module for stepper motors module trinamic motion control gmbh & co. kg hamburg, germany tmcm - 1043 step/dir driver board 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. h andling is quite easy and no further configuration is r equired. 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. t he tmcm - 1043 is equipped with an error outp ut 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. m ain c haracteristics 2 - phase stepper motor driver board step/dir interface on - board processor for initialization and diagnostic fixed drive capability 1. 1 a rms ( 1.6 a peak current) or program. drive capability up to 1.4a rms (2a peak) voltage range 12 24v dc nominal (9 28v max.) microstep resolution 16 microsteps per full step input step multiplier 256 microsteps per full step output with *16 step multiplier error output overtemperature spreadcycle? high - precision chopper compact size 37 x 37 x 8.2mm 3 temperature range - 30 5 0?c mounting 4 holes for m3 screws for nema 17 motors i nterface and p ower c onnector pin label description 1 gnd system and module ground 2 +24v power supply +24v dc nominal 3 out_2 output 2 4 out_1 e rror output (overtemperature) 5 com supply for optocoupler inputs 6 enable enable signal input 7 dir direction signal 8 step step signal input m otor c onnector pin label description 1 a1 motor coil a 2 a2 motor coil a 3 a3 motor coil b 4 a4 motor coil b o rder c ode tmcm - 1043 s/d stepper driver board c ost - effective 1 - axis step/dir stepper motor driver board for 2 - phase bipolar stepper motors 9 2 8 v d c c m o s f e t d r i v e r s t a g e t m c m - 1 0 4 3 i n i t i a l i z a t i o n d i a g n o s t i c p o w e r d r i v e r s t e p / d i r o u t 1 = e r r o r o u t 2 s p i m o t o r t m c 2 6 6 0 3 4 4 x m 3 3 7 3 4 3 7 3 3 1 1 x 2 x 1 m o t o r i n t e r f a c e / p o w e r 4 3 2 1 8 7 6 5 1 2 3 4 m o t o r c o n n e c t o r i n t e r f a c e a n d p o w e r c o n n e c t o r s t e p / d i r o u t 1 / 2 p o w e r g n d a 1 a 2 b 1 b 2 p l u g t y p e : j s t b 4 b - p h - s m 4 - t b m a t i n g p l u g : j s t p h r - 4 p l u g t y p e : j s t b 8 b - p h - s m 4 - t b m a t i n g p l u g : j s t p h r - 8
tmc m - 1043 v1.3 manual (rev. 1.0 1 / 2013 - nov - 30 ) www.trinamic.com examples: step/dir circuit s note: trinamic offers t he 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 sup ply 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 recommend ed. 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. kg does not authorize or warrant any of its products for use in life support systems, without the specific written consent of trinamic motion control gmbh & co. kg. life support systems are equipment intended to support or sustain life, and whose failure to perform, when properly used in accordance with instructions provided, can be reasonably expected to result in personal injury or death. information given in this data sheet is believed to be accurate and reliable. however no responsibility is assumed for the consequences of its use nor for any infringement of patents or other rights of third parties which may result from its use. specifications are subject to change without notice. all trademarks used are property of their respective owners. revision history version date autho r sd C sonja dwersteg description 1.00 2013 - dec - 03 sd initial version 1.01 2014 - mar - 24 sd current range programmable with tmcm - 1043 usb serial programmer. 8 m a 8 m a 8 m a + 3 . 3 v + 2 4 v t m c 2 6 6 0 t m c m - 1 0 4 3 g n d d i r g n d s t e p g n d e n a b l e g n d 8 m a 8 m a 8 m a + 3 . 3 v + 5 v t m c 2 6 6 0 t m c m - 1 0 4 3 g n d 7 4 h c t 0 8 7 4 h c t 0 8 7 4 h c t 0 8 e x a m p l e 1 : c o m = + 2 4 v e x a m p l e 1 : c o m = + 5 v !
