8 Differences between Hardware rev.

1.1 and 2.0

There are two versions of the TMCM-310: hardware rev 1.1 and hardware rev. 2.0. Both of these
versions of the TMCM-310 are compatible with each other, but there are some slight differences.
These differences are listed here:

•

Power supply: rev. 1.1 is equipped with a bridge rectifier, and thus the polarity of the supply

voltage does not matter and can even be alternating current. But as this caused problems
when connecting external SPI devices (grounding problems), the recfier has been eliminated
on hardware revision 2.0. The rev. 2.0 module is equipped with a diode that protects the
module against wrong polarity (the suplly voltage will be shorted if the polarity is wrong!).

•

Alarm input: rev 1.1 is equipped with a jumper that controls the shutdown functions of the

motor drivers. On rev. 2.0 this jumper has been eliminated. Instead, an alarm input has been
introduced on the additional I/O connector. This leads to more flexibility, as the functionality of
this input can be configured by TMCL. It also makes the external I/O connector fully
compatible with the one on the TMCM-610 and TMCM-612.

•

Connecting external SPI devices: This has been simplified on hardware rev.2.0 of the TMCM-

310 module. Please see chapter 4.5.3 for more information about this.

•

SPI jumpers: As these jumpers were hardly needed they have been eliminated on hardware

rev. 2.0 and replaced by cuttable PCB wires and soldering pads.

•

Voltage regulator: The voltage regulator of the module has been improved for better EMC

behaviour.
