6.3.2 Step
Description: The Step signal adjusts the velocity and acceleration of the motor. The velocity is
depending on the frequency, the acceleration on the change of it. One step impulse represents one
microstep.
Calculation of rotations per second (refer to 6.2.1.11):
Frequency: The maximum Step input frequency is 350 kHz, aligned to the Direction signal. The
minimum logic ”0” time is 0.7 µs and the minimum logic “1” time is 2.0 µs.
Maximum frequency at a duty cycle of 1 (“0” time is 2.0 µs and “1” time is 2.0 µs) is 250 kHz.
Function Table:
6.4 Reset to factory default
If the module seems to function weird this could usually is caused by unintended settings. In this case
a reset to factory default might be useful. To do this switch off the module and short-circuit pin 1 and
pin 3 of the free contacts for a 6-pin connector on the backside of the module. See Figure 6.4. Turn on
the module and switch it off again to remove the short-circuit. All settings are now at factory default.
