Main features of the UD53

The UD53 Resolver small option module is an interface module for
Applications
installation in a Unidrive. The UD53 operates with resolvers having the
following specifications:
Input impedance: >85Ω at 6kHz
Turns ratio (primary:secondary): 3:1 or 2:1
Excitation voltage: 6V
The Drive must be operating in the Closed-loop Vector or Closed-loop
Servo mode; the resolver connected to the UD53 is used for speed and
position feedback.
Simulated The simulated-encoder outputs produce quadrature AB signals
corresponding to the line counts from the source encoder. Alternatively,
encoder
these outputs can be configured for frequency and direction (F/D) signals.
outputs
In both cases, the outputs retain position infomation when direction is
changed.
By default, the resolver is used as the source for the simulated-encoder
outputs; alternatively, the main encoder (Encoder 1) connected to the
15-way D-type on the Drive can be used as the source.
The number of pulses per revolution can be scaled by factors of 2.
The UD53 must be fitted in the small option module bay of the Unidrive.
Installation
All connections to the Drive are made by a multi-way connector.
Connections from external equipment are made by a plug-in 16-way
screw-terminal block on the UD53.
