(2) See bit 7 of Drive_Working_Settings.
(3) See Drive_Inputs_Setting and Direct_Command_CMD objects and Movements with Trigger.
(4) See Drive_Inputs_Setting and Direct_Command_CMD objects.
(5) Enabling the Start/Stop Trigger function (from Direct_Command_CMD objects) on the selected input sets a digital filter that limits the maximum input frequency to 5 Khz. Make sure to use a different input for counter functionality. Once the digital filter is set, it will remain set until system switch off.
Examples:
Reading the position of an incremental encoder:
-
Connect the two encoder phases to digital inputs B0_IN2 and B0_IN3.
-
The Encoder_Actual_Value[01] object, returns the position of the encoder connected to digital inputs B0_IN2 and B0_IN3 while the Encoder_Frequency[0÷1] object returns the encoder pulses frequency.
Reading the pulses from an external clock & direction source
-
Connect the clock source to digital input B0_IN3.
-
The Encoder_Actual_Value[01] object, returns the pulses number generated by external clock source while theEncoder_Frequency[0÷1] object returns the pulses frequency.
-
Connect the clock source to digital input B0_IN3, and the direction signal to B0_IN2.
-
The Encoder_Actual_Value[01] object returns the pulses number generated by external clock source (positive or negative depending on the direction signal) while theEncoder_Frequency[0÷1] object returns the pulses frequency.
