5.5 Motor Current setting
The motor current can be set in a range of 0 to 255, using the TMCL software. 255 corresponds to the
module’s maximum I
5.6 Step / Direction Interface
5.6.1 Direction Input
The direction signal changes the motors rotation from clockwise (CW) to counterclockwise (CCW) and
vice versa. A change in the direction signal has to be aligned to the step pulse in order to specify the
direction of each step (please refer to setup -/ hold times).
5.6.2 Step Input
The step signal directly influences the velocity and acceleration of the motor. The velocity depends on
the frequency, the acceleration on the frequency’s change per time.
Frequency: The maximum step input frequency is 350 kHz. The minimum logic ”0” time is 0.7 µs and
the minimum logic “1” time is 2.0 µs.
