1 Features
The TMCM-1241 is a single axis motor controller/driver board for 2-phase bipolar stepper motors with
up-to 3A RMS (4.3A peak) motor coil current. It supports linear ramps and unique sixPoint™ramps. It
offers on-board sensOstep encoder and in addition, support for connection of external (incremental A/B)
encoder. For driver-only applications, the TMCM-1241 offers optically isolated Step/Direction inputs. When
using the on-board motion controller the optically isolated inputs are used for connection of end-switches.
The standard version of the TMCM-1241 offers one analog input (0..10V range), two digital inputs and
one open-drain output (100mA load max.) For communication in addition to USB (Micro-USB connector),
RS485 and CAN serial interfaces are available. USB is intended mainly for rmware updates and param-
eter settings - supporting USB-powered operation (just the digital part) for easy data tranfer between
PC and TMCM-1241 module. With CANopen rmware CANopen protocol is supported via the CAN interface.
Motion Controller
• Motion pro le calculation in real-time
• On the y alteration of motor parameters (e.g. position, velocity, acceleration)
• Linear and unique sixPoint™ramp in hardware
• Encoder interface and Reference / Stop switch inputs
Driver
• Motor current: up to 3A RMS / 4.3A peak (programmable in software)
• Supply voltage: +24V DC (+10. . . +30V DC)
• 256 microsteps per fullstep
• spreadCycle™highly dynamic current control chopper
• stealthChop™for quiet operation and smooth motion
• programmable Step/Dir interface for driver-only applications with microstep interpolation
Encoder
• integrated sensOstep absolut position magnetic encoder (resolution: 1024 increments per rotation)
for step-loss detection under all operating conditions and positioning supervision (accuracy: +/- 5
encoder steps)
• support for external A/B incremental encoder in addition / as an alternative for the integrated
encoder
• programmable encoder scaling and support for motor stop on encoder deviation
Interfaces
• RS485 interface (up-to 1Mbit/s)
• CAN interface (up-to 1Mbit/s)
• USB 2.0 full speed (12Mbit/s) device interface (micro-USB connector)
• Step/Dir input (optically isolated)
• Left and Right STOP switch inputs (optically isolated, shared with Step/Dir inputs)
• 2 general purpose digital inputs

2 Order Codes
The standard version of the TMCM-1241 is pre-programmed with either TRINAMIC TMCL™ rmware or
CANopen rmware.
On request a version with 3 analog inputs (0..10V) is available instead of one analog and two digital
inputs on the I/O connector of the TMCM-1241. As this is an assembly version with different components
concerning these inputs, only all mechanical data and all other electrical data are the same.
