TIP102 Motion Controller using Incremental Encoder

Application Information

The TIP102 family consists of IndustryPack® compatible

modules with complete one or two axes high precision

motion control interfaces, using incremental encoder with

RS422 or TTL signal level for position feedback. The

transition module TIP102-TM-xx is required for the signal

conditioning and optional galvanically isolation of the

various input and output signals.

The position feedback is provided by an incremental

encoder interface and a 24 bit up/down counter. The level

of the encoder signals can be TTL or RS422. Optionally,

the encoder signals can be isolated on the transition

module by high speed optocouplers. The encoder signals

pass a digital filter for noise suppression before they are

fed into the counter and the reference logic. The counter is

programmable for single, double and quadruples analysis

of the two encoder phase signals.

Calibration of the position feedback to an absolute

reference point is done by programmable reference logic.

Several modes of operation and hardware configurations

for the reference switch and the encoder zero pulse are

selectable.

During

normal

operation

the

automatic

recalibration of the measurement system is practicable

with the “Auto-Reference” mode, whenever the system

passes the reference location.

Two isolated 24V DC digital inputs have limit switch

functionality. Each of these inputs drives a floating

optocoupler output as hardware feedback. These outputs

can be used to disable the power on the motor power

amplifier,

dependent

on

the

actual

direction.

One

additional isolated 24V digital input is for free use by the

software, for example as emergency stop input. A floating

optical output can be controlled by software, for example

as enable signal for the motor power amplifier.

A 16 bit digital to analog converter (DAC) produces a

+/-10V controller output signal which can be used as

speed or torque source for the power amplifier of the

motor drive system. A galvanically isolation of this signal

with the help of an isolation amplifier will be supplied as a

transition module option.

A 12 bit analog to digital converter (ADC) with a

configurable input voltage range is also available.

For First-Time-Buyers the Engineering Documentation

TIP102-ED

is

recommended.

The

Engineering

Documentation includes TIP102-DOC, schematics and

data sheets of TIP102 and TIP102-TM.

Driver support (TIP102-SW-xx) is available for different

operating systems.
