OMC/TMC Programmable Stepper Motor Controller OMC/TMC Stepper Motor Controllers Various Operation Modes 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 voltage. 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. The connection of external power stages allows to connect larger stepper motors e. g. 17 APEAK at 140 V motor voltage. 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. 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. Stand-alone mode for single devices The controller is able to execute program sequences without connection to PC. OMC offers 16 inputs, which are electrically isolated from the controller board, and 8 overload protected outputs. TMC has 32 inputs and 16 outputs. Stand-alone multi-axis mode Up to 30 axes can be simltaneously operated by PC: RS 422/RS 485-4-wire bus mode. 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. 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).

Operating Modes / Controller Board / Power Stages / Stepper Motor Controller Board OMC Single Axis Controller / Stand-Alone Mode OMC/TMC are controlled by an ‘intelligent’ motion controller. This compact ‘all-rounder’ executes sequence programs, scans inputs, sets outputs and evaluates limit switch signals. Step resolution from 1/1 to 1/20 steps and linear or s-shaped positioning ramps are also set by the controller board. Example: PC online operation / Programming with MiniLog-Comm The 24 VDC supply voltage for the controller board supplies simultaneously the limit switches. TMC Dual Axes...

SFI / AD Converter/ Ethernet Adaptor / Operator Panel / Dimensions Step failure indication for stepper motors with encoder. Emergency stop in case of exceeding a given deviation between set and real position. For encoders with 2 or 3 cannels Power supply: +5 VDC / max. 150 mA per encoder is provided by the controller. Option AD Converter 14-bit-AD-converter board for connecting e. g. a joystick Input resistance: > 8 kOhm Max. current: 20 mA Resolution: 14 bit, digital value between 0 and 16384 incl. prefix Conversion time: 6 m sec OMC: 4 inputs TMC: 2x4 inputs DIN Rail Mounting Clip...

Communication Software / Desktop / Accessories / Ordering Code MiniLog-Comm® Software Example: MiniLog-Comm® Desktop MiniLog-Comm, a Windows® PC software for configurating and programming, is included by delivery of the OMC/TMC controller. MiniLog-Comm can set up parameters and execute program routines without PC connection. Optionally, instructions can be handled by individual software. Readable ASCII string instructions and functions can be edited with LabView, Hyper Terminal or C language. So it is possible to transmit parameters to each OMC/TMC during initialising or changing a module...
