TIP111 Motion Controller using absolute Encoder (SSI)

Application Information

The TIP111 family are IndustryPack

® compatible modules

for motion control applications using absolute encoder with

a serial interface (SSI) as position feedback.

There are two versions available: The TIP111-1x is the

implementation of a one axis controller and the TIP111-2x

offers a two axes controller on a single size IP. The

transition module TIP111-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 absolute encoder

with

a

synchronous

serial

interface

(SSI)

and

a

corresponding 32 bit shift register at the IP. 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 optocoupler. The TIP111 can handle data

stream which are encoded in Binary or in Gray Code.

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.

Two

additional isolated 24V digital inputs are 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

TIP111-ED

is

recommended.

The

Engineering

Documentation includes TIP111-DOC, schematics and

data sheets of TIP111 and TIP111-TM.

Software support (TIP111-SW-xx) is available for different

operating systems.
