Figure 5.1: Assembly of parts
We recommend a minimum distance between the TMCM-013 and motor of 5mm. The module can be
directly attached to the motor backbell with an electrical insulation spacer. Appropriate cooling might
be necessary if the motor itself gets very hot.
5.2 Motor
Do not connect or disconnect the motor while power on. Damage to the module
may occur.
5.2.1 Motor Choice
Care has to be taken concerning the selection of motor and supply voltage. In the different chopper
modes different criteria apply. Modes 0 and 1 are quite insensitive to the motor choice, while Mode 2
is very sensitive, because it uses a different motor current regulation scheme. This chapter gives
some mathematical information on the motor choice, but you can skip it if you want to experiment with
a given motor. Normally, best results will be achieved when operating the given motor in a range of 50
to 100% of nominal motor current (see motor data sheet). Mode 2 and mode 1 are mainly intended for
slow, smooth and very exact movements, due to the high microstepping resolution. For dynamic
operation choose mode 0.
