Change In Feedback Resolution With Change Of Maximum Speed; Simulated-Encoder Outputs (Terminals 40, 41, 43, 44) - Control Techniques UD53 User Manual

5.3 Change in feedback resolution
with change of maximum speed
The resolver feedback signals are sampled by the UD53 at a resolution that
depends on the maximum speed of the Drive. (This is determined by the
value of 1.06 Maximum speed, and when 1.08 Negative minimum speed select
is set at 1, it can also be determined by 1.07 Maximum reverse speed.)

Maximum speed [1.06]
3001 ~ 12000
Note that the simulated-encoder outputs are affected by the value of 1.06
(and/or 1.07). See Simulated-encoder outputs.
5.4 Simulated-encoder outputs
(terminals 40, 41, 43, 44)
The simulated-encoder outputs can be connected to external equipment for
monitoring the output of either a resolver connected to the UD53 or the
main encoder (Encoder 1) that is connected to the 15-way D-type on the
Drive. By default, the resolver is used as the source. To select Encoder 1,
set parameter 16.06 Simulated encoder output select at 1.
Quadrature AB, or frequency and direction
By default, the simulated-encoder outputs are phase-quadrature A and B
signals. For frequency (F) and direction (D) signals, set parameter 16.08
Simulated-encoder F/D output enable at 1.
