1. Enable DC motor control – enables and disables DC motor control.
2. Channel A – Slider and input box for PWM value for DC motor connected to output terminals A
3. Channel B – Slider and input box for PWM value for DC motor connected to output terminals B
4. Set PWMs – send new values to driver manually
5. Frequency dial – set PWM frequency (period)
6. Frequency input box – set PWM frequency (period)
7. Auto update – send new values to driver automatically if checked
8. Stop – sets PWMs to zero and put open collector inputs to high state enabling external PWM
controller PWM control
7.7 Log charts
PoStep60 application enables simple log of major driver parameter through time. By the chart the
driver temperature can be monitored for possible overheating. This way driver setting can be
adjusted or heat dissipation elements checked for its performance.

1. Clear log data – Clears log charts data.
NOTE!
Enabling or disabling DC motor control puts driver into stand-by to prevent sudden
movement of motor or accidental overheating of stepped motor winding.
NOTE!
If driver is used in combination with external controller or BOB please make sure to
zero PWM values by pressing button “Stop”. This way external controller takes over
control of the PWM inputs again.
