped or in open loop. This command was ignored because the axis was not in either of these

states.

This command is available in the 'B' code only.

7.4.11 Both sync bits cannot be set in the "Mode" word

There are two Sync bits in the MODE word. Only one or neither can be set at a time. This

parameter error is generated if both are set.

7.4.12 Cannot clear a segment while interpolating

This indicates that a Clear Spline Segments command was issued while a Follow Spline Segment

command was in progress. Because splines are cleared from the oldest to the newest, and the

currently followed spline is the newest, it is not possible to clear any segments while the current

spline is being followed.
