Instruction：
 Height-adjusting device wiring with corner low-speed
When the height-adjusting device takes corner low-speed input control signal, the
system's "corner low speed" output signal is used to control the height-adjusting device's
corner low-speed input. The system takes an open-collector transistor output, with the
default active low signal. Reference section 8.7.3, set the output port type of close THC
(corner signal) “●”. CNC system needs to output low electrical lever signal with this
