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 an one axis controller and the TIP111-2x offers a two axes controller on an 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.
