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
The TMCM-1043 is a simple and compact 1-axis driver
board. 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
spreadCycle chopper for smooth motor movement. 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
TMCM-1043 can be configured for up to 1.4A RMS
current resp. 2A peak. Further, standby current can be
used.

Note: TRINAMIC offers the TMCM-1043 USB serial programmer kit which can be used to configure the TMCM-1043 for
up to 1.4A RMS. 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.
