Product Features
●New 32-bit DSP technology
●Ultra low vibration noise
●Built-in high segmentation
●Parameter power-on auto-tuning function
●The variable current control greatly reduces the heating of the motor
●The current is automatically halved when driver is still
●Drive 4, 6, 8 leads two-phase stepper motor
●Optical isolation differential signal input or IO control high and low level input
●One driver can drive two motors, with good motor speed synchronization
●The current setting is convenient and can be arbitrarily selected between 2.1-7.2A
●The setting range of speed segment is 40-900RPM
●With over-voltage, under-voltage, over-current and other protection functions

2）Still(Static) current setting
The quiescent current can be set by the SW4 DIP switch, OFF means that the quiescent current is set to half of the dynamic current, and ON means that the quiescent current is the same as the dynamic current. In general use, SW4 should be set to OFF to reduce the heat generation of the motor and driver and improve reliability. After 400ms of the pulse train stops, the current is automatically reduced to about half (60% of the actual value), and the calorific value is theoretically reduced to 30%

Self-Tuning Function
The driver can automatically complete the motor parameter identification and the self-tuning of the internal adjustment parameters within 400ms of power-on; when the motor, power supply voltage and other conditions change, please perform a self-tuning, otherwise, the motor may run abnormally. Note that IO control cannot be input at this time, the direction signal should not be changed, and the enable signal cannot be connected.
Note: This type of driver has the function of automatic tuning of power-on parameters, and can also match parameters for the specified motor.
