than 40
℃
and less than the limit temperature, the drive automatically open the radiator until the
temperature dropped below 35
℃
. When the internal temperature exceeds the limit temperature, fault
led (Error) will be on, and the drive will go into fault mode.
In PPM and UART mode, you could set it to be the discontinuous mode via the “SSM” instruction. If
there is no valid control signal input in the limit time, the fault led (Error) will be on, and the drive
will go into fault mode.
The driver can run in unidirectional control mode or bidirectional control mode. In the unidirectional
control mode, you could start zero detection via “SSD” command. When the driver restarts, if the
initialize speed signal is not zero, the drive will be stop unless the control signal drops to zero. This
is zero detection protection.

2 Practice guide
So far, maybe you still don't know what to do with this drive, maybe you feel a bit complicated. But
it is just “maybe”, then I will introduce this simple dual brush DC motor drive. At the beginning of
this section, first, I will show you a brief description of several associated control parameters.
Direction Mode:
This parameter is only valid in Analog mode and PPM mode. It decides its running mode:
unidirectional control mode or bidirectional control mode.
Zero Detection:
This parameter is only valid in Analog mode, PPM mode and unidirectional control mode. It decides
whether it need to start the detection of the zero start. (It will detect whether there is a speed signal
before running. If there is a signal, it won’t start until the signal drop to zero.)
Signal Control Mode:
This parameter is only valid in PPM mode and UART, cooperated with “intermittent mode time
limit” parameter, and decided whether stopping motor during operation, when it loses control signal.
In addition, there are some brief introductions about factory default values of drive :
