DISPLAY
OPTION
EFFECT
Visual Display
Channel
Defines which channel is displayed on the Analog and Binary Displays.
Constant
Read
Constantly updates all channels.
Card Speed
Algorithm
Selects either One-Speed or Two-Speed input mode.
Inhibit
Inhibits the output display.
Turns Count *
Displays the turns count status for each channel. Reset will reset each
individual channel’s turn count to zero. (*See NOTE)
Direction
Displays the direction of rotation. Up is counterclockwise (angle
increasing), Down is clockwise (angle decreasing).
BITE
Reads the status of the BIT output of the R/D converter. The reasons a
fault may be indicated in a R/D converter are as follows:
1. The synchro or resolver signals have fallen below the specified
voltage amplitude or there are no analog input signals connected to
the R/D converter.
Note:
Both SIN and COS signals of the R/D converter must fall below
0.5 Vrms, or else the BIT may only indicate a fault at certain
angles.
2. The synchro or resolver is moving at a rate greater than the R/D
converter can accommodate. The dynamic capability of the R/D
converter is determined by the bandwidth selection and the
resolution (refer to hardware setup).
3. If the error exceeds approximately 100 LSB’s. This condition will
occur during a large step and reset after the converter settles out.
* Note:
The Encoder must be enabled for the turns counter and the direction
to work properly for both the DOS console and the Windows GUI.
Encoder (A quad B) resolution must be of equal or lesser value than
the resolution set on the card. For example, if the resolution set on
the card is 14 bits, the A quad B resolution must be set to 14 bits or
less (not 16 bits).
