PUL、DIR(IN1, IN2) Port:
When working in external pulse command mode by default, R86Mini can receive two pulse command signals: PUL + DIR and CW + CCW.
The command form of the external pulse is set by the debugging software.
ENA (IN3) port:
The default ENA port is the drive offline (enable) function:
When the internal optocoupler is off, the driver outputs current to the motor;
When the internal photocoupler is turned on, the driver will cut off the current of each phase of the motor to make the motor in a free state. At this time, the step pulse is not responded.
When the motor is in an error state, the automatic disconnection is enabled.
The level logic of the enable signal can be set to the opposite.
At the same time, this port can be reused as other functions like IN1 and IN2.
ALM (OUT1) port:
The driver contains an optically isolated output port ALM. By default, the ALM port is an alarm output. When the driver is in an error state and normal working state, ALM outputs different optocoupler levels.
At the same time, it can also be reused as other functions.
The USB is a micro usb connector, you need to install a USB driver
Missing phase alarm
The driver has a motor phase loss alarm function, which can detect the phase loss state that occurs when the motor is stationary and in motion. During the operation of the stepper motor, due to mechanical reasons, the winding wire of the motor may be loosened or disconnected. At this time, the driver will output an alarm signal to prevent the device from making erroneous actions.
Since this function depends on the current detection of the motor winding, when the motor current is too small (less than 300mA), this function has false alarms. At this time, the user can turn off this function. In the parameter management and setting interface of the debugging software, Set parameter 188: Phase loss detection enabled, set to 0.
Internal motion control function
When working in the internal pulse command mode, the PUL and DIR ports are used as IO input signals. The function of IO needs to be set by the debugging software RStepper Configurator. As shown below:
