7.4 Step control
The application enables simple internal control of step/dir pins. It allows a test of basic driving
capabilities of the PoStep60 driver.
Figure 11: Step control controls
1. Speed slider – use this slider to set step speed. Please note the maximum value is limited by
“Max speed” value.
2. Max speed dial – set maximum step speed to limit the step speed value set by “Speed” value.
3. Stop – stops internal step/dir generator and switch the pins control to external controller.
4. Auto update – if checked, any change in step speed value is sent to driver immediately.
5. Manual speed set – send new step speed value to driver if “Auto update” is disabled.
6. Auto stop – when checked step speed resets to zero when slider is released.
7.5 Auto control
7.5.1 Position control mode
Simple position control algorithm is implemented in the driver. The driver moves to required position
using standard “Trapezoidal motion profile” where acceleration, deceleration, and maximal speed is
defining the profile. Required position can be set using input box or slider. End switches (NC or NO;
please note – end switch reacts only on change of end switch state.) and position limits can be used
to define/limit a range of movement. The provided position control allows a test of basic driving
capabilities of the PoStep60 driver and is not intended to replace external controller.
NOTE!
If driver is used in combination with external controller or BOB please make sure to
stop the application step/dir control by pressing button “Stop”. This way external
controller takes over control of the step/dir pins again.
