| Encoder Inputs
|
| |
| The A, B and Z
inputs may be configured for frequency
and direction or quadrature format.
The position is latched on the
rising edge of Z when the direction
is forward and on the falling
edge when the direction is reversed.
Termination resistors can be selected
by a parameter and do not have
series capacitors. Input filters
and over voltage protection are
fitted to all three inputs. The
inputs comply EIA485. |

| User Outputs
|
| |
| The F and D outputs,
enable the user to monitor the
Frequency and Direction of the
encoder/Drive signals. The F and
D outputs are derived from either
the main encoder inputs or the
encoder inputs to this module.
The resolution can be reduced
by any power of 2 and the format
of the output can be either frequency
and direction or quadrature. Delay
encoder (main or 2nd) input to
output 1μs. |
|
| |
| User input/output |
|
|
| The signal
can be programmed as a freeze
input or a Z output by setting
the appropriate parameter.
If the Z output is chosen
the output is a buffered
version of the Z input of
the main encoder. If used
as a freeze input when a
positive transition is detected,
the position of both the
main encoder and the 2nd
encoder inputs are stored.
There may be a small delay
in latching the position
but both will be latched
together. Output and Input
modes comply with EIA485.
Termination resistors are
parameter selectable and
do not have series capacitors.
