TU834 module ABB
Technical data of product parameters
The SERVOSTAR provides a motor position output to you in the form of quadrature encoder
signals eliminating the need for an additional position feedback device. The outputs are
differential line drivers. There is an associated DC common output (C4: pin 3) which can connect
to your port to keep common mode noise and voltage spikes minimized for device protection.
Because there are normally differences of potential between your controller and the drive,
connection is recommended (if ground loops occur, disconnect and retest).
The source of the Encoder Equivalent Output (EEO) signals depends on the type of motor
feedback TU834Startup Danaher Motion Kollmorgen Speciality Electronics

The output signal is developed through the R/D hardware circuitry for minimal phase lag and has
a maximum frequency determined by the motor speed and R/D limits. It provides a configurable
TU834 resolution of up to 16384 lines (65536 quad counts) per revolution of the motor
shaft. The placement of the index pulse TU834 can be varied on resolver systems within
360 electrical degrees of the feedback signal. For single-speed resolvers, this means you can vary
the position of this signal over one mechanical revolution. For multi-speed resolvers, the
mechanical position variation is determined by the pole-pair count of the resolver (e.g. threespeed resolver gives mechanical variation of the pulse within 1/3 of a revolution)
