6.3 Step/Direction
Each positive edge of a square wave signal corresponds to a step movement. The acceleration and velocity is varied with the
applied signal frequency. The amount of counted positive edges determines the goal position.
NOTE
Step/Direction mode is momentarily available for Stepper Motors only.
Example
With a Step Mode of 1/1, a Step Angle of 1.8° and a frequency of 200 Hz, the motor executes one revolution per second, i.e. 60
revolutions per minute.
To control the motor in the "Step/Direction" mode, proceed as follows:
1.
Set the values for “Max. Velocity”, “Jog Velocity” on the “Axis” page under “Movement limits” to 100.000 and “Max.
Acceleration” to 1.000.000
2.
Set the DI 7 “Enable” signal (external signal or switch on the "Inputs/Outputs" page)
3.
Set the movement direction by setting DI 2 "
Direction”
4.
Apply the square wave signal frequency at DI 1

The movement can be stopped by ceasing the
signal frequency at DI 1 “Clock or revoking DI 7 “Enable“.
If a rotation direction change is to be executed, DI 2
“Direction” must be changed after the last negative edge of the “Clock”
signal. The
“Direction” signal must be set at least 10 µs after the last negative edge and at least 10 µs before the first positive
edge of the
“Clock” signal and must be applied continuously. To ensure that all impulses are counted, it is required to change
the
“Direction” signal only when the level of the “Clock” signal is 0.
