interface modules for PTO (Pulse Train Output) TM PTO 4
Uniform display and diagnostics concept:
Module status display for ERROR (red LED) and RUN (green LED)
Channel status display for signal state log. "0" and log. "1" for digital inputs and outputs
Display for monitoring the 24 V DC supply voltage (green LED)
Interfaces for each axis (configurable):
2 digital outputs for speed as frequency and direction
1 digital output for "Enable Drive"
1 digital input for "Drive Ready"
1 digital input for a reference point switch
Depending on the signal interface, one more digital input for using with the Measuring Input technology object
Signal interface for speed and direction:
24 V asymmetrical
RS422, 5 V symmetrical
TTL 5 V asymmetrical
Signal types; data for speed and direction can be transmitted in various ways. There are 3 different signal types to choose from:
Pulse and direction
Pulses for forward movement and pulses for backwards movement
2 phase-shifted signals, as used by many incremental position encoders. One complete period can be selected as 1 increment or one period can represent 4 increments.
Supported functions, controlled by the higher-level axis:
Reference point approach
Measuring input
Control of the drive state via "Enable Drive" and "Drive Ready"
Error handling
The TM PTO4 is compatible with the technology objects of the S7-1500 and S7-1500T
Positioning axis
Speed-controlled axis
Synchronous axis
SIMATIC S7-1200 positioning axis (FW V4.0 or higher)
