MODULE FOR STEPPER MOTORS MODULE TMCM-1043 STEP/DIR DRIVER BOARD Cost-effective 1-axis Step/Dir stepper motor driver board for 2-phase bipolar stepper motors D ESCRIPTION Th e TMC M -1043 is a simple and compact 1-axis driver bo ard. It allows motor control via step and direction signals and can be directly controlled via a PLC or by an external Step/Dir controller board. Handling is quite easy and no further configuration is required. Nominal supply voltages are 12V DC and 24V DC. The drive capability is fixed at 1.1A RMS. The module provides a very high microstep resolution and TRINMICs spreadCy cle chopp er for sm ooth m otor mov e m ent. The TMCM-1043 is equipped with an error output and an additional output. The board fits directly on the back of a NEMA17 stepper motor. Using the TMCM-1043 USB serial programmer kit, the MAIN CHARACTERISTICS TMCM-1043 can be configured for up to 1.4A RMS 2-phase stepper motor driver board current resp. 2A peak. Further, standby current can be used. Step/Dir Interface On-board Processor for initialization and diagnostic Fixed Drive Capability 1.1A RMS (1.6A peak current) or Program.

One kit includes a power supply unit, the programmer, cables, and three TMCM-1043 modules. Caution! Add external power supply capacitors! ! It is recommended to connect an electrolytic capacitor of significant size to the power supply lines next to the TMCM-1043. Rule of thumb for size of electrolytic capacitor: Do not connect or disconnect motor during operation! ! Motor cable and motor inductivity might lead to voltage spikes when the motor is disconnected / connected while energized. These voltage spikes might exceed voltage limits of the driver MOSFETs and might permanently damage them. Therefore, always disconnect power supply before connecting / disconnecting the motor. ! Keep the power supply voltage below the upper limit of 28V! Otherwise the driver electronics will seriously be damaged! Especially, when the selected operating voltage is near the upper limit a regulated power supply is highly recommended. ! There is no reverse polarity protection! The module will short any reversed supply voltage due to internal diodes of the driver transistors. Disclaimer TRINAMIC Motion Control GmbH & Co.
