• Encoder Error only. This bit will go high if the encoder circuitry detects an error, which is defined
as an invalid transition of the A and B lines. This usually occurs due to over-speed or noise
conditions.
• Fault Input only. This bit will go high if the Fault input goes active. The fault input is intended to be
a means for the drive amplifier to let the RMC know that it no longer has control. If the fault input
is not used, it should be made inactive by wiring or by reversing the polarity in the Configuration
Word parameter.
• Encoder Error or Fault Input (default). This bit will go high if either of these conditions occurs. This
is the default behavior for QUAD and STEP axes, but it is ambiguous whether the error was
triggered due to an encoder error or the Fault input.
• Unused. This bit will always be low.
The use of this bit can be set only from RMCWin. Use the following steps:
1. On the Tools menu, click Module Configuration.
2. In the Slots list, click the Quadrature module you want to edit.
3. Click Slot options. The Quadrature with Analog Output Options dialog box will be displayed with a
tab for each axis on that slot.
4. Click the Axis 0 tab.
5. Check the conditions that you want to have set this status bit. You can check one, both, or neither
condition.
6. Click the Axis 1 tab.
7. Check the conditions that you want to have set this status bit. You can check one, both, or neither
condition.
8. Click Update RMC.
9. The Update Module Configuration dialog box will be displayed to indicate the progress. If the
module could not be reset automatically, you may be prompted to reset the module yourself.

The two LEDs above the Drive connector on the RMC’s Quadrature interface card are axis status
LEDs. These LEDs will reflect the operational status, as determined by the Status Word, of their
corresponding axis according to the following table.
