DRST（
The DRST terminal does not need to be connected when a stepper motor is used.
When the servo driver counter reset input is +5V interface, refer to the connection
example below.
If the current-limiting resistor of the driver is less than 150Ω, provide an external resistor
to ensure 150Ω or more.
