The TIP102 family are 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 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 optocoupler. 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 quadruple analysis of the encoder two phase signals.

Calibration of the position feedback to an absolute reference point is done by a 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.
