Phytron: Stand-Alone Controls (OMC/TMC Series)

Compact Stand-alone Controls for 1 or 2 axes and Multi-Axis Systems up to 30 Axes.

The intelligent motion controllers OMC and TMC are small, simple and compact stepper motor control units for 2-phase stepper motors up to 9 Apeak phase currents with 70 V motor PEAK voltage. The connection of external power stages allows to connect larger stepper motors e. g. 17 Apeak at 140 V motor voltage. The controllers are applicable for more complex processes and motion sequences because of the circular interpolation and changes of frequency and target position during the run.

OMC offers 16 inputs, which are electrically isolated from the controller board, and 8 overload protected outputs. TMC has 32 inputs and 16 outputs. Two signal inputs are available for each axis to connect the limit switches. The controllers can be supplied from 24 up to 70 VDC or 17 up to 50 VAC . OMC and TMC are designed for DIN rail or OMC/TMC are programmed in the well-tried MiniLog format. The user-friendly MiniLog-Comm® , Windows® PC software for configuration and programming, is included in delivery.

A Remote/Local switch makes it possible to start and execute the saved program routines without connection to the superior control. Each OMC or TMC control unit can be used in single or multi-axis mode.

Stand-alone mode for single devices.

The controller is able to execute program sequences without connection to PC.

Stand-alone multi-axis mode.

Up to 30 axes can be simultaneously operated by PC: RS 422/RS 485-4-wire bus mode.

Master-slave mode.

The connector with the address ‘0’ is defined as master. The instructions are sent from the PC to the master and from the master to the slave controllers (up to 8 axes).
