microcontroller..
UART: support 10 commonly used baud rate, compatible with both 3.3V and 5V systems.
1.9 Control mode
Open-loop speed control mode: this mode applies to the open-loop motor control mode (without
encoder), the motor speed is based on the control variable.
Closed-loop speed control mode: this mode applies to the closed-loop motor control (with encoder).
You could set the encoder parameter (via the UART interface) to achieve closed-loop speed control.
1.10 Protection function
In UART mode, the fault information can be gotten via the "GER" instruction, please refer to the
drive I
nstruction set
. In PPM and Analog mode, the error can be checked through the combination
of Set, Analog, PPM, UART led, as shown in the following table (Note: any kind of failure occurs,
the motor will stop working, enter fault mode, in which case, the user will not be able to control the
motor. In UART mode, the fault information could be cleared via the "CER” instruction to return to
normal mode. In PPM and Analog mode, only it could eliminate the fault information by resetting
the drive.):

Reverse power protection, when power is reversal connected, power supply reverse polarity indicator
light up (Reverse), indicating fault.
You can set the threshold of the under-voltage and overvoltage protection. If the input voltage
exceeds the set range, the fault led (Error) will be on, and the drive will go into fault mode.
You can set the maximum allowable continuous current protection. Actual when the current is higher
than the maximum allowable continuous current, and less than the maximum allowable peak current,
it could continue to be 2s, if time exceeds 2s, the fault led (Error) will be on, the drive will go into
fault mode.
You can set the maximum allowable peak current protection. Actual when current is higher than the
maximum allowable peak current, it could continue to be 400ms, if the time exceeds 400ms, the fault
led (Error) is on, the drive goes into fault mode.
You can set the maximum allowable temperature protection. When the internal temperature is higher
