Main features of the UD52

Note
The UD52 can be used only with Drives equipped with
version 3 (or later) software. (Parameter 0.50 indicates
the software version.)
Applications The UD52
installation in a Unidrive. The UD52 operates with encoders having 256,
512, 1024, 2048 or 4096 lines per revolution, and has a maximum operating
frequency of 102.4kHz (3000
The UD52 can be used in a Drive operating in either the Closed-loop Vector
or Closed-loop Servo mode in order to obtain speed feedback and very
high resolution shaft position. The UD52 is fully compatible with the
following Stegmann
SCS60, SCM60, SCS70, SCM70
These encoders are compatible with the two-wire serial communications
port in the UD52.
The UD52 can determine the absolute position within a revolution of a
Absolute-
position single-turn encoder, or in many revolutions of a multi-turn encoder. Unlike
information the case for a standard encoder, which must be rotated past its marker
pulse in order to obtain absolute-position information, absolute-position
information from a (suitable)
powered-up.
Speed and position information is displayed in parameters which can be
read on the Drive display and/or via serial communications.
When a UD52 is fitted in the Drive, the Drive automatically uses the
Selection of
encoder encoder as speed and position feedback for the motor. Alternatively, a
function standard quadrature encoder can be used for speed and position feedback,
and the
SIN
Simulated The UD52 has simulated encoder outputs which normally use the
encoder encoder as the source, but can be reconfigured to use the main encoder
outputs (Encoder 1) connected to the 15-way D-type on the Drive as the source.
These outputs produce quadrature A/B signals corresponding to the line
counts from the source encoder. Also, these outputs can be configured for
frequency and direction (F/D) signals.
The UD52 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 pluggable 16-way
screw-terminal block on the UD52.
