TM PTO 4 Interface Module for PTO (Pulse train Output)

With this module it is possible to control stepper motor drives or servo drives with PTI interface. Supported are 24V asymmetrical, RS422 symmetrical and 5V asymmetrical as signal interface. It is particularly suitable for control with an axis technology object of the SIMATIC S7-1500.
The module offers 4 identical channels with the following characteristics:
PTO interface for output of position and velocity information on various interfaces

  • 24 V asymmetrical up to 200 kHz

  • RS422 symmetrical (5V differential signal) up to 1 MHz

  • TTL (5 V) asymmetrical up to 200 kHz

The signal type can be selected between:

  • Pulse/direction: The pulse signal determines the speed and driving distance, the direction signal determines the direction.

  • Count forward / count backward: one signal outputs the pulses in forward direction; the other signal outputs the pulses in reverse direction.

  • Incremental encoder A/B phase-shifted: 2 tracks are output whose signals are phase-shifted by 90°. The direction, the distance and the velocity can be determined by the signal sequence. It can be selected whether a full period stands for 1 increment or whether all 4 flank changes are to be counted.

The output pulses are counted internally and reported to the CPU as the current actual position.

Depending on the configuration, additional functions are available for controlling an axis:

  • Digital output for issuing the enable signal for starting the drive

  • Digital input as input for reading in the “drive ready” message of the connected drive

  • Digital input as reference point switch for synchronizing the axis with the mechanics

  • Digital input as measuring probe input for flying measuring tasks during movement with the technology object measuring probe

The module is particularly suitable for connection to a technology object in the SIMATIC S7-1500 and S7-1200. This provides a consistent solution for PTO functionality in the compact CPUs of the S7-1500 and S7-1200.
The following technology objects are supported:

  • Synchronous axis

  • Positioning axis

  • Speed axis

  • Measuring probe
